## Plastic Pollution Below the Waterline

There is a growing body of evidence that suggests a large percentage of the microfibres in our oceans is the result of washing clothes in automatic machines. Many of those microfibres are from man-made fibres i.e. plastic. It is suggested that up to 30% of the micro plastic pollution in our oceans may come from this source.

One such study detailed in the report “Me, My Clothes and the Ocean” by Ocean Wise and sponsored by the Canadian Government, revealed a surprisingly large variance in the amount of microfibre textiles shed in a single wash; ranging from a loss of 9.6 mg to 1,240 mg, or an estimated 9,777 to 4,315,371 microfibres, per kg of textile washed. Factors include the type of machine, wash cycle, type of fabric, fabric finish and age. Amongst the worst products are fleeces made out of man-made fabrics.

Just think how many kg of clothing a yacht laundry handles on a daily basis!

Various countries are starting to take this plastic pollution seriously. Within our European waters France has already introduced a law (LOI n° 2020-105 du 10 février 2020) that will require manufactures to include microfibre filters in washing machines sold from 2025 and, in the UK, an all-party group of MP’s are trying to introduce similar legislation, and have produced their first report.

### But what has this to do with superyachts?

Unless your yacht has an Advanced Wastewater Treatment System (AWTS) that processes black and grey water, laundry effluent – including the microfibres – is discharged straight into the sea, often at anchor or in port.

Even if an AWTS is installed, the microfibres will end up in the residual sludge that is eventually discharged in compliance with MARPOL at least 12nm offshore. It is not being prevented, just displaced by time and place and still finding its way into our oceans.

So, whilst the industry has been focused on reducing plastic onboard, we may have been ignoring what happens below the waterline. Along with other pathogens, contaminants, and organic matter – see my previous article “What Lies Beneath” grey water is perhaps having a more profound effect on the ocean and marine life than stopping the use of plastic straws or bottled water onboard, especially in the coastal waters where yachts congregate. After all, we play in that water and may also consume seafood that may have been harvested from inshore waters.

Until microfibre filters are installed as standard then the only real solution is to fit external filters to the waste discharge from washing machines.

In a 2020 Bloomberg article, PlanetCare who produce an external washing machine filter, mentioned their filter can fill up in about 20 laundry cycles, after which they are sent back to PlanetCare where the fibres are collected, repurposed and the filters recycled. That would be a day’s use in many superyacht laundries – though they have commercial solutions as well.

Superyachts will require a more practical solution with easy access for cleaning and procedures for storing and disposing of the waste.

With the right filter the superyacht industry has the opportunity to help protect the marine biota and improve sea water quality by removing microfibres before they enter the grey water tank or AWTS and preventing their discharge into the sea.

## Superyacht Crew – OOW Unlimited, An Alternative Worth Considering?

There has been much debate about the quality of education and training for superyacht crew and, of course, the 3000gt limit. On the latter point, not only does this prevent you from working on the largest superyachts, but also restricts career opportunities.

Yes, but the commercial CoC is not practical for yacht crew, it is expensive and time consuming!

As I previously wrote here for those wishing to serve as Master on Yachts >3000gt there is a difference in cost and time due to the breadth and depth of education and training, though when all factors are taken into account and weighed against the benefits, not as much as you might imagine.

Now the option of ‘blended learning’ makes an OOW Unlimited a more attractive, practical and cost effective proposition. In the following piece I take look at this pathway and compare against the traditional Yachting route.

Note: This is based on the UK Maritime and Coastguard Agency (MCA) who developed Yachting training and certification, now MSN 1858, as an equivalent allowed under Article IX of STCW and their requirements for Merchant Navy Deck Officers under MSN 1856.

Education Evolves

The last 18 months has seen an evolution in the way education is delivered; I suspect accelerated by COVD-19. There are now many more education and training establishments that are offering courses online or as ‘blended learning’ where there is a combination of self-study and classroom time; this is also true of maritime education.

One such establishment is Warsash Maritime College who offer OOW Unlimited and Chief Mate/Master Unlimited as ‘blended learning’ following the HNC/HND experienced seafarer route under Merchant Navy Board (MNTB) guidance and MSN 1856.

One of the major benefits of self-study is that you no longer need to spend months at college which, can be expensive due to loss of earnings and expenses – I know what it cost for my Chief Mate/Master Unlimited! You can now study for your CoC whilst still working – Warsash suggest 20 – 24 hours per week.

The Two Main Pathways

The table below summarises the two main pathways – there is also cadetship, but this is not currently widely used in the superyacht industry.

OOW Unlimited via HNC

This includes online studying for a Higher National Certificate (HNC) in Nautical Science that provides the underpinning knowledge for OOW Unlimited. A HNC is a recognised UK academic qualification at level 4 which can then be topped up to level 5 with HND or, even Degree level 6 (BSc). Subjects include:

• Bridge watchkeeping
• Chartwork, Tides, Sailings and Celestial Navigation
• Cargo work
• Meteorology
• Ship Stability
• Ship Construction
• Law and Management

In addition, there are several required courses, some on campus, some online.

• Navigation Equipment Theory and Practice NASET (O)
• HELM (O)
• EDH
• Signals
• Preparation for SQA exams
• Preparation for MCA Signals exam
• Preparation for MCA Oral exam

There are 3 written assessments mid-course, and final SQA exams in Navigation, Stability and Operations.

The total time for the above is around 27 weeks, approx. 20 weeks online and 7 weeks at Southampton Campus and Simulator Centre.

On top of this you would require the STCW short courses, which are the same as for OOW (Y) plus the addition of Advanced Firefighting and Medical First Aid, which make a lot of sense to have anyway.

Some Pros and Cons

Once you add the time and cost for RYA qualifications on top of the OOW Yacht 30000gt sea service and courses, there is really very little difference compared to the OOW Unlimited. And, unlike a OOW Yacht <3000gt, an OOW Unlimited allows you to progress to Chief Mate Unlimited following similar ‘blended learning’ (HND) and then onto Master Unlimited.

You can also apply for funding to help pay for the qualification.

Apart from the higher standard of education, academic recognition and training provided, there are other significant benefits. You could serve on the largest superyachts, career prospects are improved and not just commercial shipping, but also land-based occupations such as with Flag, Class Societies, insurance, ship management and operations, etc.

It is important to note that currently a Master (Yachts) <3000gt who wants to obtain a Master Unlimited will have to first start with OOW Unlimited and then progress as per MSN 1856 – I have heard that there may be some dispensation following OOW Unlimited for past sea service as Master on a yacht, but this would need to be clarified with the MCA.

For those wanting to serve on Yachts >3000gt, there is also the Marshall Islands (Yacht) Unlimited, but you need to hold a Master Yacht <3000gt and fulfil certain criteria. It is currently only recognised by the Marshall Islands and Cayman Islands registries and restricted to Yachts. This may make sense for those who already have Master Yachts <3000gt, less so for junior officers who have the opportunity earlier in their career to opt for Unlimited certification.

The main challenges I see with the OOW Unlimited pathway are:-

• Self-study – this requires commitment and dedication and may not suit everyone.
• Watchkeeping service for OOW and Chief Mate/Master may be a little more challenging to obtain on some yachts.

Conclusion

For those who want to work on the larger superyachts e.g. 500gt and above, there is no doubt the option of ‘blended learning’ for the OOW Unlimited and Chief Mate Unlimited that allows you to study whilst still working, is a positive development.

With its clear advantages, this pathway is now definitely worth considering by those newly entering the superyacht industry, and by those who may be looking to attain Unlimited certification to further expand their knowledge and career opportunities.

If this is of interest my advice is to do your own research, read the MSN’s, contact the various maritime colleges, obtain the very latest information, weigh up the pros and cons, and then decide which pathway best suits your current and future career goals.

## What Lies Beneath

Although the primary environmental concern challenging our industry is C02 and other emissions generated from burning fossil fuels, there are other vectors such as sewage and grey water that can also have an impact.

Whilst on the larger yachts the new treatments plants take care of both, producing effluent that can be clean enough to use as wash down water, smaller and/or older yachts may not be so well equipped, or have inadequate black/grey holding tanks. Grey water is often simply discharged overboard.

For those of us who have had the ‘pleasure’ of sticking their head into a grey water tank, we are only too aware of the odious and putrid soup that is contained within, in fact, I suggest many crew would rather inspect a sewage tank than a grey water tank such is the assault on the senses. And, given these sensory observations, and the impact grey water can have on tank coatings, why is grey water treated essentially as a harmless liquid?

Whilst the discharge of sewage (black water) is mostly regulated under the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex IV and other national legislation such as United States Environmental Protection Agency (EPA) Clean Water Act (CWA) grey water from ships and yachts is discharged untreated directly into the sea. On yachts, this is very often in close proximity to the coast, beaches, ports and marinas, where there are swimmers or other recreational water users and where it has the potential for the greatest impact on the marine ecosystem.

### So what is grey water?

*If using mobile phone, swipe or rotate screen to see the full table.

Source Grey Water Definition
MARPOL 73/78 Annex V Reg 1 Definitions

4. Domestic wastes means all types of wastes not covered by other Annexes that are generated in the accommodation spaces on board the ship.

Domestic wastes does not include grey water.

RESOLUTION MEPC.219(63) 1.6 Definitions

1.6.1 Dishwater means the residue from the manual or automatic washing of dishes and cooking utensils which have been pre-cleaned to the extent that any food particles adhering to them would not normally interfere with the operation of automatic dishwashers.

1.6.2 Grey water means drainage from dishwater, shower, laundry, bath and washbasin drains. It does not include drainage from toilets, urinals, hospitals, and animal spaces, as defined in regulation 1.3 of MARPOL Annex IV (sewage), and it does not include drainage from cargo spaces. Grey water is not considered garbage in the context of Annex V.

*Note: if in-sink macerators drain into grey water tanks, then the contents and discharge of that tank will need to comply with Annex V.

Clean Water Act, 33 U.S.C. 312(a)(11) Galley bath and shower
Coast Guard regulations, 33 CFR 151.05 Drainage from dishwasher, shower, laundry, bath, and washbasin drains and does not include drainage from toilets, urinals, hospitals and cargo spaces.

So, whilst grey water is well defined, what is less well understood is that untreated grey water contains many undesirable pathogens, organic matter, chemicals and micro plastics (the microfibres that are shed during washing of man-made fabrics) often at levels that can be higher than domestic effluent from sewage treatment plants, and can have an impact on human health and the marine ecosystem.

One of the largest studies on grey water was done by the EPA following a petition in 2000 from Bluewater Network who represented 53 environmental organisations who wanted the EPA to take regulatory action on cruise ship pollution.  The report – Draft Cruise Ship Discharge Assessment Report (EPA842-R-07-005) – was published in 2007 and covered sewage, oily bilge water, solid waste, hazardous waste and grey water.  And, whilst there are significantly more crew/passengers on cruise ships and waste volumes greater, the sources and treatment are very similar to the superyacht industry.

From that study they list common sources and characteristics of grey water in the table below.

Water Source Characteristics
Automatic Clothes Washer bleach, foam, high pH, hot water, nitrate, oil and grease, oxygen demand, phosphate, salinity, soaps, sodium, suspended solids, turbidity

Note: recent studies also suggest micro plastics from man-made fibres are also contained with the waste water.

Automatic Dish Washer bacteria, foam, food particles, high pH, hot water, odor, oil and grease, organic matter, oxygen demand, salinity, soaps, suspended solids, turbidity
Sinks, including kitchen bacteria, food particles, hot water, odor, oil and grease, organic matter, oxygen demand, soaps, suspended solids, turbidity

Note: if food waste from in-sink macerators is draining into grey water tanks this changes the grey water to food waste and therefore discharge must comply with MARPOL V.

Bathtub and Shower bacteria, hair, hot water, odor, oil and grease, oxygen demand, soaps, suspended solids, turbidity

Source: ASCI 2001

Of course, the quantity and quality of grey water varies considerably depending on many factors, such as the number of crew and passengers, the various types of detergents and cleaning products used, personal grooming and hygiene products used by the crew and passengers, and various filters and fat traps if installed.

The EPA study, combined with findings from a previous study by the Alaskan Department of Environmental Conservation – Alaska Cruise Ship Initiative in 2001, found a range of readings of various analytes. A sample of which are found below.

Type Units Av. Concentration Untreated Domestic Water
Pathogens
E.Coli MPN/100mL 292,000
Enterococci MPN/100mL 8,920

*MPN – most probable number

### Pathogens

Untreated grey water contains many pathogens and, in addition to those listed above, can also include, Salmonella, shigella, hepatitis A and E, and gastro intestinal viruses (national Research Council, 1993). Pathogens can pose danger to human health by contact or ingestion of contaminated water, or by consuming shell fish which feed by filtering water.

The 1986 EPA Quality Criteria for Water, commonly known as the ‘Gold Book’, references pathogen indicators and has defined water quality standards based on two activities of import to yachting: marine water bathing and, shellfish harvesting.

From the samples of untreated grey water analysed in the study, the average fecal coliform contamination exceeded the standard of 43 MPN/100mL for shellfish harvesting and, the average enterococci contamination exceeded the standard of 35 MPN/100mL for marine water bathing.

### Chlorine

Although not a major indicator in this study, chlorine is used on yachts in a variety of applications including sanitising fresh water tanks, the discharge of which is generally pumped overboard, often via the grey water tanks, so levels must be carefully controlled so they do not exceed recommended limits.

Studies have found that chronic affects to the marine biota such as poor reproduction and health can be observed at concentrations above 230mg/L with acute effects, severe illness or death, at concentrations exceeding 860 mg/L.

### Oxygen Demand

Organic matter from the grey water acts as food for water borne bacteria. The more food available, the greater the number of bacteria decomposing the waste and using oxygen in the process. Nitrates and phosphorous also contribute to high oxygen demand by providing nutrients for plants and algae to grow quickly, contributing to organic waste when plants die and decompose.

Reductions in oxygen level can be harmful to aquatic species and can, in extreme cases, create ‘dead zones’ where no fish or other organisms can live.

### Dissolved Solids

Suspended solids can affect the clarity of the water and in turn adversely affect the photosynthetic activity of marine biome.

Micro Plastics

This is a more recent and topical concern relating to plastics entering the food chain, consumption by humans, and the longer term environmental and health impacts.

A number of studies have shown that during machine washing of man-made clothing significant numbers of tiny fibres are released into the waste water; and, in the case of yachts, into the grey water tank and eventually into the sea.

One such study is ‘The release of microplastic micro fibres from domestic washing machines: Effects of fabric type and washing conditions’ (Elsevier: Imogen E. Napper, Richard C. Thompson).

This study examined the release of textile fibres during machine washing of clothes from three commonly used fabrics; polyester, polyester-cotton mix and acrylic. The results showed that laundering 6kg of synthetic material could release between 137,951 – 728,789 fibres per wash, ranging in size between 20 𝜇m and <5mm. Given the load on most laundries and, composition of the fabrics washed, one can see the potential for a significant number micro plastics being discharged into the sea on a daily basis.

### Dilution

It is important to note that when grey water is discharged into the surrounding sea it mixes with the sea water and dilution takes place. This effect can be affected by factors such as discharge rate, salinity, water temperature, wind, currents and, of course, a yachts movement.

The Alaska Department of Environmental Conservation (ADEC) concluded that dilution factor would range from approx. 5 to 60 and occur between 1 and 7 meters from the ship (ADEC, 2004). The EPA report suggests that the initial dilution estimated by ACSI and ADEC for a vessel at rest would not likely be great enough for untreated grey water to meet the ‘Gold Book’ standards for fecal coliform and enterococci

From tests conducted by the EPA, it was shown that the dilution effect, due to the movement of a vessel and the mixing by their propellers, for a ship underway between 9.1 and 17.4 knots was a factor of between 200,000:1 and 640,000:1 immediately behind the vessel and, based on those results all ‘Gold Book’ standards for water quality, apart from fecal coliform, would be met.

From this it can be seen there are significant benefits in only discharging when underway and away from the near shore.

Apart from yachts that have advanced waste treatment systems that treat both grey and blackwater compliant with MARPOL IV 9.1.1 and the guidelines in MEPC.227(64) most yachts will be discharging untreated grey water from their holding tanks, often with food waste contrary to MARPOL V, whilst static, directly into the sea. The effect of this can be observed in busy marinas and crowded anchorages on windless days when there is little water movement or seabed disturbance and the water takes on a milky and/or scummy appearance – the difference in water clarity around Cala de Volpe in and out of season is quite striking.

Furthermore, the grey water has the potential for human health risk – depending on contamination levels – especially for those engaging in activities such as swimming, jet ski, wake-boarding, or any other activity where they may ingest seawater or have contact via an exposed scratch or wound. There are also short and long terms considerations related to the marine ecosystem such as algae blooms, bacteria in shellfish, and the introduction of micro plastics into the food chain.

Whilst the issue surrounding grey water applies to commercial shipping as well, due to their sailing and trading patterns they tend to have little impact on inshore waters – as can be seen from dilution effect underway. For cruise ships, if they do not have suitable onboard treatment of grey water, the Cruise Lines International Association (CLIA) members voluntarily agreed to limit the discharge of untreated grey water to when they are underway at not less than 6 knots and at least 4 nm from the nearest land and not to discharge grey water when in port.

### What can we do?

I outline some of the steps could be taken to reduce the impact of grey water discharges.

• As per CLIA, no grey water discharge closer than 4nm from nearest land, underway at not less than 6 knots
• No discharge of grey water in port if facilities available – marinas have work to do here?
• Where available, discharge grey water to suitable reception facilities e.g. barge or ashore
• On new builds, increase size of holding tanks to more practical sizes based on ‘practical’ use of yachts, so discharge can be better managed – including smaller yachts
• Install filters to remove micro fibres from washing machines
• Use ‘environmentally friendly’ cleaning and personal hygiene products – not just ‘ECO or Green’ labeled as these are often-abused and misleading descriptions – carefully scrutinise such claims and check if they have been independently assessed and verified
• On new builds specify and install only black/grey water treatment plants
• On refits, consider updating your treatment plant and include grey water
• Consider dosing grey water with additives that reduce pathogens and/or organic matter
• Avoid using in-sink macerators if the pulp discharges directly into grey water tanks – instead, bag, store and dispose as per MARPOL V
• Installation of fat traps

Some of the above does not require major expense, just a change in operational procedures and, of course, education costs nothing.

The quality of our oceans, and its health are fundamental to yachting – it is the ‘playground’ from which we experience so much pleasure. With our intimate connection to the to the sea we have a responsibility to minimise our environmental impact, protect the long term health of our oceans, and to ensure that future generations get to experience the same pristine seas and diverse marine life that we have all enjoyed.

## How much chain do you need?

I was prompted to write this because of the increasing restrictions in France due to environmental concerns and the impact anchoring has been having on the sea grass/Posidonia. This means that in many places along of the French coast, yachts will have to anchor in water >30m depth.

Although the French rules have perhaps highlighted this, it is not the only place where anchoring in water deeper than 30m is required; other places include Monaco, Capri, the Amalfi Coast, some anchorages in Croatia, Greece and Turkey, the fjords in Norway and Chile and, some of the Caribbean islands – it is not uncommon.

With that in mind, and my own experience of the yachts I have run, I ran a short survey on LinkedIn to gauge how much chain yachts carry.

Although not a huge response, the results were sufficient to mirror my own experience of the amount of chain some yachts carry – in some cases, totally inadequate.

The results to “how many shackles do you carry per anchor?

• Less than 6 shackles – 18%
• 7 shackles – 18%
• 8 shackles – 33%
• More than 9 shackles – 30%

### Rule of Thumb

Of course, there are several ‘rules of thumb’ to help determine how much chain cable is laid depending on the depth of water, among other factors such as type of seabed, weather, current, length of stay, etc. Two such examples are: –

• The International Association of Classification Societies (IACS) – length of chain in Metres = ratio 6 – 10 x Depth of Water in Metres.
• For 30m this would be a minimum of 180m or just shy of 7 shackles.
• The Admiralty Manual of Seamanship uses a formula – number of shackles = 1.5 x √Depth of Water in Metres.
• For 30m this would be a minimum of just over 8 shackles.

With the above figures, if you err on the side of safety, just under 40% of yachts who responded may not have sufficient chain cable to anchor in water >30m depth and, at 35m depth, only 30% of yachts would have the recommended amount of chain. How this compares to the total fleet would be very interesting.

Interestingly, the RYA recommendation is for a minimum of 4 x Depth. For 30m depth only 4 shackles – approx. half of IACS and The Admiralty recommendation. This may be fine for recreational boats, but for superyachts this seems at odds with both IACS who test and approve anchoring arrangements for ships and superyachts, and the experienced seafarers of the Admiralty.

As RYA qualifications are inherent to Yacht Deck Officer training and certification, has their ‘rule of thumb’ become the standard that most superyacht crew use – again an interesting question!

There is no doubt IACS and The Admiralty are a more qualified authority when it comes to anchoring of ships and large yachts and in my opinion captains would be wise to use their ‘rule of thumb’ rather than the RYA.

### The Mysterious Equipment Number

Until I did my Master Unlimited CoC, I never took time to consider how the size of anchor and length of chain were determined for a given vessel. That’s when I learnt about the Equipment Number (EN).

Most superyachts are Classed by one of the IACS members such as Lloyds, DNV GL, ABS, RINA, etc., and they use common rules to determine the mooring equipment. This is based on the EN which is calculated for every Classed vessel – the formula is as follows: –

EN = ² ⁄ ³ + 2 BH + 0.1A

Where:-

• = moulded displacement in tonnes to Summer Load waterline
• B = moulded breadth, in metres
• H = effective height, in metres, from Summer Load waterline, to top of uppermost house
• A = area, in square metres, in profile view, of the hull, superstructure and houses above Summer Load waterline.

The resulting EN is used in a table that details the number and mass of the anchor, chain length, diameter and grade, as well as towing and mooring lines.

Excerpt from Equipment Table – note ‘Total Length’ of chain is normally split equally between the two anchors.

It is important to note that the EN and anchor equipment is based on the following assumptions and limitations:-

• Temporary mooring in harbour or sheltered waters
• Current velocity: max 5 Kn
• Wind velocity: max 48 Kn
• No waves
• Length of chain paid out, scope 6 -10
• Good holding ground

The effect of waves is important – a significant wave height of just 2 metres would reduce the equivalent max current and wind velocities as follows:-

• Current velocity: max 3 Kn
• Wind velocity: max 21 Kn

A significant reduction in the holding power.

As most yachts use high holding power anchors (HHP) the rules also allow their mass to be reduced to not less than 75% of the table value.

### Bitter End – Caution!

It is also important to know that the pin securing the bitter end to the chain locker is designed to be sacrificial and break at a load between 15% – 30% of the minimum breaking strength of the chain cable – it is designed to fail to prevent structural damage to the vessel.

It should be a fundamental part of the yachts risk assessment and procedures that, in the event of a runaway chain, the mooring team evacuate to a safe area as the flailing end of an anchor cable can have devastating effects – as was sadly experienced on Ocean Victory.

The anchor and mooring arrangements need to be carefully designed for the risks involved; unfortunately, some yachts, especially those with enclosed decks, place the windlass operator in harm’s way and do not provide safe egress in the event of a failure. Like many operational aspects of yacht design, work is still required to improve safety.

### A Guide to Anchoring

The video ‘Anchor Awareness’ produced by DNV, GARD and The Swedish Club, although based on commercial ships, is also valid to larger yachts and is a useful resource that helps demonstrate anchor procedures and safe practice and is well worth a watch – especially for junior officers and deckhands who may be part of the mooring team.

Can be accessed by taping on the image below.

This piece was not meant as a guide to anchor best practice, but to try to assess if yachts carried sufficient chain for the intended depth, and help fill in some of the knowledge gap that may be missing from the yacht syllabus.

I hope it imparts a better understanding of how anchor and chain cable size and length are determined for yachts. And, importantly, the amount of chain paid out relative to depth that is recommended by authoritative bodies.

This knowledge may result in more secure anchoring and the provision of chain more appropriate to the expected use, water depths and conditions that may be encountered.

## I can sleep when I’m dead

I suspect many captains and crew will have succumbed to the embrace of this maxim – I know I have in my past.

Working long hours and having minimum sleep was often worn as a badge of honour, it demonstrated a grafter, someone who was willing to put in all the hours necessary to get the job done. But as research has now shown, sleep deprivation, whether acute or chronic, can have short term consequences – sometimes devastating – as well as long term physiological and/or mental health effects.

I was somewhat aware of the importance of sleep and things such as the circadian rhythm, but it was only recently after reading ‘Why We Sleep’ by Mathew Walker, who is currently Professor of Neuroscience and Psychology at the University of California, Berkeley, that I began to really appreciate why sleep deprivation can be so damaging to not just health, but also performance and safety.

The book details the reasons why we sleep, what happens during sleep, the benefits of sleep and the effects of disruption and/or deprivation. Like the air we breathe, the water we drink, and the food we eat, sleep is essential to our health. The Guinness Book of World Records happily records extreme activities such as a freefall from 41,422 metres and other events such as tight rope walking across the Grand Canyon without safety net or tether but does not recognise sleep deprivation records because of the danger to health!

### What’s this got to do with yachting?

The World Maritime University (WMU) Report1 into the hours of work and rest (HOWR) in shipping also considers this subject and the effects of lack of rest, fatigue, safety and well-being of crew and these issues are equally applicable to yachting.

We know that the demands on crew have been increasing for many reasons and, in the main, there has not been any real change in the manning levels to meet that demand and on many yachts, it is likely that the quality and quantity of sleep is suffering as a result. Compounding the potential for sleep disruption are the variable work patterns that are an operational characteristic of yachting as the program and use changes e.g. guest-off, guest-on, daywork, watches, late finishes and early starts, even if crew are maintaining their HOWR.

Consider that the HOWR minimum rest period should not be less than 10 hours, but can divided into two periods, one of which not less than 6 hours. And that within that time there are factors such as eating, socialising, waking and preparing for work, that eat into sleep time. If working to the minimum regulations the longest period of sleep could be less than 5 hours – less than the amount research suggests is optimal.

I’m sure we all know how bad we can feel for days after a long-haul flight, yet crew are often expected to switch from working during the day to night at short intervals. Studies have shown it takes a day per hour of time zone difference for the body to acclimatise. It would take days for a crewmember assigned to work a night watch to properly adapt and perform at their best and they would likely be feeling the undesirable effects when they switched back to daywork at the end of the week – when they would have to go through the whole process again.

The working pattern and allowing sufficient time to acclimatise to the working hours is an important factor in helping with sleep and fatigue. I know in the past we used to rotate deckhands onto night watch once a week and stewardesses would frequently switch from late nights to early morning with the result their body clocks where probably always jet lagged. Having a schedule that allows acclimatisation to working hours is not an easy task given limited crew and variable demands but, where practical, it warrants a more considered approach.

Of course, it’s not just the work pattern that can disrupt sleep. The environment, such as noise and light, can affect the quality and quantity of sleep. Noise from being underway, picking up and dropping anchor, bow thruster operation, light from portholes or crew entering the cabin. And as we all know, the violent motion and noise of a yacht in rough weather also can severely disrupt sleep.

Crew accommodation and cabins are also a factor. Having somewhere free from noise and light pollution, with a comfortable ambient temperature, can be a challenge on some yachts, especially the smaller yachts where space is severely limited and often the crew mess and laundry are in the same space. Though, even on some larger yachts, the crew cabins can sometimes seem like an afterthought.

Minimising noise and light – beyond the minimum MLC standards – should be a priority such as: –

• Black out blinds for portholes
• Curtains around bunks that can also block light and afford some privacy
• Low intensity lighting for crew corridors
• Better sound insulation – especially crew corridors and where cabins back onto the crew mess or technical spaces
• Improved isolation of equipment; resilient mounts, sound boxes.
• Doors at corridor ends
• Carpet with underlay in cabins and corridors

Some of the above could be applied to existing yachts.

For those who believe they can manage on minimum sleep, it is interesting to note, though not scientifically proven, that Ronald Reagan and Margaret Thatcher, two of the most well-known exponents of 4 – 5 hours of sleep, suffered in later years from Alzheimer’s. The point being, perhaps the cumulative effects of restricted sleep may be more profound than we might think.

Unlike shipping, our industry is not driven by commercial pressures but by more esoteric metrics such as pleasure, enjoyment, quality, safety, and security, all of which are heavily reliant on the crew. Yet often yachts are designed to comply with the minimum standards rather than the operational realities of delivering incomparable experiences to yacht owners and/or charter guests.

The ‘WHU Report’ and ‘Why We Sleep’ should be essential reading for anyone involved in the design and operation of a superyacht. They offer compelling reasons why better sleep can result in happier and healthier crew, better performance, safer yachts and why it deserves more attention in our indusrty.

## Is it possible to ‘future proof’ a superyacht?

The reason for this question is that it doesn’t take much to realise that being able to switch your yacht from fossil fuel to green fuels in the future will have a positive impact on use, cost, and asset value.

Whilst these concerns and the transition away from fossil fuel seems to be far away, the impetus is growing and the reality is that when you take into account the design and build cycle along with the lifetime of a superyacht, you begin to understand why this may be an important consideration for anyone investing in a new build today.

Indeed, Lurssens recent announcement of a project using methanol and fuel cells may represent a paradigm shift for the industry. Though there are still questions about the availability of green methanol and storage and bunkering, this is probably the only superyacht in build that has the potential to adapt to a zero emissions future.

From discussions with other shipyards, it is clear that the environment is becoming an important consideration for some owners, and the pressure to act will only become more intense in the coming years.

The current narrative seems to be that ‘hybrid’ or ‘diesel electric’ (propulsion from electric motors) will allow you to simply remove the generators, replace them with a stack of fuel cells and then load up on green energy. On the surface these seems to make sense, however I think reality may be a little different.

When you look more deeply at the how, the challenge will not come from the replacement of the generators, it will come from the availability and choice of the green energy carrier that replaces the diesel fuel.

Currently hydrogen, methanol and ammonia seem to be the leading fuels in the drive to zero emissions shipping. LNG and biofuels also provide a useful pathway that helps reduce emissions but are unlikely to be the long-term solution.

The production of green ammonia or methanol, also known as ‘e’ fuels, require hydrogen produced via electrolysis using nuclear or renewable electricity and synthesis with air (e-ammonia) or CO2 (e-methanol). It is a very energy intensive process and methanol also depends on the supply of green CO2 e.g. biomass or direct air capture (DAC).

Due to the amount of energy required to produce these fuels and supply chain costs, these fuels are likely to be more expensive than today’s diesel. Technology and innovation in all its forms will still be necessary to reduce energy consumption.

Worth noting is that hydrogen, ammonia, and methanol, can be used in internal combustion engines (ICE). For example, the Ro-Ro/Pax carrier, Stena Germanica was successfully converted to run on methanol. This could provide another pathway for us; though I don’t know if these ‘gas’ or ‘dual fuel’ ICE’s are suited to superyachts? Maersk has also announced the building of a ship to run on methanol, whilst acknowledging that they are not entirely sure of fuel supply or infrastructure – I think it demonstrates a leadership that may help break the supply/demand impasse and drive change.

The major challenge with all these fuels for yachts, where space and aesthetics – a cryogenic hydrogen tank on the aft deck would not be ideal – are major factors, is that they are less energy dense than diesel, require more volume for the same amount of energy, along with special storage and enhanced safety due to the nature of the fuels e.g. flammable and toxic.

More information an be found in The International Maritime Dangerous Goods (IMDG) Code, International Code of Safety for Ship Using Gases or Other Low-flashpoint Fuels (IGF Code) and IMO MSC.1/Circ.1621 Interim Guidelines For The Safety Of Ships Using Methyl/Ethyl Alcohol As Fuel.

This excellent diagram of Volumetric and Gravimetric energy of various fuels from DNV-GL – Comparison of Alternative Marine Fuels, Report No: 2019-0567, Rev. 3, clearly highlights the energy differences.

##### Energy densities for different energy carriers (inspired by /49/ /72/ and /73/ of the report). The arrows represent the impact on density when taking into account the storage systems for the different types of fuel (indicative values only)

Hydrogen, due to the storage requirements, compressed or liquid, probably excludes its use directly as a marine fuel on superyachts though, as with shipping, it may be well suited to coastal cruising. Much more likely, as with the Lurssen project, is that methanol or ammonia is used as the energy carrier and converted back into hydrogen using reformers onboard if fuel cells are used.

The resultant hydrogen would then be used in Proton Exchange Membrane (PEMFC) or High Temperature Proton Exchange Membrane (HT-PEMFC) fuel cells. HT-PEMFC are less critical on the purity of the hydrogen and the heat can be used to improve the overall efficiency – though, to date, as an industry we have not been very energy efficient with the use of waste heat from engines or generators.

Although solutions for the storage, ventilation, safety and bunkering of methanol and ammonia will no doubt be found – it’s already carried onboard ships either as a fuel or cargo – how this is integrated into the hull of a superyacht may have some significant impacts on space, layout and, of course, range.

I think some caution is required before promoting the use of ‘hybrid’ or ‘diesel electric’ as ‘future proof’ solutions. We need to be able to demonstrate how this would work, the practicalities and impact on cost, safety, use, space and range to name just a few considerations. This will be crucial to the future growth of the industry as yacht owners and their advisors will need to weigh these factors in their decision-making process.

Finally, Lurssen and their visionary customer, may have found one pathway that helps answer the question. That is a real benefit to the future of the industry.

## A Culture of Adjustment…Hours of Work and Rest

I must admit to a bit of plagiarism here as the title, in part, comes from the World Maritime University (WMU) Report1 into the hours of work and rest (HOWR) in the shipping industry – link at the bottom. When I saw the title, read, then reflected on its contents, it became clear there were parallels with the superyacht industry.

That being said, it is important to recognise that in the superyacht industry the issues surrounding misrepresentation of HOWR are generally limited to the peak periods; those times when guests are onboard when, due to a combination of high demands and insufficient crew. To successfully navigate the obligations and intent of the legislation it is important to fully understand the regulations. The alternative is creative application of HOWR – something I am sure that most yacht captains and crew will have experienced.

In my early days on yachts, working long hours to deliver the guest experience was the norm and just part of yachting. “Harden-up” was often the refrain when someone spoke out on fatigue. It was like the measure of a job well done and validation that yachting was for you. Hours of work and fatigue were given very little attention and remained undocumented; unless you were crew you had no idea of the extent of the problem. Over subsequent years, regulations such as ISM and MLC were introduced to improve vessel safety and pollution prevention and the health and welfare of crew – less about yachting and about preventing the abuse of crew that was prevalent in some sectors of the shipping industry.

### Some Reasons

Unfortunately, as the WHU report suggests, despite the regulations and a greater appreciation of fatigue and its consequences, there is still a culture where work hours are, either under reported or adjusted to facilitate compliance. There are many reasons given, many of which are analogous to the superyacht industry:

• Legacy – it’s part of the ‘can do’ attitude that is prevalent within yachting; the desire to deliver the best experience for the owner or guests.
• Manning – having an appropriate manning level to meet the diverse demands of the operation; not just ‘minimum safe manning’ which is often the metric.
• Contemporary Yacht Operations – yachting has evolved and so have the demands on crew, not only from owners who expect greater levels of service and experience, but also from the administrative burden that is a consequence of both regulation and management company reporting systems. Manning has failed to keep pace with this and something OnlyCaptains alluded to in this piece – Manning A More Considered Approach Required
• Cost – crew are one of the highest costs of yacht ownership and so it is understandable that advisors and yacht owners are driven to reduce manning.
• Financial Incentive – charter tips or bonus.
• Employment Security – whether it be the Captain responsible for the yacht compliance, or an individual crew member not ‘towing the line’ there are concerns about the effect accurate reporting may have on employment prospects.
• Management Pressure – either directly or indirectly they send signals that encourage the misrepresentation of HOWR.
• Stakeholder Distance – the physical and psychological distance between the various shore-based stakeholders and the operational crew, means there is often a limited understanding of the work that crew do and what it takes to deliver an exceptional yachting experience, day after day.
• Lack of Effective Controls – as proven, it is relatively easy to under report or adjust HOWR, even on some electronic systems, to ensure compliance. The fact that these are not identified by internal audits, Flag or PSC suggests the current inspection and enforcement mechanisms are not fit for purpose.

Also, in yachting due to the cyclical nature of demands ‘guest on vs. guest off’ there is also an attitude of:

What’s the big deal, the crew get plenty of time to rest when we are not onboard.

The reality is often very different; there is still plenty of work to be done that is critical to maintain and protect the value of the asset, safety considerations, and to ensure the yacht and crew are ready for the next visit.

### Rest and Fatigue

This leads onto ‘Compensatory Rest’ as allowed by MLC, to mitigate or justify non-compliance; often the rule rather than the exception. Unfortunately, this is not always practical due to a yachts program e.g. short turnaround for next guests (back-to-back guests/charters) repositioning in rough sea, etc. And, unless the compensatory rest is both, timely and adequate, it will not prevent fatigue and its consequences.

There are numerous studies on fatigue; searching ‘fatigue and its effect on performance and safety’ in Google (other browsers are available!) produced 1.5 million hits – I would hazard a guess that none of the results would praise its health and performance benefits!

It is recognised there are three types of fatigue:

• Transient fatigue this is acute fatigue as a result of sleep restriction or extended hours awake within 1 or 2 days
• Cumulative or chronic fatigue brought on by repeated mild sleep restriction or extended hours awake across a series of days.
• Circadian fatigue refers to the reduced performance during night-time hours, particularly during an individual’s “window of circadian low” (WOCL) -typically between 2:00 a.m. and 05:59 a.m.

Research has also shown that the accumulation of sleep deficit e.g. having an hour less of sleep for several consecutive days, needs a series of days with more-than-usual sleep for a person to fully recover from cumulative fatigue.

This suggests that, very quickly into a busy guest period, crew may already be affected by fatigue; their cognitive ability impaired, decision making and judgement clouded, and performance impacted. Many studies compare fatigue to the effects of alcohol consumption, the last thing anyone would want would be crew behaving as drunks due only to sleep deprivation.

Adding to the problem is that many crew cabins are cramped, poorly designed, and suffer from light and noise pollution, these factors, along with the yachts motion, even at anchor, can all affect the quality of sleep – another area worth consideration?

The shipping industry is aware of fatigue and has contributed to the canon of research on the subject, these include The SEAFARER FATIGUE: THE CARDIFF RESEARCH PROGRAMME, MCA MGN 505(M) and IMO GUIDELINES ON FATIGUE (MSC.1Circ.1598) and are all well worth reading.

Interestingly, in 2006 when the Cardiff Research Study was published, one conclusion was:

This study shows the current method for recording and auditing working hours is not effective and should therefore be reviewed.

Seems not much has changed.

As I discovered, honest reporting of HOWR comes with a cost, unless you have a supportive management company and yacht owner, so I fully appreciate why some captains might be reluctant. However, unless we report HOWR accurately we will remain part of the problem and there will be no incentive to change.

If you always operate at max, like an engine constantly run in the red zone, something will break sooner rather than later!

Ultimately the reason why there may be a need to under report or adjust of HOWR is that, in many cases, there is insufficient crew for guest periods. And, this is after all when a yacht owner, their family and friends or charter guests get to experience the enjoyment of yachting.

### A Contempoarary Problem

Far from this being restricted to older yachts, this remains a contemporary issue, with some recent prominent examples shown not to have enough crew to deliver consistently the full range and standard of services demanded by yacht owners and charterer guests – this does beg the question; who is advising the owners and how did they assess the manning levels?

In response, I like to reflect on a comment from a respected designer Carlo Nuvolari, of Nuvolari Lenard, when he stated in an interview in Boat International – Nuvolari Lenard discuss the problem with yacht design 18 November 2015 by Stewart Campbell:

A Lot – Not All, But A Lot – Of Our Colleagues Don’t Go On Boats. I Can’t Understand It.

Perhaps ‘a bit tongue in cheek here’ a solution would be for every designer or advisor, to spend at least one season working on a busy yacht in all departments, before they are allowed anywhere near a prospective yacht owner and/or its operation…just a thought!

And, whilst we can address the problem with more careful consideration of manning on new-builds, clearly, we cannot re-build each yacht and the demands will not decrease…so what can be done?

### Searching for A pathway

Apart from accurate reporting, Captains will need to look at every aspect of their operation and work schedules to find efficiencies and/or time saving solutions e.g. use of a standing shore team that speeds up turnarounds. Yacht management working with their captains to improve SMS and operational reporting, using technology to make the systems more user friendly and efficient. And, where practicable, directing much of the administration back to shore management, freeing Captains and crew to be the operators, focused on ensuring the yacht owners, their guests and charterers are the priority.

Final thought. Would you fly on a long-haul flight if the captain (eyes darkened by fatigue) was trying to finish the plane’s budget, next maintenance schedule, organise his parking at the next airport and was on the phone interviewing a cabin attendant as you boarded? I think the answer is obvious, so why do we run our yachts this way?

## Crew Rotation In the Superyacht Industry – Part I

Although commercial shipping has rotated crew for many years, it is a recent phenomenon in the superyacht industry. It started to become a reality on yachts first with engineers, and then on the larger yachts where manning regulations required officers with STCW qualifications.

When rotation first started is a little unclear; it was certainly in use in the late 70’s when I was with BP Shipping – though it only applied to deck and engineering officers. However, what was clear, that it was not born out of regulation, but driven by market forces and a recognition that to attract and keep the right people they had to offer a better work/life balance. Today, these very same reasons are relevant to yachting.

So, in our latest post, we are going to take a dive into rotation and, due to its importance to many captains, their families and yacht owners, we will break it down into two parts and focus on the whys, how’s and the impact this fundamental employment change has had on the yachting community.

This week in Part I, Brendan is writing of his own employment journey to supply some context, then next week in Part II, Malcolm will take a deeper look at the pros and cons and how you might present the idea to a yacht owner using a worked example.

### Brendan

I entered yachting when contracts and structured leave were rare to the point of not known. Leave was when it suited the yacht’s programme, often with little notice. Crew would scramble to make last minute arrangements when a window opened. With limited leave, weekends in port was our time to get away, explore and socialise, leaving the yacht to the care of a couple of watchkeepers. Regardless of age or relationship status, life revolved around the yacht and no alternate lives ashore were maintained.

This began to change for me in 2007 when I joined my first 100m+ yacht and realised there was no stopping a yacht of this scale. It needed crew every day to keep the show running and there were no more ‘weekends with a couple of watchkeepers’. I remember naively saying to the Heads of Departments we would shut the yacht down one weekend for everyone’s rest; they humoured me, said yes, but ignored the instruction and kept the yacht working the way it demanded.

Since that time, I have modelled many and various employment structures for yacht owners and their representatives. When I do these, I do not speak of rotation from a crew’s perspective, it is with consideration of the yacht owners needs and their investment. My point being that the yacht, the owner and guest experience should not suffer because of crew taking leave. I support this position with a crude calculation; add the finance cost of the yacht to the operating expenses and divide by 365 to gain the cost per day of the yacht’s existence. The number can be staggering and to think that you would intentionally stop the operation so the team can take days off does not show good value.

Further to this crude calculation, the owner is reminded that the beauty of yacht ownership is freedom and spontaneity. Rotation can allow that when a gap opens in their diary, they can escape to their yacht and enjoy the pleasure of being on the water with family and friends; something that is even more relevant today.

In one of the presentations the yacht owner agreed for senior crew without hesitation, saying, “but yes, they have families, and we want them to be focussed on us when they are here and not worried about when they can get home.” For junior crew there was a different perspective with the principal asking, “why do these crew want so much time away when they were young?” Weren’t these the years to earn money, travel and gain experience needed to progress?

Malcolm’s comment – the latter point I also heard from an owner. One 80m+ example lost several junior crew because of generous leave/rotation! The basic reasoning was it was expensive to spend so much time at home, all their friends were working so no one to hang out with, and it took far longer to gain the necessary sea time and experience to progress. Sometimes you cannot win!

### Be careful what you wish for.

Since 2007 (outside of shipyard construction) I have been on equal time rotation. This is a Nirvana for many but, having defended the position to the owner that the yacht requires 365-day attendance from its captain and senior team to get rotation over the threshold, you are accountable to work accordingly.

So now, during a 2-3-month roster onboard, I tend to focus completely on the yacht and my days exploring the wonderful areas I sail through are a distant memory. Crew come and go in and procession of rotational changes and although bonds are still made perhaps, they are a little weaker? That said, when they return refreshed, the faces are familiar and they quickly adapt back to life onboard without missing a beat; ensuring operational readiness, a consistent service quality, better maintenance and safety.

It could be said that with better leave and rotation means the yacht is now the place we work; it is no longer the centre of our universe and the place where we also lived our lives!

Clearly this is a much healthier balance but, occasionally, I do look back on those time long ago in sepia, when spending 11-months of the year with the same tight crew created my most memorable experiences and learning opportunities. I am open in saying my memory is grander than the reality, it was unsustainable if I wanted any sort of normal life outside of yachting. I could not have raised a family without rotation and so today I am content with a few laps around the yacht at anchor or a quick morning run on the rare times in port. My days exploring are not lost, I now have the time and freedom to return to destinations in my own time and with my family, and that is incomparable.

Done right, better leave and rotation offer crew and yacht owners many benefits and, although there are added costs, carefully planned, they are not as high as might be imagined, and there are many advantages that cannot be measured purely in monetary terms that can add value to the yacht owning experience.

In Part II Malcolm’s deep dive is where you need to go to look to the tools that you might need when structuring your own rotational plans to a yacht owner, their representative or yacht manager. The strength of your case will depend not only of the financial model, but also the quality of your reasoning and supporting facts. Without a compelling case, the yacht owner or their representatives might be thinking “living the dream, sailing the seas, working half a year and still complaining?

## Measuring Yacht Efficiency – How And Why It Matters

Last week, I attended the Yacht Cub de Monaco: Capital of Yachting Experience. It was a very well organised and attended event, with some very interesting presentations and discussions.

It was also the launch of the Yacht Club de Monaco Superyacht Eco Association (SEA) INDEX. Supported by Nobiskrug and Credit Suisse, this is an important initiative with a goal to benchmark yachts in terms of their CO2 environmental performance. And, whilst there are other emissions, CO2 is by far the largest greenhouse gas (GHG) of importance and the one most visible in the public eye.

The principle is that it uses the IMO’s Energy Efficiency Design Index (EEDI) formula with a few changes to make it more specific to yachts.

The SEA INDEX is the first tool designed to assess and compare the efficiency of a yachts design and its environmental impact in terms of CO2, with a transparent and easy to understand rating system. Stars are awarded from 1 (lowest rating) to 5 (highest rating) depending on where a yacht sits above or below the rating bands relative to the baseline of sampled yachts.

Image: Courtesy of the SEA INDEX

The data from approx. 130 yachts of various length and displacement was sampled and their data entered in order to develop the initial baseline – there are now over 200 yachts.

It uses max power and speed, which may seem excessive, but a metric was required and, if you consider this as the ‘maximum emissions potential’ of a yacht, by using the same set of data points for all yachts, it provides a ‘standard’ for comparing their designs. For example, on comparable sized yachts, a more efficient hull will require less power for the same speed, and more efficient HVAC and hotel systems power management, will require smaller generators, both of which will result in reduced emissions and a higher INDEX rating.

And, as new designs and engineering innovations are introduced into yachting, the SEA INDEX will help highlight the improvements being made.

Of course, actual emissions depend on many variables that are affected by an owner and the operational profile of a yacht – these are hard to assess in any consistent or meaningful way. If we had recorded all yacht activity and consumption over the last 10 or 20 years, we would be able to draw a curve of standard deviation and have an idea of what might be described as ‘average use’ on which to make comparisons. Unfortunately, we don’t have this information, and this is perhaps the flaw in all such tools, so the only true account of a yachts CO2 emissions has to be calculated from their fuel consumed.

The factor the IMO use for CO2 emissions from MGO is 3.206, this means for every 1,000t of MGO used, 3,206t of CO2 is generated so it is easy to calculate your CO2 from fuel.

Any design efficiency gains, and improvements that can be made in the operation of the yacht, such as running at lower speed, managing power, switching off unused lighting and equipment, etc., will reduce the power required, fuel consumed and emissions.

In combination with efficiency gains, Carbon offsetting is one way to mitigate a yachts emission. Though, as I have written in a previous piece Superyacht Carbon Offsetting great care is required to select one that is fit for purpose.

But, it’s not just the amount of CO2 that is an important consideration. Looking to the future, it is very likely that shipping, like other industries, will be impacted by Market Based Mechanism’s (MBM) to drive forward the transition to a greener future, and these will have cost implications.

The IMO by 2023 will introduce their new framework for the reduction of GHG emissions from shipping and it could include a carbon tax. The EU in a recent plenary session of parliament, agreed that shipping should be included in the EU Emissions Trading Scheme (ETS) possibly in 2021and include vessels less than 5000gt. Trafigura, one of the World’s largest ship charterers, published on 25th September “A proposal for an IMO-led global shipping industry decarbonisation programme” calling for a $100 –$200 tax per ton of CO2 on shipping as the only way of driving the necessary industry change.

As further evidence of the direction of travel for CO2 emissions for business, Swiss Re made this announcement on the 15th September 2020:

“Swiss Re steps up its internal carbon levy to USD 100 per tonne as of 2021 and will gradually increase it to USD 200 per tonne by 2030”

Any such taxes or levies imposed on CO2 emissions will increase the cost of yacht ownership.

On top of that we have Environmental Governance and Sustainability (EGS) targets that are becoming ever more prevalent, especially in investment and finance. The Poseidon Principles is just one initiative, launched the 18th June 2019, “major shipping banks will for the first time integrate climate considerations into lending decisions to incentivize maritime shipping’s decarbonization” their goal is to work towards the IMO 2030 and 2050 reductions in GHG by ensuring that their loan books are aligned with those targets – finance will become harder for vessels that fail to meet efficiency improvements and GHG reductions.

Could similar lending rules apply to yachts in the future, how would that affect the value of older less efficient yachts?

Whilst it is not yet clear how taxes and regulations will be imposed in the future, what is clear, is that yachting is unlikely to escape their embrace. And our intimate connection to the sea and the environment places additional responsibility on the industry to protect the health of our oceans and planet. The SEA INDEX is the first of many important tools, including those from the Water Revolution Foundation, that will help us to understand our environmental footprint and drive the necessary change that puts us on a pathway to a sustainable superyacht industry.

Like any instrument that is reliant on data; the more yachts that participate, the more refined and accurate the SEA INDEX will become – I would call upon all Captains to get involved.

## Superyachts – A Question Of Manning

When I was asked to write a piece on Minimum Safe Manning (MSM) and how it affects yacht operations for the Superyacht Report, I knew that, although an important factor, it was only one of a number of considerations used to determine the crew complement. However, what was also clear, is that many yachts do not have sufficient crew to meet the expectations and demands of their owners and guests. A point that was recently expressed in article from the International Superyacht Society (ISS) Captains Committee, where they raised concerns about fatigue and its dangers, and asked:

Why is it that manning levels that were appropriate years ago are still accepted as the norm today?

From my own experience I can empathise with this.

Some time ago I took command of a yacht owned by a lovely family with a large family residence serviced by what seemed like an inexhaustible number of staff. For them, they were used to having the most attentive service 24 hours a day and had the same expectation for the yacht. They built a beautiful yacht that could carry up to 22 passengers which, she often did, but unfortunately was manned with the same number of crew as an equivalent 12 passenger yacht. As might be expected, it created significant challenges!

Following that experience, I also had the opportunity to review three new build PYC yachts and their manning. My observation on all of them, was that there was insufficient crew, partly because PYC compared to LY3 required additional MSM numbers, which impacted on the hotel side, but also due to the number of guests carried and services expected. After delivery, two ended up building more crew cabins – imagine the expense – and one downgraded to LY3 because they could not meet the MSM requirements without negatively impacting on the interior service. Clearly, if it was so obvious to an experienced mariner, why was it not obvious to the broker, designers and the shipyard?

The suitable manning of yachts is not restricted to large yachts either; there has been numerous discussions and articles written about crew on various sizes of yacht having to be ‘creative’ with their hours of work and rest in order meet owner/guest demands and remain compliant.

I suspect that many readers who have worked on busy yachts will have all had the same experience, where the team spirit, professionalism and commitment of the officers and crew to deliver the very best experience, overrides concerns about fatigue and the effect on performance, welfare, mental health, safety and crew retention.

So how are manning levels determined and, how can they be better understood?

### Considerations

Along with the MSM (more of which below) there are other factors that normally determines the size and makeup of crew:

• Finance is an important consideration as crew expenses are amongst the highest operational costs so obviously it makes sense to optimise manning
• Manning levels on similar sized yachts are used as a comparable standard, especially applicable to production yachts
• Given the high value of the yachts ‘real-estate’ owners, understandably, will want to maximise owner/guest accommodation – the luxury spaces
• Technical, service, access and operational spaces also require a large volume

Additionally, some in the industry may be keen to gloss over crew numbers to help with a sale, they may fail to manage the owners expectations or, just do not possess the operational experience to understand the numbers needed for a particular owner and yachts operation.

Once the above factors are considered and the various spaces assigned, the crew accommodation is designed following the Maritime Labor Convention (MLC) guidelines and the number of cabins/berths can be defined. Interestingly, MLC may actually be having some unintended consequences; as one respondent – maybe controversially? – in the ISS article suggested:

What we need is more berths not more space!

### Minimum Safe Manning

A commercial yacht will require a Flag state approved MSM – many private yachts, as with other regulations, may also choose to comply on a voluntary basis.

An owner/operator will make an MSM application based on Flag guidance and the IMO Principles of Safe Manning Resolution A.1047(27). Once approved, an Administration will issue an MSM certificate, however, this is only the minimum number of crew (those requiring STCW or equivalent qualifications). This is the captain, deck/engineering officers and ratings and, cook, depending on crew numbers and Flag requirements, necessary to safely operate a yacht when it proceeds to sea:

The ship named in this document is considered to be safely manned if, when it proceeds to sea, it carries no less than the numbers grades/capacities of personnel specified in the table

This does not include the hotel team; service, housekeeping, laundry and galley, or the additional deckhands necessary to launch tenders, run the water sports, etc., or other specialists required these days – these are all additional to the MSM.

Of note is that the A.1047(27) changed from previous resolutions as follows:

A.890(21) and amendment A.955(23)

1.1.1 maintain safe navigational, engineering and radio watches in accordance with regulation VIII/2 of the 1978 STCW Convention, as amended, and also maintain general surveillance of the ship;

A.1047(27)

1.1 maintain safe navigational, port, engineering and radio watches in accordance with regulation VIII/2 of the 1978 STCW Convention, as amended, and also maintain general surveillance of the ship;

As you can see, safe manning in port was added but, so far, I have not seen any yacht specific guidelines on ‘port’ safe manning – commercial ships are normally involved in cargo operations so they tend to be more fully manned in port. In-port-manning can be a difficult issue for captains; it is often left to them to determine and they have to strike a fine balance between safely manning the yacht and providing crew valuable shore leave but, given number of incidents and fires in port, perhaps it should be better regulated? Running drills with reduced crew will help identify what is a safe number.

Often the Manning Scales provided by an Administration will be used as the standard. However, they allow some latitude on numbers based on the strength of the application and, operators can also take advantage of manning reductions allowed due to ‘distance from safe haven’ – which, for yachts, seems contrary to their operational demands?

Once the MSM has been agreed the rest of the crew can be determined – if the total number of berths is 15 and the MSM is 8, that leaves 7 berths for the rest of the team.

### Three Hundred and Sixty Degree Approach

As can be expected expect this approach produces mixed results – a bit like the ‘off-the-shelf’ budget that so often disappoints.

What is necessary a three hundred and sixty degree approach; an in-depth assessment of all the factors and how each unique owner wants to use their yacht. Only once armed with that information can you estimate the right manning levels and/or manage expectations by modelling the expected demands, peaks and crew work schedules.

The point of managing an owners expectations is key, especially in the case of production and semi-production yachts where crew accommodation/berths tend to be fixed. In these circumstances it is still important to make the assessment. This helps avoids frustration and disappointment by communicating any limitations that may surface, along with possible solutions, such as use of external laundry services, shore-based crew, or shadow boat, at the earliest stage to an owner.

Yes, the yacht can operate with these crew numbers but, the service onboard will be limited in these areas…is that what you want?

Making a proper assessment requires effort and collaboration; asking questions, getting to know an owner, how they expect to use the yacht and the style and depth of services that are important to them.

### YACHT B

• Likes quiet time with wife and one or two guests • Meal times, silver service and large and varied selection
• Rises late goes to bed early • Has boat full of family and friends
• Likes to be in port as often as possible • Likes to party and stay out late
• Eats very light diet and at strict times • Loves to be at anchor
• Guests have to follow his rules • Some guests rise early late, others rise late and bed late – no rules set for guests
• Wants very light touch and informal service • Love water sports, all the toys setup and available
• Happy to help themselves • Tender rides for sightseeing, shopping trips, etc.
• Doesn’t want fuss • Wants a masseuse available
• Just love being on the yacht • Expects crew to look after children
• Wants formal service at all times – loves the attention and show
• Will not help themselves and expects stewardess on call 24/7
• Often invites friends over for drinks/meals at short notice

On both (A) and (B) the normal crew complement was 19. The manning on (A) worked well, but on (B) we were unable to deliver and maintain the standards of service expected and without being non-compliant. Fortunately, the owner was understanding and pragmatic and, after detailing the issues and possible solutions, it was agreed that we would use two guest cabins for 4additional crew that allowed us to provide the level of service that was important to him. Later, the the yacht was modified and 2 additional crew cabins (4 berths) were added at considerable expense.

Understanding use and gathering information similar to the above example will help to determine the appropriate manning levels, especially during those important peak times in guest operation, and allow you to develop work schedules for all crew and each department. It may need several iterations and some finessing to get right but this is a crucial exercise as it provides the information necessary to have a meaningful discussion about manning with an owner.

### Operational vs. Standby

Unlike a commercial ships where workload and manning is more easily determined and manage accordingly, yachts are a much more difficult and, not just because of different owners demands and expectations but also the seasonality and operational profile.

Many yachts, apart from shipyard periods, operate all year round, on standby for visits at the drop of a hat. These tend to be larger yachts and so full manning required can more easily be justified.

Smaller, or one season yachts, are a more complex situation. Whilst it might be essential to have 19 crew during the season, it may be difficult to justify that number sitting in port for the winter with no guest movements where a more appropriate number might be 12 i.e. sufficient to safely man and maintain the yacht in good order. And, if that choice was made, at least you have the berths necessary to increase crew for the season; though it should be noted it is easy to downsize a crew but, much more difficult to upscale again and expect the same quality of crew, personalisation, level of service, operation and safety standards.

Importantly, manning levels should be determined by the peak periods of operation; after all, that is when an owner or charter guest gets to experience the depth and quality of service.

### Superyachts Today

In my time I have seen the whole industry evolve and so many positive changes have taken place.

Today, yachts are better built, more reliable, safer, officers and crew better qualified and trained, employment conditions improved, and there is now much better support available from yacht management and other shore-based service providers. At the same time, there has also been an incremental increase in owners expectations – some examples below: –

• Yachts and guests now rely heavily on electrical/electronic and AV/IT systems
• Beach clubs’ add another deck to be servced
• SPA therapists, hairdressers, gym instructors, nurses, nannies, are now routinely carried – are they single or dual role? Whatever the case, it generally means service and housekeeping are stretched as they lose a member to other activities
• Every night is ‘theme night’ with new table decorations and service expectations
• Photograph/video guest experience and provide a personal record for guests to go home with
• Flight crew, security and owners staff can add to numbers carried and place their own demands on crew
• Tenders are bigger, requiring more crew to launch and operate
• More toys carried like inflatable slides -heavy and labour intensive to setup/breakdown, especially when wet! – an ever-expanding list of toys, diving equipment, motorcycles, etc. – all require crew and maintenance
• Diving, Pilates, jetski, sailing, windsurf, kite surf…an almost endless list of activities
• Accommodation for river or ice pilots for yachts traveling further afield

These are further compounded by an increase in paperwork that is a fact of modern yachting e.g. budgets, purchase and approvals, crew HR functions, maintenance and refit planning, safety management systems, and management reporting – this generally falls on the shoulders of the captain and senior crew. One study on a 100m+ showed that the captain was spending 33% his time on their management companies demands which, along with their normal duties and responsibilities, was clearly unsustainable.

Whilst there has been some positive changes in the industry that should be celebrated, the evidence suggests that manning levels maybe one element that has not profited from the evolutionary process.

Perhaps yacht crew are partly to blame for this due to yachting culture, as already posited, where they will work all hours necessary to deliver the very best experience for owners and guests, and often do so without complaint or communicating the problem outside of the yachts team. And, apart from this cultural norm, there are also undeniable concerns about job security where captains and crew may be reluctant to speak-up and/or report their hours of work and rest accurately for fear of losing their job. However, it is important as proper reporting helps to educate owners and the wider industry. Furthermore, if there was an incident and an inquiry, if falsification of hours of work were discovered and fatigue the root cause or contributing factor, it could have serious consequences for the crew, especially the captain.

### Conclusion

The quality of captain, officers and crew and, the onboard experience is, without doubt, key to the success of a superyacht and this can only be achieved with the right manning levels which, unfortunately, have not kept pace with the advances made in the rest of the industry.

As the ISS piece stated ‘for the love of yachting’ we need to have an honest conversation about manning that includes owners and all industry stakeholders, especially those with operational experience. Getting this right improves the health and well-being of the crew, their performance, retention, yacht safety and, ultimately, leads to a better ownership experience.
