Superyacht Coatings ONBOARD Magazine

MODERN TECHNOLOGY AND ENVIRONMENTAL ISSUES ARE LEADING THE DEVELOPMENT OF PAINTS AND COATINGS FOR THE MODERN SUPERYACHT INDUSTRY

The way the superyacht industry meets and merges with the paints and coatings market has come a long way in the last 20 years. Back in the first months of this century it was not uncommon to see the clause; ‘The vessel shall have a Super Yacht Finish’ as being the only specification when it came to exterior coatings. Yet despite yachts of that time being well respected for their quality in finishing the fact was that paint technology did not play as a significant role then as it does now.

Quality Assurance Control Consultant Nico Roper of Atlas Paint Consultants believes that in that period, larger vessels were produced, paint and fairing system application times shortened and products adjusted to comply with ever changing environmental requirements. He says, “This all has had its effect on the paint applications and the need for properly described Application Guidelines, Specifications and Quality Assurance / Quality Control requirements.” He adds, “Today new build and refit paint projects start with set up and production of tailor made Specifications and Inspection Testing Plans, which clearly describe the requirements for each main step in a paint and or fairing application process and how this shall be verified and documented.”

Documents such as these specifying paint standards are constantly being developed and improved. The industry today has access to these professional tools and they provide process control helping all parties involved to achieve the agreed technical and cosmetic result on all painted areas of a superyacht.

It is not just in the world of superyachts that practice is embracing modern expertise. The technology behind the automotive paint supplied to a F1 team gives a significant drop in weight. But the demands placed on above-the-waterline marine coatings are somewhat different to the demands required of a coating on a Formula One race car. Inge De Jonge, Product and Marketing Manager Imron Marine for Axalta in Europe, the Middle East and Africa says, In Formula One, a coating’s speed and weight are key - the speed of the refinish process because of the vast number of components and the tight timeframe, and weight of the coating can not have a detrimental impact on the overall weight of the car. She adds “Marine coatings on the other hand are exposed to extreme weather conditions, in particular the ravages of saltwater, so durability is key. This is compounded by the fact it is not an easy task to dry dock and to refit a yacht, so marine coatings must be built to last longer, with the speed and weight of the paint being of secondary importance.” As a global company Axalta is focused solely on coatings and providing customers with innovative, colourful, beautiful and sustainable solutions. From light OEM vehicles, commercial vehicles and refinish applications to electric motors, buildings and pipelines, their coatings are designed to prevent corrosion, increase productivity and enable the materials they coat to last longer.

Malcolm Kerr one of the owners at Storm a paint specialist company working across the world with new builds and refits thinks the question needs to be more specific. He says, “First thing we need to clarify is what is meant by UV protection, because when we mention UV protection this could be referring to the durability of a coating meaning gloss and or colour retention and that has nothing to do with heat absorption.” Kerr adds, “In terms of durability there is no huge difference between whites, blues, etc – only colours like reds or oranges have poorer gloss or colour retention thus less UV resistance. In terms of heat absorption
– it’s known that darker colours absorb more radiation/heat, meaning light colours like white are better to keep vessels cooler.”

It is an established fact that one leading paint manufacturer limits the absorption of heat and thus makes the use of darker colours more feasible. Kerr says, “These coatings incorporate specialist pigments into the finish paint formulation which are designed to reflect sunlight and thus absorb less heat, keeping areas cooler and at a more constant temperature. Here at Storm we have had positive experiences with these products in the past and would happily use them again.”

THE WHITE STUFF
Superyachts are increasingly veering away from the traditional white hull as colours become more reliably stable. The 72 metre Axioma is sporting a fresh new blue coloured hull in recent months and is a prime example of that trend. The fact remains however that, white is the most popular colour due to UV and heat protection.

We asked Christopher Rothe at Wrede if the same UV protection and heat deflection could be applied in equal measure to coloured coatings. He responded saying, “Not currently, research is ongoing into creating coatings that appear visibly dark yet also reflect UV radiation. Such products will be a huge boost to the entire coatings sector and not just superyacht coatings.”

At Axalta, Inge De Jonge believes, “It is possible to achieve the same UV protection in coloured coatings as it is for white coatings when a clear over base system is used. In this scenario the UV protection comes from the clear coat. When it comes to heat deflection, however, white will always perform slightly better as heat from solar absorption is linked with the absorption properties of the pigments.”

Better products are the result of research and development and there is evidence that the investment into that field is beginning to pay off. Awlgrip are for example now officially trialling a fully sprayed filler system. Axalta, a global market leader in colour technology. “At our R&D facilities around the world,” says Inge De Jonge, “We are continuously investing to develop new and better performing products that not only meet but also exceed our clients’ needs, while also maintaining a strong focus on our environmental impact. We have a number of developments in the pipeline that are being designed with those key values in mind.

Malcolm Kerr at Storm highlights the move towards electrostatic painting as another major step forward. He says, “This still needs a lot of work and expectations on the resultant ‘finish’ need to be managed as they are different to the standard ‘conventional’ finish. In our experience, environmental control and replication of atmospheric conditions is fundamental with electrostatic painting.”

Kerr adds, “We are currently working on two innovative projects ourselves when it comes to R&D. One being a custom app for management and quality control, thanks to a successful European funding grant. The second being an environmental control system which can also monitor emissions ¬the objective being to subsequently reduce emissions.”

Like both the aviation and motor industries, weight is a factor and in this regard R&D in this field is important. Christopher Rothe says, “On some high speed light weight projects it can be very important. If we can fair and paint yachts using fewer and lighter products, then this has considerable benefits both environmentally and in terms of reduced running costs.” Generally the fillers used by Storm are lightweight so the weight of the filler is negligible considering the other products on a yacht,” says Malcolm Kerr. “A pallet of filler could weigh less than a marble worktop so I would say that weight isn’t particularly an issue in regard to coatings.” Ewan Clark from Aquarius Marine Coatings says, “It is easy to be side-tracked with the notion of ‘weight’. Of greater importance is the efficacy of the anti-foul itself and the amount of drag it creates.” Conventional anti-foul paints absorb water when launched, so swell, increase in weight and roughen at the surface, which causes an increase in drag (leading to reduced fuel efficiency and hull performance). Coppercoat-Superyacht, on the other hand, is a non-absorbent epoxy resin. When launched it does not swell, increase in weight or roughen, and instead provides a smooth and lasting resinous surface, ideal for maintaining both boat speed and efficiency.

VOLATILE ORGANIC COMPOUNDS (VOCS)
Because of ever stringent environmental regulations and concerns, for those manufacturing paint products the reduction of VOCs carbon-based chemicals which evaporate easily at room temperature is an absolute priority. But as Christopher Rothe at Wrede points out these are less of a priority for the yachts and owners who are primarily concerned with the appearance and longevity.

The reduction of VOCs in our products is a huge priority for Axalta says Inge De Jonge. “However, reducing VOCs while still maintaining the outstanding performance of coatings is a challenge, and this is particularly true of marine coatings, which are exposed to extreme conditions. This is why we continue to invest in our research and development of lower VOC coatings that still offer a virtually unlimited choice of brilliant colours and that last a lifetime.”

Malcolm Kerr at Storm, points out, “We live in a world that is no longer willing to accept pollution to the levels we have been producing in recent times. We believe that the coatings’ manufacturers have a massive role to play here in developing greener products … and the industry as a whole needs to perhaps accept the subsequent ‘finish’.”

Ewan Clark at Aquarius Marine Coatings who make Coppercoat the anti fouling bottom paint used by a great many superyachts believes, “The reduction of VOCs in coatings is vital. Indeed, all our anti-fouls are completely VOC-free, and this was a key part of their original development. So while we have fully ticked the VOC-free box, many other coatings manufacturers have room for improvement!” Coppercoat-Superyacht provides very long lasting protection against bio-fouling, with a treatment typically remaining effective for at least 10 years. This saves the time, expense and logistical problems associated with repeated applications of conventional anti-foul paints. It is also a more environmentally sound choice, being both VOC-free and water-based, with no end-of-life problems. And it does all this while providing a smooth, low-drag surface that allows the vessel to sail quickly and efficiently.

IT’S ALL IN THE DETAIL
Yacht detailing products and yacht cleaning supplies from the US based Sea-Shield have been developed over the years by experienced professionals working within the superyacht industry. Their Francisco Linares understands better than most, the task involved in yacht detailing and the importance of adding a protective barrier against the damaging effects of the sun and the sea. He says, “We developed products to make the crew’s life easier. When our products are applied, maintenance time is substantially reduced. Future wash downs get easier every time Sea Shield is used and so ensures the yacht has the best protection available.”

The application of ceramic protective coatings will seal the pores on paint, glass and stainless, preventing them from being damaged and creating an uneven surface that will never shine no matter how many wash downs are done. From the crew’s point of view, washing down a surface sealed with a smooth ceramic coating is quick and easy and results in the perfect shine. These specialist polymer and ceramic coatings enhance and protect the exterior paint surfaces against ultra violet, salt, dirt, exhaust fumes, oil and a host of other contaminates. Using a good polish can delay a paint cycle and if applied from new or whilst still in good condition can extend the life of the paint for years.

WORKING CONDITIONS AND PLANNING
Malcolm Kerr of Storm believes that when it comes to working conditions, planning and management the key word is ‘consistency’. We work in a world of custom yachts in a job that has no real recognised schooling or training. This is a massive challenge. The more we can create a uniform work process, the better the chance we have of consistent and acceptable results.
Ewan Clark, Aquarius Marine Coatings says, “For our Coppercoat antifoul to adhere for the long term, and provide its standard 10 years of protection, the substrate must be clean, dry, stable and matt. As Coppercoat-Superyacht anti-foul is a modern water-based epoxy resin, it must be applied in dry, mild conditions. If a vessel is to be treated in the open (as opposed to in a shed or covered dock), a tent or kirt should be attached to the topsides to protect the below water-line sections from any precipitation. When it comes to job planning, the most important elements during application, are atmospheric, clean air, and temperature control.”

Wrede Consulting GmbH, with its headquarters in Hamburg and locations in Bremen, Barcelona, La Ciotat, Rotterdam and Palma de Mallorca, provides independent consulting for coatings from new builds to refits with specialisation in superyachts. Founded in 1999, the company owes its success to the many years of experience of its independent paint consultants and surveyors, as well as to state-of-the-art, innovative technology. Speaking on behalf of the company Christopher Rothe says, “For the finest results, conditions have to be provided so that the applicators have no excuses for not delivering an excellent result. This means, time, space, lighting, cleanliness, stable environmental conditions, planning, scheduling.” At Storm, Malcolm Kerr says, “It is vital to replicate, as much as possible, the ambient conditions. Reducing the variables is key to a successful paint job.”

When painting, it is always best to avoid extreme air quality or temperature conditions. Low temperatures will for example increase drying times while high temperatures will reduce drying times and can make application more difficult, as product flow and levelling is compromised. Optimal painting conditions are when the ambient temperature is between 10 - 26° Centigrade and relative humidity is below 65%.

It is always best to avoid painting in direct sunlight, or when the substrate itself is excessively warm. One good way to check this is to check the surface temperature using a specialised surface thermometer.
With over 20 years experience crewing superyachts, Duncan Sykes the Managing Director at Absolute Boat Care, understands absolutely the requirements and demands of captains and owners alike. Based in Mallorca, they have a large, highly professional team who have the capabilities to undertake absolutely any job, whatever the size. Captain Jason Lambourne, of the motor yacht Angara has enjoyed working with Absolute Boat Care and done so for the past four years. He says, “The products and the knowledge they employ when polishing Angara have always given her an incredible shine and made sure she is looking fantastic for her owners every season.”

WARRANTIES
Captains like Jason Lambourne want more than just a good looking yacht. They want her to stay looking good and they look for answers if that is not the case. That’s where warranties come into play. Christopher Rothe says, “The variables in which a yacht is used and maintained once a project is completed mean that is it impossible to truly warranty the result beyond what might be considered a major failure. These are rare, but lesser issues remain a constant discussion point.”

“Warranties need to be adequately managed,” says Malcolm Kerr of Storm. The point being that in order to manage warranty, you first need a definitive list of what is covered / not covered. Fundamental is a detailed mapping of all problematic areas (e.g. corrosion points on refit) found during the complete work process.”

“It is important to manage client expectations. We do this,” says Christopher Rothe, “by demonstrating the achievable and being fair and consistent in one’s appraisal of results and communication with the client.”
“Transparency is the key,” says Malcolm Kerr. “It’s very simple, starting with a kick off meeting is imperative and constant detailed reporting and dialogue is an absolute necessity. No secrets, no short cuts, everyone stays on the same page.” Coppercoat concur that clear lines of communication are paramount. Ewan Clark says, “By listening carefully to the requirements of the client we will provide them with an accurate and honest report of what they should expect from our products.”

CONSULTANCY
Whatever the size of the project there are benefits of employing a yacht consultancy. Christopher Rothe at Wrede says, “Yacht crew and management generally do not see very many paint projects and are not suitably qualified to make some of the decisions that maybe asked of them. A good coatings consultant will provide expert advice and insight into a project to help it progress effectively to completion and also relieve some of the pressure from the crew and management.

Malcolm Kerr at Storm says, “Our experience of yacht consultancy is limited to the coatings aspect. We regularly have coatings surveyors checking and controlling our works. There can be a tangible benefit if said surveyor is qualified and has the same objectives as the rest of the project i.e. getting the job done to an acceptable standard in the given timeframe. Unfortunately, the truth and reality of the matter is that some surveyors are only in the game to invoice and create as many site visits as possible, whilst having very little responsibility.” Back at Aquarius Marine Coatings, Ewan Clark says, “When relevant, we like to personally oversee applications, alongside any existing surveyors, managers and consultants. By being on-site we can immediately react to any situation and thereby ensure the smooth running of the project.”
Smooth running projects and a smooth finish are clearly the end results for those who, in the industry, are painting a better future for the superyacht coatings fraternity.

ABSOLUTE BOAT CARE

FRANCES AND MICHAEL HOWORTH LOOK AT THE LATEST PAINT AND ANTI-FOULING COATINGS ALONG WITH VINYL WRAPPINGS IN USE THROUGHOUT THE SUPERYACHT INDUSTRY TODAY

Call it the big cover up or even, if you want to; a protection racket but the fact is: we are not entering the realms of writing about crime fiction. We are talking here about protective coatings as applied to superyachts.

With the constant need to keep a superyacht looking good, the informed maintenance and application of protective coatings is becoming an increasingly important task for the accomplished member of crew. Today’s crew person needs to

know how everyday issues relating to paint and varnish can be coped with and with manufacturers each claiming that their product can either cut emissions, boost performance or improve fuel economy, there is a lot more to the protection racket than just a chamois and squeezy blade.

Yachts live in some of the most corrosive conditions for paintwork in the world attacked constantly by high doses of ultra violet light and salt water. Paint surfaces are porous with millions of microscopic holes. Salt crystals get into these holes and act a little like the tip of a screwdriver boring away making the pores bigger. The sooner these salt crystals are removed the less damage is done. The less damage is done the smoother the surface and the smoother the surface the shinier the boat looks, as light is refracted in a focussed single beam rather than diffused in many directions.

Yacht detailing products and yacht cleaning supplies from the US based Sea-Shield have been developed over the years by experienced professionals working within the superyacht industry. Their Francisco Linares understands better than most, the task involved in yacht detailing and the importance of adding a protective barrier against the damaging effects of the sun and the sea.

Using a good polish can delay a paint cycle and if applied from new or whilst still in good condition can extend the life of the paint for years.

CERASHIELD
CERASHIELD

When discussing this with Andy Williams from CeraShield he explains “All our coatings have been especially formulated and engineered. With the harsh environments that superyachts find themselves operating in its essential to protect against harmful and damaging UV rays, soot and exhaust emissions, acid rain oxidation and salt deposits. Our next generation, premium Ceramic and Sio2 coatings can also restore and seal faded paint and gel coats. Once applied the ceramic coating forms a gas barrier which means no soot or exhaust emissions can penetrate the coating and leaves the surface with a slick, glass like finish that is very easy to clean and maintain without the use of aggressive chemicals and leaves the crew free to perform other important duties around the vessel.”

Isofan and Stoppani are paints made for the yachting market by the German Lechler Brand. Since 1883 Stoppani has dedicated special care to product quality and reliability. The product range they offer is continuously evolving using Lechler’s technological expertise with the aim of offering innovative paint processes to fully satisfy the different yachting segments’ needs. The Isofan Marine product range includes solid, metallic and pearl finishes of matchless gloss, light fastness and ageing resistance for yachts, pleasure and sailing boats.

The difference between a good paint job and poor one is always said to be down to the preparation. It is a cliché, but it is also true, that 99% of every good paint job lies in the preparation. It doesn’t matter if the finish is wood or fibreglass, the prep work still has to be done. This begins with removing all hardware, railings and decorative strips. Except where the complete removal of the object cannot be safely achieved the use of masking tape should be avoided. Before applying any coating, check that air conditioning units that vent on the area to be coated are cleaned or if possible that the fans have been turned off. It is a sad fact of life that the Sahara Desert is just too close to the marinas on the northern shores of the Mediterranean. That and the fact that superyacht docks are often close to roads, means that whenever crew are trying to paint a surface outside they encounter dust. Minute particles of sand or road grit are generally invisible to the eye but add a layer of wet coating to a surface and the annoying molecules of grit can quickly spoil hours of hard work. It’s a really good idea to use an air compressor to blow away dust from its surface and then to sprinkle clean fresh water on the deck, in the area being coated. This will help keep dust on the deck and help prevent it moving around in the air.

Kevin Viles recently sold out his fairing and painting company Concept Yachts Finishing brand to Finishing De Luxe in Germany and joined the board of the newly enlarged company as Commercial Director. Now with offices in the UK, Holland and Germany the company currently has five projects over 50 metres running simultaneously inside Heesen Yachts, along with two 90 metre refit projects underway at Royal Huisman.” Director Chasan Kalfoglou says, “For us it goes without saying that good preparation is one of the most important steps that we take on our projects. A high standard of preparation starts from day one and we maintain a high standard throughout the process.

These steps in preparation are crucial for the final result as poor preparation is easily spotted in the final top coat (gloss) and could easily compromise both manufacturers warranties and the overall finish of the vessel. The client expects a very high quality finish and as a standard we strive to provide this every time. Taking steps backwards on a project due to poor preparation is never efficient and extremely costly, so why risk it?”

Longevity, high gloss and easy cleaning are the standout features offered by a new class of coating made possible by recent advances in ceramic chemistry: Zytexx Clear-Coat. When using this revolutionary ceramic coating, salts, pollutants, acid rain streaks, oils and diesel soot are all easily removed. The hard, slick, abrasion-resistant finish does not wear down like waxes, polishes and polymers.

More importantly the product cuts crew cleaning time down to a fraction. By preventing diesel soot from permanently staining polyurethane paints, crew can avoid unsightly and expensive damage and eliminate the need to tediously polish out these defects. With its hard, scratch-resistant properties, fenders and hawsers mark Zytexx far less than paint. The company has supplied over 90 vessels in the Mediterranean alone all are using it to great effect. Captain Eddie West, in command of Sarafsa, is a big fan and has stated, “Zytexx has without doubt, extended the life of our paintwork to the extent where we have original paint of 11 years old in some areas. Glass readings were as low as 7 prior to using Zytexx and now readings are in the high 80s on this old paint. The application team are quick and efficient, just give them a cherry picker and leave them to it.”

Speaking for the company, Michael Pass says Captains should look out for Zytexx for glass surfaces. He says, “Our Glass Treatment restores salt pitted windows to clarity, greatly enhancing the look of your vessel. Treated windows become extremely water repellent; Water literally rolls right off eliminating spotting and reducing further etching. Even on windows fitted with wiper blades, Zytexx Glass Treatment provides long-lasting hydrophobicity.”

Nico Roper of Atlas Paint Consultants believes it is important before contemplating any large scale painting project, specialist firms such as his are called in. The job of a consultant should be to carry out a full pre refit paint status survey. Once that is done the consultant should prepare a bid book to reflect all the necessary requirements. Then he should have the yard and or the paint contractor prepare a paint manual. “It is vital,” he says, “to list the responsibilities and communication lines to make sure there are clear and open corporation between all parties”.

Painted surfaces that have a dappled look about them are often referred to as having an orange peel finish because of the texture of the surface after coating resembles the skin of an orange or grapefruit. This phenomenon is almost certainly the result of improper painting a technique, and can often be caused by fast evaporation of thinners or when using an incorrectly set up spray gun. It can also arise when a surface is painted with a roller using too little pain or too thick a paint so that the surface dries before the texture as a whole does so. When using a spray gun check the air pressure and ensure the correctly sized nozzle is fitted. Avoid spraying paint at an angle other than perpendicular to the surface and never apply an over excessive amount of paint.

He says, “The products and the knowledge they employ when polishing Angara have always given her an incredible shine and made sure she is looking fantastic for her owners every season.”

When applying epoxies in high humidity conditions they can develop an ‘amine blush’ on the surface particularly at lower temperatures. This slightly sticky substance must be removed and can normally be washed off with soap and water. If the blush is not removed it can lead to the delamination of subsequent coats. High humidity conditions can reduce the amount of solvent evaporation during the drying/curing stages; with epoxies this can lead to a ‘soft cure’ where solvent can remain trapped in the film for many days leading to slow or poor final cure.

Patching paint is always tricky. There are some who say patching should always be thought of as a temporary repair because it will more than likely always be identified as such. Others believe that done well it is hard to tell if a patch repair has been made or not. It is a truism, however, that hard cut lines are almost always visible, especially in darker colours the likes of dark blues and blacks. They should, be avoided in areas where they are going to be very easy to spot.

It is of course imperative to use the same brand and colour as the original when trying to perfect the repair. One good tip is to keep a log of what is painted when it was completed and what product was used noting any batch numbers or identification codes shown on the tin. That way you know exactly what colour was originally used.

Some experts suggest it is best not to polish hard cut lines advising, hard cut lines will look worse than if they were simply left as they were. It is sometimes better to paint an entire section than a patch in the middle of a surface, as you would have less risk of it being visible. Larger areas are often better than smaller ones. Polishing out soft cut lines using specialist polishes is always the better solution. Certain paints can be polished and others cannot be polished, so be aware of what is possible before you start. A well polished patch when done properly will be almost invisible.

Versatility
One certain benefit of Ceramic and Sio2 coatings from CerShield is the ease of cleaning. “All that’s needed by the crew is a simple pH neutral soapy washdown” says Andy Williams. “No aggressive chemicals or polishing is required, which considerably cuts down the time crew members are kept away from other important tasks and is obviously better for the overall health and safety of the crew and means that no harsh chemicals are being dispersed into our oceans”

Williams continues, “But it’s not just the paint work that can benefit, why not apply to metals and glass? Metals onboard would no longer need to be polished before every boss or guest trip. The coating keeps the metal looking bright with that ‘just polished look’. Plus glass, which quickly becomes oxidised and suffers from calcium build up can be protected. Once the coating is applied the surface becomes hydrophobic and repels the harsh environments for a much longer period of time. And, for the longer term we have devised a 5 year gloss protection programme. For its duration, and longer if required, we send CeraShield teams to wherever the vessel is having downtime for maintenance, to undertake an agreed portion of the 5 year protection plan. This will then guarantee the vessels exterior painted surfaces will always remain glossy, simple!”

Based in Palma de Mallorca, Pure, headed up by Nic Clarke has painted over 20 superyachts in the 10 years the company has been in business project managing refits. He says, “I know a bit about paint and coatings but could not be regarded as an expert. That is why we always retain the services of a paint surveyor, sometimes much to the annoyance of the applicators working on the project. It was the project management style of the company that secured the responsibility of completely repainting the exterior of the 70 metre Lurssen built Saint Nicholas and it was perhaps because of the paint quality that this yacht exchanged hands so quickly one released onto the brokerage market.

Bottom coats
Aquarius Marine Coatings Ltd. manufactures the high-performance multi-season antifouls Coppercoat, Coppercoat-Superyacht and Coppercoat Commercial. Since launching in 1991, these coatings have proven to be durable and long-lasting. These hard-wearing and densely copper-filled epoxy resins provide protection against unwanted marine growth for many years (commonly over a decade). To date, more than 60,000 sail and power vessels have been treated with Coppercoat in the leisure, commercial and superyacht sectors.

Coppercoat consists of copper powder and resin, and its non-ablative characteristics mean it will firmly adhere to a wide variety of surfaces including GRP, concrete, steel, iron and aluminium. Its leach rate is less than 50mcg/cu/cm2 after 30 days. Managing Director at Coppercoat Ewan Clark says, “Increasingly restrictive laws governing the use of biocides in ant-fouls weighs heavily on coating manufacturers. Within Europe, the latest Biocides and Pesticides Register has reduced the number of allowable biocides by approximately 80%. The armoury available to paint chemists has been severely depleted.” He adds, “But a restricted choice of ingredients and a lowering of biocide levels need not result in poor performance. The latest coatings technology concentrates on making best use of the ingredients. The latest Coppercoat-Superyacht anti-foul being a case in point. The water-based, VOC-free epoxy carrier is loaded with pure copper particles, curing to create a semi-permanent outer surface so copper-rich as to be inhospitable to virtually all bio-fouling.”

The proof of the pudding is they say is in the eating. Coppercoat is currently celebrating its own memorable proof in the aftermath of the 2017-2018 Clipper Round The World Race. When the Clipper boats were finally lifted out after 40,000NM of racing and 16 months of continual immersion, the Coppercoat on their hulls revealed almost no loss of coating thickness. Barring the faintest trace of slime at the waterline in some parts, the hulls were virtually spotless.

So well did the Coppercoat antifoul perform that, for the first time in the Clipper’s 22-year history, the boats did not need to be lifted out at the race’s halfway mark in Sydney. As every boat owner is all too painfully aware, lifting out vessels to clean off old antifoul and apply a new coat can be a slow and costly business, so Coppercoat’s matchless resilience meant substantial savings in time and money for Clipper Race organisers and crews alike. “This enormously successful outcome understandably delighted us, the crews and the race organisers in equal measure,” adds Ewan Clark. “Look no further for a clear vindication of Coppercoat’s efficiency and longevity.”

Such positive feedback contrasts markedly with recent testimony from sailors involved in other global circumnavigations, who reported that rival coatings used on their boat hulls only lasted for less than six months. Even, by this point, barnacle growth on hulls was so advanced that it was calculated to be responsible for a 0.5 to 1 knot reduction in boat speed for every hour sailed.

It’s a wrap
Paints and varnishes are not the only way to protect surfaces and keep things smart. Vinyl wrapping is a way of protecting a paint finish with a plastic layer, rather than a chemical topcoat. The process known as wrapping has developed dramatically over the past decade and has moved into the premier league of coatings and is no longer simply in the realm of those seeking to temporarily advertise a new product or design on the side of a commercial white van. Vinyl allows for special effects the likes of pearlescent or matt effect to be applied if required, and we are now seeing many interiors receiving a fresh coat of vinyl...

We have the ability to give our clients choice for the method of their anti-foul system application due to the fact that we have such an experienced team. 70% of our clients opt for an airless spray application to ensure an even coverage and better performance due to more paint being applied during the process. The ability to use a spray application means we can achieve a smoother finish giving the added benefit of saving fuel as it allows the boat to travel easier through the water.

Over the years, we have built a fantastic relationship with our Akzo Nobel technical representative to ensure the perfect result, and out of the 350 applications, approximately 35 projects were sandblasted back to bare metal, or primers, and a full new anti foul system applied. We are also authorised Propspeed and Propgold applicators and use one or the other to approximately 80% of jobs.

We are proud of our dedicated team for all their hard work, and achieving this milestone of 350 anti-foul applications. It just goes to show that for the best and most experienced team, our clients keep coming back to Absolute. We look forward to the next 350.

Absolute Boat Care have a number of long standing clients that return for their anti-foul and other finishing services year on year. The First Officer of M/Y Vava comments on the service they have received over the years.

We have been using ABC for our anti-fouling for the last three years and during that time we have always found their service to be of the highest quality as well as being very competitively priced. I have no hesitation in recommending them.
