Arkea Ultim Challenge Skippers Ready to Go

• By OC Sport Pen Duick
• January 2, 2024

Compared with previous generations of round the world racers and adventurers, the six skippers ready to take on the Arkéa Ultim Challenge – Brest on January 7 are a new, different breed. Physically most are fitter and stronger than those who preceded them. Bear in mind each manoeuver is usually nearly 45 minutes of hard, physical work, not least requiring long periods at max effort on the pedestal winch.  


The “coffee grinder” is what Armel Le Cléac’h (Maxi Banque Populaire XI) calls “the hand bike.” The heart rate climbs, the arms, shoulders, chest and lower back are fully engaged and the beads of sweat very quickly become rivers of perspiration.

“I keep up a level of exercise so that we prepare all throughout the year, to just be able to maintain that level of sustained power output endurance and a good recovery,” says Le Cléac’h, skipper of Banque Populaire.

“It’s not really about all out power, max work rate like on an inshore grand prix boat, but it requires really excellent cardio, and core strength too.” He says

“In fact, it’s more like a trail run rather than a sprint,” adds Charles Caudrelier (Edmond de Rothschild). He ensures he does at least three physical preparation sessions per week and among them enjoys boxing, climbing, board sports, running and cycling. And in his build up Armel Le Cléac’h says he has worked out almost every day with swimming sessions, time in the weights gym or out on the bike.

Anthony Marchand (Actual Ultim 3) is mainly happy to just ensure he does a lot of water sports, regularly going kiting, winging, and surfing. “These allow you to work your cardio,” he says. “All your muscles and I like that it’s always in the same watery environment!”

At the same time everyone has also really focused on working on mental strength.

“If we have to deal well with the many different types of physical challenge that this race will bring, the mental dimension is almost more important,” says Tom Laperche (SVR-Lazartigue). “We just can’t overlook the mental demands of these boats and the impact that this stress can have over time.”

“The mental aspect is undoubtedly actually more valuable than the physical tests on this race,” agrees Charles Caudrelier.

“It’s not a race, it’s an expedition,” says Thomas Coville, skipper of Sodebo Ultim 3. Coville is the skipper who has completed the most round-the-world passages on a multihull—competing in five, completed the loop three times and was once the record holder around the world (49 days and 3 hours in 2016).

“We need to find the right approach to sustain the right level on this unique and singular challenge,” he says. “There is a very big psychological dimension. We are constantly seeking to work at or near our limits, to go beyond normal effort levels despite the accumulated lack of sleep, the risk, the frustrations, the anxiety, the ice.”

For Coville, the Arkea Ultim Challenge goes far beyond the scope of a sporting competition. “I like to tell myself that we are not racing but that we are on a tough expedition. There are days when you burst into tears, days when you scream, days when you go crazy. You end up being a mix between euphoria, exhaustion and elation.”

“What I’m looking for is a good level of balance” says Le Cléac’h. Yet all the skippers have their methods. Charles Caudrelier and Tom Laperche work with mental coaches. Caudrelier, the Edmond de Rothschild skipper, says, “with my physical trainer, I am very Cartesian, very numbers driven. We talk about fatigue, recovery, nutrition. And, of course, there are the times when you are exhausted without realizing that you are in the red zone.”

Laperche adds: “We know that there will be moments of euphoria, moments that are really challenging on the morale, so we work out how to manage this and to smooth out these emotions as much as possible to create the best possible performance.”

There are also those who do not have a mental trainer. This is the case with Anthony Marchand and Armel Le Cléac’h. Marchand says, “If you’re doing your second round the world you’ve seen the problems, you know what to focus on. Me, I’m a rookie: I go in ready to fight and obviously I ask myself fewer questions.” And blessed with so much experience, Armel Le Cléac’h prefers to focus on preparation. He wants to enjoy a level of confidence because he has mastered everything that makes up the pre-race preparations. “I try to tick all the boxes before the start,” he admits. “Above all what I am looking for is a balance in physical and technical preparations, in terms of recovery as well.”

Arkema 4 has drawn on the experience of Arkema 1: naval architect Romaric Neyhousser has designed a more versatile trimaran, capable of performing not only in solo ocean racing but also round the cans during the Grand Prix, an important part of a Multi50 season. The care that’s been taken to limit aerodynamic drag (integration of deck fittings, fairings and aero covers) is plain to see. But the most innovative part lies in the large cockpit. Flanked aft of the X-shaped arms, it allows the crew to maneuver the sails while fully protected, and ta the same time helping to lower the center of gravity. Removable for the Grand Prix races, the coachroof offers remarkable protection for single-handed sailing. Coated with a scratch-resistant and water-repellent varnish, its multiple panes of glass are made of PMMA, which is ultra-light and particularly resistant to impact. Also noteworthy are the structural adhesives used to assemble the structure, and the latest generation lithium batteries. Although the official skipper of Arkema 4 is the young Quentin Vlamynck, his mentor Lalou Roucayrol will be at his side for the coming seasons, as a way of passing on knowledge!

Breaking Records in Transat Jacques Vabre

Published on November 16th, 2017 by Assoc Editor -->

(November 16, 2017; Day 12) – There was joy unconfined in a glorious sunrise in the Bay of All Saints as the Franco-Spanish duo of Lalou Roucayrol and Alex Pella crossed the line on their foiling 50ft trimaran, Arkema to win the Transat Jacques Vabre Multi50 class.

Lalou Roucayrol (France) and Alex Pella (Spain) on their 50ft trimaran, Arkema have won the Multi50 class of the 13th edition of the Transat Jacques Vabre after crossing the finish line in the Bay of All Saints in Salvador de Bahia on Thursday, November 16, 2017 at 07:49:19 (UTC), 10 days 19 hours 14 minutes and 19 seconds after leaving Le Havre, Normandy France.

Arkema covered the theoretical course of 4,350 nautical miles at an average speed of 16.81 knots, but actually sailed 4,671 nautical miles at an average speed of 18.02 knots.

Arkema beat the previous record of 15 days 22 hours 27 mins and 37 seconds set by Franck-Yves Escoffier and Karine Fauconnier on Crêpes Whaou! in 2007 (the last time the race finished in Salvador de Bahia) by 5 days 3 hours 31 minutes and 18 seconds.

Arkema’s win struck another blow for the underdog in this Transat Jacques Vabre as they beat the favourites in to Salvador de Bahia. Something that favourites Jean-Pierre Dick and Yann Eliès on St Michel – Virbac seem certain to make sure does not happen in the Imoca class. But Phil Sharp and Pablo Santurde are doing their best to cause another mini-upset against the two powerful French teams toiling alongside them in the Doldrums.

But the south-east trade winds brought the most mixed news to the 13th edition of the Route de Café over the last 24 hours. Thursday woke to the 80ft trimaran Prince de Bretagne being towed back to Salvador de Bahia after dismasting yesterday evening just 93 miles from the finish line.

Multi50: Arkema breaks race and 24 hour speed record It was ninth-time lucky for the 53-year-old Lalou Roucayrol. When his co-skipper, Karine Fauconnier, was injured in training three months ago, Roucayrol was looking for the best to help win his first Route du Café. In Alex Pella, the formidable and multi-skilled, multi-starred Spanish sailor, making his third appearance, he found both that and hunger. Both had finished second in the race before – Pella in the Class40 with fellow Catalan, Pablo Santurde, in 2013 (who is currently leading that class).

Interview with the winners

They sealed their win with a masterful comeback in the Doldrums taking 160 miles in 42 hours off FenêtréA-Mix Buffet, skippered by the “dream team” of Erwan Le Roux and Vincent Riou, who have five Transat Jacques Vabre victories between them.

Arkema won the Multi50 class of the 13th edition of the Transat Jacques Vabre after crossing the finish line in the Bay of All Saints in Salvador de Bahia on Thursday, November 16, 2017 at 07:49:19 (UTC), 10 days 19 hours 14 minutes and 19 seconds after leaving Le Havre, Normandy France. Arkema covered the theoretical course of 4,350 nautical miles at an average speed of 16.81 knots, but actually sailed 4,671 nautical miles at an average speed of 18.02 knots.

Arkema beat the previous record of 12 days 06 hours 13 mins set by Franck-Yves Escoffier and his son, Kevin Escoffier on Crêpes Whaou! in 2005 by 1 day 10 hours 59 minutes and 40 seconds.

More importantly for them they were 7 hours 37 minutes and 4 seconds ahead of FenêtréA-Mix Buffet.

Le Roux and Riou, on their trimaran, FenêtréA-Mix Buffet, finished second in the Multi50 class of the 13th edition of the Transat Jacques Vabre after crossing the finish line in the Bay of All Saints in Salvador de Bahia, on Thursday, November 16, 2017 at 15:26:23 (UTC), 11 days, 2 hours 51 minutes and 23 seconds after leaving Le Havre.

FenêtréA-Mix Buffet covered the theoretical course of 4,350 nautical miles at an average speed of 16.33 knots, but actually sailed 4,726 nautical miles at an average speed of 17.71 knots.

Arkema also broke the Multihull50 24-hour speed record as they kept they pressed home their advantage down the final straight. They sailed 568 miles in 24 hours traveled between November 14 at 10:00 UTC and November 15 at 10:00 UTC (the previous record of 524 miles was held by Ciela Village on the Transat Quebec / St Malo in July 2016). The record is awaiting confirmation from the WSSRC.

Latest ETAs

Multi50: Réauté Chocolat on Friday, November 17 at 09:00 UTC

Imoca: St Michel-Virbac on Saturday, November 18 at 18:00

Imoca: Easy as 1-2-3 As those behind toiled in the Doldrums, the podium was becoming clearere and the Imoca looks the one class where there will be no huge surprises – except that SMA’s performance without foils has been incredible. Still upwind with less than 700 miles to the finish, St Michel-Virbac has increased its lead to 80 miles on SMA. In third, Des Voiles et Vous! can finally breathe. They admitted to being relieved to see Malizia II caught up with the Doldrums, now 170 miles behind and only just getting going again.

The Doldrums strikes The Intertropical Convergence Zone has descended several degrees of latitude in 36 hours and trapping several unlucky competitors. West is best? Maybe two days ago, but not anymore. The boats with a westerly strategy were the clear losers today: Malizia II, Bureau Vallée 2, relegated to seventh position and Generali, watching La Fabrique appear in their rearview mirror

“We made no progress from last night,” confessed Isabelle Joschke, co-skipper of Generali. “We’re managing to stay calm but we have to find the exit.” Bastide Otio and Initiatives-Cœur have prospered, relatively – Bastide Otio have only made 164 miles in the last 24 hours, but that is 100 miles more than Bureau Vallée 2. They should now be able to escape from the pack on the south-east trade wind.

Class40: Compression; 3 become 5 It is only the beginning and the Doldrums are already promising to have an equally dramatic effect on the Class40. The ITCZ currently extends 500 miles north to south; “a historic Doldrums, we’re told” exclaimed Arthur Le Vaillant, skipper of second-placed Aïna Enfance and Avenir, his perennial good humor not failing, yet. Its vital quality when you are helming for hours in 35°C.

There are only 4 miles between the front three still, who have been averaging 6 knots over the last 24 hours. But now Teamwork40 and Région Normandie Junior Senior by Evernex, are just 15 and 24 miles behind respectively and have reason to hope that they will not lose their gains when the fleet decompress at the exit.

Phil Sharp and Pablo Santurde, Imery Clean Energy, still lead, just, and have clearly chosen to shift further westward than V and B and Aïna Enfance and Avenir.

Ultime: Under tow Lionel Lemonchois and Bernard Stamm, are safe on board the dismasted Prince de Bretagne and have been under tow since 09:00 UTC by the Brazilian Navy Patrol boat, Guaratuba, that came to their aid last night. The 80ft Ultime-class trimaran, Prince de Bretagne, dismasted yesterday evening, 93 miles from the finish line. The convoy is within sight and will arrive in Salvador de Bahia in the early evening.

Pit stop Eärendil (Catherine Pourre and Benoît Hochart) have arrived in Mindelo in the Cape Verde archipelago to repair its broken starboard rudder bracket. They found Thierry Bouchard and Oliver Krauss’s Multi50, Ciela Village on the pontoons of the small marina, which is still on site after their abandonment

Quotes from the Sailors

Lalou Roucayrol, skipper of Arkema, (Multi50) This is my ninth Transat Jacques Vabre, and before the start, I felt good. Two years ago, I had to make a stopover in Salvador de Bahia because the boat was almost cut in half and we had to laminate so we could re-start for Itajai and finish the race. We deserved this victory, we sailed a great race. We kept our foot on the gas, we were fast, it was a fight from start to finish. We had a great start, it’s crazy as it’s the first time we’ve sailed together, but Alex is reassuring to be with, and it relieved me that he agreed to go with me. A Transat Jacques Vabre, it’s a commitment, you sail at 110% of your maximum the whole way.

Alex Pella, co-skipper of Arkema (Multi50) The Multi50 is great! It’s an awesome experience, they are superboats. I worked my way through the instructions (on how to sail it) as we went along and I was happy to be here, this boat has huge potential. “We spent 10 days in our oilies, and when we removed them, it was right in front of the entry to the Bay (of All Saints), and we got hit by a big squall. The whole race we slept under the cockpit roof. It was a novelty for me, these boats are very lively, you have to keep hands on and your eyes and ears open constantly. My lucky pants never lose, I always take them, even though they’re not that beautiful anymore.

Race details – Entry list – Tracker – Facebook

13th edition of the Transat Jacques Vabre • Biennial doublehanded race now 24 years old • Two founding partners: the city of Le Havre and brand Jacques Vabre • Four classes on the starting line: Class40, IMOCA, Multi50, and Ultimate • Starting November 5 in Le Havre (FRA) for the 4350nm course to Salvador de Bahia (BRA) n 2013, and again in 2015, all the boats flew past Salvador de Bahia, sails filled by the trade winds of the south-east, under the tropical sun…One imagines that they dreamt of finally finishing their race in All Saints’ Bay. In 2017, it will be a reality!

After the start line and a coastal route as far as Etretat, the duos will head towards Brittany to get out of the Channel as quickly as possible, where the currents are powerful, cargo traffic dangerous, and a lot of attention is needed.

They will then enter the Bay of Biscay, where, depending on the position of the Azores anticyclone, they will either find downwind conditions, easy and fast, like for the last Vendée Globe, or tougher and slower conditions in the passage of some late autumn depressions.

Four hundred miles later, having passed Cape Finisterre, the northern Portuguese trade winds should propel them quickly towards Madeira, and then the Canary Islands, where awaiting them will be northeast trade winds, which could be strong or weak.

Passing close to the Portuguese coast, or offshore, to the east or west of the Canary Islands and then the Cape Verde islands – you have to choose the right options. The next goal is to establish your position for the crossing of the dreaded Doldrums, located a few degrees north of the equator. At this time of year, it can change position very quickly, extend or contract, because even after carefully studying of the satellite images, sudden squalls can develop and stall the competitors under a good shower without wind for hours.

This passage is crucial in the Transat Jacques Vabre racecourse. Further west… Further east… After the calms, rainy squalls, with too much or no wind… The final goal is to get out well-positioned enough to benefit first from the southeast trade winds and to cover the remaining 850 miles towards the finish,passing along the islands of Fernando de Noronha, along the coast of Brazil and finally heading northwest into the magnificent All Saints’ Bay.

This transoceanic racecourse from North to South is more demanding than a transat from East to West; it requires the skippers to have sharp tactical and strategic qualities, good weather training, to be in excellent physical condition to maintain a sustained speed in the trade winds… And to have a lot of patience to cross the equator.

Weight and displacement

C ause for confusion

Building hours for multihulls

Building hours can vary considerably from one yard to another, but also from one boat to another in the same yard, even when the designs are very similar. 

Building hours are difficult to nail down but we provide some pointers in this article.

How much do multihulls weigh? We provide some real world data and show how to put it to good use.

MULTIHULL WEIGHT AND LENGTH COMPARED

We'd all like our next set of wheels to be a cool sports car with room to pick up the kids from school, do a bit of shopping, and maybe make the occasional trip to the hardware store. But we understand we're going to have to compromise somewhere. Same with boats. First across the line will probably not be the most comfortable cruising boat unless it's big and/or expensive. 

But how do you decide how fast you can go without sacrificing too much room, or without having to go bigger and more expensive? The purpose of the information in these plots of boat weight against length is to give an indication of what's achievable in the real world for fairly conventional construction methods and materials, and a relatively modest budget.

A lot of the boats on the plot are well known world wide including the Seacart 30, Corsair 36, the Multi 50 Arkema, G32 Foiling cat, the Gunboat G4, an ORMA 60 and a typical Gunboat 60 (weight estimated) which is off the page in the top right hand corner of the first plot.

Comparison Data

In the interest of finding a standard measure by which to compare a wide range of multihulls we’re going to use the measured weight (WM) component of the OMR Rule because it provides us with a wealth of readily accessible and reliable data.

We have also included some weights of boats that have been measured for other rating rules using similar standard, or where we believe the weight figure provided is reliable.

WM is defined in clause 6 of the OMR Preamble as follows:

Weight of the vessel shall be measured with all fixed equipment and accessories which will be carried during racing as documented in the inventory but without crew, crew personal kit, or consumables, including water and fuel. The vessel must be dry and all bilges and lockers open for inspection.

The full text of the OMR Preamble can be found here.

The chart plots in this article are built on our data base which currently comprises 109 catamarans and trimarans, 97 of which we have official OMR weights to work with.

The big picture 22' - 60'

This is the big picture graph that plots the weight against length trend line for catamarans and trimarans up to 60' LOA and also includes a MOD70 which is off the scale to the right. The blue line is the trend line for catamarans which are represented by blue squares. The grey line is the trimarans. Some images to follow will zoom in on various parts of the graph so you can read boat names.

It's interesting that the plot lines cross over at about the 40' mark with cats becoming relatively heavier as size increases. We shouldn't try to read too much into this in terms of the weight of the bare structure. It's a natural consequence of cats being preferred for long term cruising in the larger size range while trimarans are the weapon of choice for ocean racing. They employ exotic materials, refined engineering and meticulous manufacture to achieve low weight. 

ZOOM BOX 1 - 35' TO 54' LOA

The plot above focuses in on the 35' to 45' size range. The three trimarans Arkema, Carbon3 and 3 Itch are all sitting well below the trend line. Three Itch is the only one of these three for which which we have an OMR weight. Jessica Rabbit is sitting above the line but we used a weight figure provided by Martin Fischer which is an estimate of sailing weight including crew and equipment. Jessica Rabbit would sit closer to the black line under an OMR measurement.

Arkema's number is the quoted "displacement". If that is the actual weight it's a very light boat for its size but if we were to draw a trend line for Gunboat G4, Arkema, the ORMA 60 and MOD 70 all of these four boats would be close to that line. They are also all quite high tech construction.

ZOOM BOX 2 - 35' TO 45' LOA

The six Stealth catamarans (shown by the red squares) which are built by Asia Catamarans in Thailand provide an excellent benchmark for a high performance lightweight cruising catamaran that doesn't use exotic materials or construction methods. Most of the these boats have carbon rigs and synthetic rigging and they employ carbon in high load areas but are otherwise relatively conventional in construction using foam core with epoxy/glass skins. The three Corsair 36 trimarans are firmly above the line even though two of them were built in carbon.

ZOOM BOX 3 - 22' TO 33'' LOA

This plot in the 22' to 34' size range is mostly made up of trailerables. Trimarans on the black trend line and grey triangles, cats in blue squares. We didn't have enough cats under 30' in the data base to reliably carry the catamaran trend line into this plot.

GETTING BELOW THE LINE

Leaving aside the fitout and inventory that goes on the boat (we discuss that in another article) there are three critical elements to a light boat; engineering, materials and build methodology.

Engineering is critical for understanding the loads on the structure, having a good knowledge of the materials properties and applying the materials accordingly. Connecting loads with material properties means that a close working relationship between the builder, the designer the materials people and the composites engineers is absolutely fundamental. Where this relationship doesn't exist the materials specification has to be more conservative. That's one good reason why light boats take more time, more expertise and more effort, and consequently are more expensive.

Material selection is critical for making sure things are as strong and as stiff as they need to be. Carbon won't make for lighter hulls but it will reduce the weight and provide added stiffness in load critical structures like beams, rigs and foils. PVC foam is the ideal core unless you go to honeycomb cores - but that puts you in a whole new price bracket and ups the build skills requirements.

Build Methodology involves good laminating practice; getting the right fibre ratios and resin cure times and achieving good secondary bonding. If the engineer or designer is not sure of the level of skill on the shop floor then once again the specification needs to be conservative.

All of the boats that we see below the line on these plots have been built with due attention to these elements and the further they are below the line the more they will have focused on these elements in the respective design and build stages.

Arkema Aquitaine Capsizes in TJV

• Matthew Sheahan
• November 11, 2013

The multi 50 trimaran has capsized 200 miles from Lisbon, Portugal during the opening stages of the Transat Jaques Vabre

At 2158hrs UTC Sunday evening (10/11/13) Transat Jacques Vabre race organsers of the double handed race from Le Havre to Itajai, Brazil received a call from Yann Elies the co-skipper of nearby FenêtréA Cardinal (0.5 miles away) to inform them that the Multi 50 trimaran Arkema – Aquitaine had capsized.

At 2204hrs UTC Arkema – Aquitaine’s co-skipper Mayeul Riffet also contacted the race director by Iridium phone to inform them that all was well aboard the capsized trimaran.

The two French skippers, Lalou Roucayrol and Mayeul Riffet, are safe. The boat is 210 miles to the west of Cascais, Portugal.

Equipped with survival suits, the pair of sailors are dry inside the trimaran and are working on how organize their rescue. Just now the sailors do not plan to leave the boat. They have activated their Argos beacon so their position and trajectory can be accurately tracked. Weather conditions in the area make organising a tow a consideration.

Yann Eliès co-skipper FenêtréA Cardinal reported this morning: “Last night we were racing downwind with Arkema in 17kts of wind, it had died a bit but came back stronger and so we had to be careful. I was inside and Erwan (Le Roux) was at the helm and then one moment he could not see their lights.

Mayeuel (Riffet) called on the VHF to say that they had capsized so we should be careful, we were less than half a mile away.

He said that Lalou was fine because he was the one who had been at the helm, and inside Mayeul was well. I asked him if he wanted us to stop, he replied no.

I called Sylvie (Viant, race director) and told her what had happened. I think there must have been a technical problem.”

Arkema 4, a floating lab, takes to the watert

The new Multi 50 is the result of a close, intense collaboration between Arkema and the Lalou Multi Composite shipyard, which have been partners for eight years. With recyclable resins, new adhesives, clean energies and more, there are many innovative materials and solutions to complement the bold architectural choices.

The entire deckhouse/cockpit was made from a composite based on recycled Elium ® resin. The cockpit, which is 80 cm lower than on the other Multi 50s, offers protected maneuvering. For better visibility in all sailing conditions, the cockpit and deckhouse are fitted with glazing in Altuglas ® ShieldUp ® Flex PMMA, the first flexible sheet in the world, which can be installed without thermoforming and was developed by Altuglas International, Arkema’s subsidiary. This acrylic glass is five times more shock-resistant than traditional PMMA and considerably more lightweight. With a scratch-resistant, water-repellent coating, it offers remarkable optical qualities. Developed by the young French company Powertech, the latestgeneration lithium batteries use our Kynar ® technology, which increases energy storage capacity by 50% with no increase in weight compared to the Arkema 1 trimaran. Combined with a larger surface area of photovoltaic panels installed on the front outrigger arm, the system delivers a fully autonomous energy supply to on-board equipment without emitting a single gram of CO 2 .

As with the floats and the outriggers, the structure and bulkheads were assembled by structural bonding using Bostik’s methacrylate products. These highstrength glues have an elongation capacity that is six times greater than epoxy adhesives.

Our Elium ® resin wins the Pierre Potier prize

At a ceremony attended by Agnès Pannier-Runacher, French Secretary of State for Economy and Finance, Arkema was awarded the 2020 Pierre Potier prize for its Elium® liquid thermoplastic resin, a disruptive innovation on the composites market that is used to make 100% recyclable wind turbine blades.

ARKEMA : Heading for performance: Arkema steps on board Lalou Roucayrol’s trimaran with its innovative materials

Arkema-Région Aquitaine, the trimaran of skipper Lalou Roucayrol, is taking part in the upcoming Route des Princes race. A veritable « Formula 1 craft of the Oceans », this multihull was built with materials and technologies developed by Arkema that help optimize its weight, strength and therefore performance. This project represents a vast testing ground for Arkema's innovations.

It took eighteen months for this experienced skipper - who came second in the previous edition of the Route du Rhum , the most famous transatlantic race - and his crew to design and build this 50 ft (15.2 m) multihull. This has been a unique boat building project in Europe, in which Arkema is the main sponsor and a supplier of innovative technologies, two of which are in fact on board.

The cockpit window and the glazing shielding the two helms are made of Altuglas ® ShieldUp nanostructured acrylic sheet, which combines outstanding optical properties with exceptional resistance to impact , UVs and abrasion .

Furthermore, many of the boat's components were assembled with structural glues from AEC Polymers, a company in which Arkema recently acquired a 60% stake, and which uses the Nanostrength™ nanostructured block copolymer technology. This technology delivers an unrivalled breaking strength - elasticity compromise in the adhesives, thereby eliminating the need for a composite layer and reducing the overall weight.

The next official competition for Arkema-Région Aquitaine will be the Route des Princes race (Valencia - Lisbon - Galway - Plymouth - Roscoff) scheduled for June 9 to 31. It will then take part in the Transat Jacques Vabre in November, the overriding objective remaining the 2014 Route du Rhum .

A global chemical company and France's leading chemicals producer, Arkema is building the future of the chemical industry every day. Deploying a responsible, innovation-based approach, we produce state-of-the-art specialty chemicals that provide customers with practical solutions to such challenges as climate change, access to drinking water, the future of energy, fossil fuel preservation and the need for lighter materials. With operations in more than 40 countries, some 14,000 employees and 10 research centers, Arkema generates annual revenue of €6.4 billion, and holds leadership positions in all its markets with a portfolio of internationally recognized brands.
