Mari Cha III has completed 5000 miles in just over a month of cruising with her new Doyle Stratis ICE sails, and her Captain Christian Lay has given us his take on how the new additions are performing under pressure.
The yacht was fitted with a full wardrobe of high performance ICE sails, created at Doyle Sails New Zealand’s Auckland loft, and the 44-metre yacht has been putting her new sail inventory through its paces. With the light, durable sails, Mari Cha III has found no loss of stability in arduous elements, delivering better performance and longevity.
“One of the big things we have noticed is how much easier the sails are to use than our previous ones. They set really easily and hold their shape so well,” says Lay.
“All the little details that we customised for this boat have made sail handling and manoeuvres, such as reefing, so much easier. The boat is very clearly faster. The service leading up to, getting hold of and then commissioning the sails cannot be faulted.”
Doyle Sails New Zealand’s Matt Bridge says the company enjoyed the process of producing the high-performance sails for the yacht.
“This was the first set of Doyle sails for Mari Cha III and working on such a well-known yacht was a really satisfying experience for us,” says Bridge, superyacht sails coordinator, Doyle Sails New Zealand.
“There was also a nice synergy for us, given that Doyle Sails New Zealand’s own Mike ‘Moose’ Sanderson, sailed onboard Mari Cha III during her record-breaking TransAtlantic crossing in 1998,” says Bridge.
ICE is a new generation UHMWP sail fibre first applied to the marine industry by the Doyle Stratis team, and tests have shown an exceptionally high resistance to flex fatigue, with ICE retaining its initial shape longer than other sail membranes.
“Dealing with the mizzen staysails and big code sails is now really easy and we can get rid of the 900 square meter Code 0, in about 10 seconds, which allows us to sail the boat harder and more aggressively with a smaller crew,” says Lay.
“We have already done 5000 miles with them in a little over a month and had every configuration possible in winds up to 40 knots. There have been no issues with stretch, chafe or wear. We have pushed them downhill with boat speeds into the mid 20 knot region and then done big round ups in big breeze to get them down. The new batten system hasn’t broken one yet which is a big improvement for us.”
“In short I think it’s fair to say that we are pretty bloody happy with them and I am now thinking about which other sails we need to buy for the upcoming adventures. Oh – and for the first time – we have some decent sail bags that are strong enough, big enough, which have enough hand holds and look cool with the names on,” ends Lay.

Doyle Sails offers Stratis Sail Art, which allows photo quality printing on sails for the first time ever.
Doyle Stratis Sails, already offering a high degree of customization between fiber combinations and surface types, offers an entirely new customization in printing of any graphics on the sail surface before the sails are laminated, resulting in the most-detailed sail art to date.
Having long realized the need to offer special images for customers and commercial sponsorship, Doyle has created a number of stunning sail graphics over the years, but has taken it to the next level with Comar Yachts’ Shadow – the first yacht to have been fitted with Stratis Sail Art sails. The 100’ yacht, launched in 2011, was fitted with Doyle Stratis Membranes complete with a photo-quality octopus finished by the team at Doyle Sails Palma.
Moving away from the traditional technique of painting directly onto sail, the new procedure allows the the image to be printed directly onto the sails surface with incredible accuracy before the membranes are laminated in New Zealand. The printing process means that detail, form and subtle nuances are transferred to the sail with unerring accuracy, making for the most detailed sail art to date. In the case of the Shadow this meant an octopus stretching down the sail on each side – carefully aligned to stretch across the Main and Jib.
The mosaic-like print has layers of colour, shapes and overlaid details which bring the two octopi to life as the sail fills. Despite the layers of detail, the end result is noticeably lighter than the sail would be if the image was created using the traditional approach of layering paint by hand – something which at this size would normally add 10-15kgs to a sail.
Lightness is a known characteristic of Stratis. Forming the base for Stratis Sail Art, the underlaying Stratis membranes have a formidable reputation for high performance and resistance to flex fatigue.
The unique Stratis Sail Art process doesn’t compromise the sails’ integrity, compared with the traditional paint process which can result in brittle sail membranes. Full photo images can be translated onto the sails – drastically increasing the appeal of sails as a billboard to sponsors – with a high definition finish that’s as effective close up as it is from a distance.
‘Stratis Sail Art is the next generation in sail art,” says Doyle Sails New Zealand managing director, Chris McMaster.
“It adds negligible weight to the end product, while maintaining the integrity of the sail and performance Stratis is known for.”
Doyle Sails New Zealand’s Auckland loft is the biggest in the southern hemisphere and is well-known for its innovation; creating Stratis, Stratis ICE and a range of other products. Now, adding Stratis Sail Art to its stable of products, the Doyle Sails New Zealand team is proud to not only be able to offer sails which perform unlike anything else on the water, but look unlike anything else on the water.

After over two years of design, engineering and construction, Doyle Sailmakers has fit sails on the impressive new Perini Navi Sloop, Perseus^3 in La Spezia, Italy this past week. The sail inventory, produced in Salem, Massachusetts, is one of the largest and most complex ever assembled, and will provide a breathtaking and unprecedented racing and sailing experience for the owners and crew. Perseus^3 stands apart from her peers with both her carbon clearcoat mast – one of the world’s tallest – and for her A2 Spinnaker – the world’s largest sail – measuring in at 28,010 square feet (2,602 square meters).
Two years’ worth of work came together in two days in Italy, as the Mainsail, Reacher and Blade Jib were fitted for the first time. The yacht will now begin her series of sea trials and sail system trials, gradually adding in the remainder of this spectacular racing inventory.
From the onset, performance was the clear goal of this project. Doyle Sailmakers was involved with the process from the beginning, working with Ron Holland Design, Perini Navi and Future Fibres to optimize every aspect of the sailing experience. The mast was carefully engineered to assist with the massive sail area of the yacht. From Doyle Sailmaker’s end, the size of the sails entailed a novel approach to both engineering the materials and sail handling. Taking it one step further, Doyle CFD (Computational Fluid Dynamics) addressed the challenges of properly balancing the load on the three headstays, with the additional Code 0 Torque Rope, while still maintaining an acceptable headstay sag for the racing requirements of the yacht. Working with the engineers at Perini Navi, Future Fibers and Germanisher-Lloyd, Doyle CFD helped establish the proper balance and stability of loads on the stays and the sails.
Doyle Sailmakers has long been known for its innovation and this project is no exception. With prior experience coming from M5, Athos and Kokomo III, Doyle Sailmakers constantly adds new innovations and continues to enhance the overall sailing experience. New developments for this project include an inboard end fitting for the battens that isolates both the forward compression of the battens as well as eliminating vertical shifting. This new design ensures that the custom Perini Navi slides will enter the track without compromising the luff tape – essential to reliable sailing with rollboom mainsails. Additionally, the working jib, hoisted on a removable inner forestay, necessitates innovative soft hanks that automatically change in diameter as the sail is lowered to allow the sail flake over the larger diameter torque tube at the base of the torque rope.
Perseus^3 is the first vessel from Perini Navi to include a bow sprit – enabling the yacht to carry a number of massive downwind racing sails. The two spinnakers are among the largest sails ever made. The A2 measures in at 28,010 square feet (2602 square meters) and utilizes over 3,200 yards of cloth. Initially, there was no existing fabric capable of delivering high performance, light weight and a ‘soft hand’ for handling. The solution was an extensively tested fabric that blends Polyester with Dyneema – giving the cloth high strength as well as tear resistance.
The Code 0 will also fly off the sprit, and is being furled on the largest Top Down Furling Cable ever created by Future Fibres. After previous success with Top Down Furling for Code 0’s – with the cable in a contained luff sleeve – this was selected for Perseus^3 to enable the crew to quickly furl the sail and stow it easily. The Code 0 has been constructed using Doyle Sailmaker’s proprietary Stratis process, with curved radial seams to follow the path of the loads and enable precise shaping, high strength and minimal weight.
Perini Navi Group, a leader in the design and construction of many of the world’s largest sailing and motor yachts, has long been one of Doyle Sailmaker’s most important partners in the superyacht market.
“We first worked with Perini Navi on Andromeda le Dea in 1990, which at the time was one of the most technologically sophisticated yachts afloat. We have been pleased to work with them since on some of their highest performing and noticeable projects – from the majestic 88m Maltese Falcon, the racing oriented 38m Sloop P2, or the signature purple sails of the 50m Ketch Baracuda,” said Robbie Doyle, CEO of Doyle Sailmakers. “We always enjoy working with Perini Navi as they share our passion for sailing and innovation, and are always working to deliver the very finest product to their customers.” In just this last year, Doyle Sailmakers has been fortunate enough to deliver sails to the 56m Ketch Audace, 52m Ketch Tamsen, 50m Ketch …Is A Rose, 50m Ketch Silencio, 45m Sloop Clan VIII, 40m Sloop State of Grace and currently has sails underway for the 56m Ketch Asahi and 45m Sloop Helios.
The mast and boom for Perseus^3 were produced by Future Fibers, and at 75.8m the mast stands among the three tallest rigs ever built in the world. “We have managed to produce a tube with a perfect exterior surface and a flawless Clearcote gloss Carbon finish with zero filler – which can add up to 3 per cent to the weight of a mast,” according to Future Fibres. The mast weight is optimized at 16.4 tonnes. Similarly, the 23.4m carbon fiber furling boom has been manufactured using pre-preg carbon improving structural performance and weight, compared with standard wet–laminate construction. The boom features a new mandrel furling and locking system, as a result of extensive testing and prototyping.
In order to ensure safe sailing, Perseus^3 will feature an exclusive Rig Load Monitoring System that monitors the loads acting on the sails and rig components through a series of strain gauges.
For the handling and control of the impressive sailing system, Perseus^3 features the new generation of Perini Navi captive winches and furlers. The jib winches pull a maximum load of 30 tonnes and have a maximum line speed of 40 meters per minute. Electric variable speed motors and furlers, duly synchronized and monitored by the Perini Navi Automated Sail Handling System, dramatically improve furling and deploy times while speeding the tacking and jibing time by over 75% compared to vessels of the previous generation.

Superyachts from around the world were on hand for what turned out to be perfect conditions at the 2014 St. Barths Bucket Regatta, spanning three days from March 28-30. Doyle Sailmakers’ staff were sailing on many of the boats at the event. Doyle Sailmakers’ founder and president Robbie Doyle was on-board the 125’ S&S designed Axia, Chris McMaster and Justin Ferris from Doyle New Zealand were onboard the new 164’ Dubois Ohana, Quinny Houry from Doyle Palma was on the 148’ Perini Clan VIII, John Baxter from Doyle Chicago was on-board the Holland 112’ Blue Too and Matt Bridge from Doyle New Zealand was on the 122’ Dubois Moonbird.
The conditions for the week were near perfect with 15-22 kts. Fresh off her win in the BVI’s, Moonbird placed second in the Mademoiselles Class, sporting a full set of new performance focused Doyle Stratis ICE sails. She was followed in third by Blue Too, who in addition to her third place finish, also took home the Alloy Trophy for the best performance by an Alloy yacht. The 31m Dubois Sarafin finished in fourth place flying a new Doyle Stratis jib.
In the Grand Dames Class, the 50m Perini Navi ketch Silencio won the last race in her class to put her into third in her division. Silencio was using a brand new Doyle A2 spinnaker for the regatta, measuring in at nearly 13,000 square feet and featuring a massive Lion inlay. She finished 1 point clear of the new 40m Perini Navi Performance sloop State of Grace who was powered by a full inventory of Doyle sails.
Congratulations to all of the winners and looking forward to the 2015 St Barths Bucket.

The 2014 superyacht racing season started on a strong note, with Moonbird winning Class C at the 2014 Loro Piana Caribbean Superyacht Regatta & Rendezvous. Moonbird, built by Fitzroy Yachts and designed by Ed Dubois, is a 123′ sloop that was recently fitted with a new mast and Stratis ICE sails. Matt Bridge from Doyle Sails New Zealand was sailing with the team on Moonbird. Second place was the Oyster 100 Sarafin, and third was Tempus Fugit, a new 90′ sloop from Arkin Pruva Yachts – both of which carry Doyle sails.
In class A, the 164′ sloop Ohana placed third and Leopard by Robertissima was fifth with full Doyle inventories. Chris McMaster and Justin Ferris from Doyle Sails New Zealand were sailing onboard Ohana.
The next event will be the St. Barths Bucket, with racing starting on Friday the 28th. Moonbird, Sarafin and Ohana will be joined by other Doyle powered boats, including Axia, Blue Too, State of Grace and Zenji.

George Sakellaris’ R/P 72 Shockwave took the overall IRC win in this year’s Caribbean 600, correcting out to finish roughly 1 hour ahead of rival Bella Mente. After 600 miles of racing, Bella Mente, Rambler 90 and Shockwave crossed the line within 15 minutes of each other, after close racing all along that saw numerous lead changes. The win adds to Shockwave’s growing list of recent victories, highlighted by her Gibbs Hill Lighthouse Division win in the 2012 Newport-Bermuda Race and first in the 2013 Montego Bay Race. The overall IRC win was the highlight of a number of impressive finishes for Doyle-powered boats, with Line Honors for Bella Mente – carrying some specialty reaching sails from Doyle and featuring Doyle’s own Mike Sanderson as a helmsman, Botin 65 Caro, with a full Doyle Stratis inventory taking 5th overall in IRC, First 40 Lancelot II winning IRC Two with a new Doyle Stratis Mainsail, and the 62m Hoek Schooner Athos greatly improving on last years performance and battling it out with longtime superyacht rival Adela.
A grueling 600 mile race circling around many islands, with stiff breeze the whole time, the race places a premium on having a well prepared boat and crew. In anticipation of this year’s race, Doyle refined the sail inventory to make sure that the team would have the right sails, without carrying too many. Robbie Doyle, who in addition to managing the sail inventory served as Shockwave’s tactician for this race, explains the thought process, “We looked at the conditions that we were likely to see, and then when designing and building the sails worked to make sure that their ranges were as large as possible. Thankfully our Stratis process allows us to make some of the lightest sails available, so we increased the DPI’s a bit to ensure we could carry the same sails longer.”
“With the amount that conditions change in this race, sail changes can just be too costly. In the end, we used the J2 (Medium Jib) 95% of the time, and just twisted it off a bit in the bigger squalls. We only carried 3 jibs, which helped save weight.” Flying the same jib up the majority of the race allows the crew to stay aft and on the rail, keeping the boat moving. The other big change was adding a new Fractional Code 0. “After last year’s Montego Bay Race, we looked at our sail inventory and felt that the jump from the Jib Top to the Code 0 was too big. We built a new FRO to fill that gap. It was the workhorse of the race, as coupled with the Top Down Furler, we could leave it up, and just furl or unfurl as the conditions changed without any drama on the foredeck.”
Owner George Sakellaris was pleased with the results. “I have a great crew and it was an excellent race, lots of wind and the racing was very close. I have done many offshore races but this is the first time I have raced this one and it was against tough opposition. I think the winds were favorable to us and the Shockwave team used that to our advantage. At the end of the day, winning yacht races is all about the team performance more than anything else.
Robbie Doyle was similarly enthusiastic after the race. “That is what ocean racing should be all about. Beautiful racing between three very tough competitors, all fighting it out the whole way. A heavy-weight battle without a doubt – no question. I have had great moments in sail boats, but that was as much fun as I can remember. For 600 miles we were always in touch with each other, either up a few minutes or down a few minutes, and it all came down to the last beat to finish. It was like an epic tennis match.”
Next up for Team Shockwave will be defending her Newport-Bermuda Race victory in June.

Doyle Sailmakers is proud to announce that Stratis ICE has been nominated by the jury for the DAME Awards 2013. Overall winners are announced on the first morning of METS (Marine Equipment Trade Show), November 19th. Doyle Sailmakers will have a team exhibiting in the Superyacht Pavilion at Stand 10.715 , with samples of ICE as well as other materials from their product range.
The DAME is a prestigious competition for new marine equipment and accessories that is awarded based on overall design, build quality, functionality, and use of materials. To win the DAME is the ultimate accolade for companies and innovators, and all the nominations for the award are seen as trendsetters for the next generation of product development.
Stratis ICE is an entirely new and unique Ultra High Molecular Weight Polyethylene (UHMWPE) sail fiber that is a game-changing product for the sailing market. In summary it is lighter, more durable and stronger than any other sail fiber available. ICE is unique in that it is the first truly new fiber to be introduced to sailmaking in recent years; other traditional advances in sail technology have simply been a new application of existing fibers.
ICE provides weight reductions and elongation numbers equivalent to a sail made with 100 per cent standard modulus carbon, but without the durability issues that come with high carbon content laminates.
This flat ribbon fiber was originally used by the US military and Doyle Sails has secured the marine rights to the product and spent 4 years developing special adhesives and application techniques to turn this extraordinary fiber into a durable sail material. The fiber is ideal for use in the sail market as it exhibits very low stretch and creep, yet is lightweight, highly durable, and resistant to UV and salt.
Results for ICE have shown the highest resistance to flex fatigue of any sail product, with ICE sails retaining their initial shape and speed longer than any other sail membrane. This allows the Doyle design team to engineer sails much closer to their work load, and avoid over-engineering them in anticipation of future flex fatigue. Overall this makes ICE the first realistic alternative to carbon in performance racing sails.
Doyle primarily developed ICE to improve performance of superyacht sails. As superyacht sails got heavier and with higher loads – especially on yachts over 50m in length – the corners of the sail and the actual sail laminate needed to be very thick and heavy in order to be able to take the load of the sail. Use of the flat ICE fiber makes sails lighter and thinner, avoiding the heavy contour and texture in the membrane and eliminating the thick corner laminate that results from traditional membrane sails.
Although ICE offers so many benefits, the challenge for the sailmaker is that it is extremely slippery fiber and therefore very complex and difficult to work with: after a long development process Doyle has mastered the production technique required to use it. Prior to undergoing the standard Stratis lamination and laying process (unique and award-winning in its own right) the fiber is treated to make it workable; Doyle had to develop special polymers with low melt points in order to be able to laminate the fiber.
