Doyle Sailmakers Delivers Sails to 60m Perini Navi Sloop Perseus^3

Perseus^3

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 CFD Analysis

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 LogoPerini 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.

Main and BoomThe 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.

Shockwave Wins Caribbean 600

Shockwave at Redonda.  Credit Tim Wright/photoaction.comGeorge 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.”

RORC Caribbean 600, 2014“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.

Stratis ICE Nominated for DAME Award

Stratis ICE FIberDoyle 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.

Doyle Sailmakers Secures Largest Order to Date

C2218 With Blade JibDoyle Sailmakers, based in Salem, MA, has recently announced that it has been awarded the contract to supply the complete sail inventory for the upcoming 60m performance sloop under construction at Perini Navi.  The inventory encompasses a staggering 10,200 square meters (110,275 square feet) of sail area including what will be the world’s two largest spinnakers.  The yacht is scheduled for completion in early 2014 and will make her debut at the 2014 St. Barths Bucket.

The order reinforces Doyle’s commitment and expertise in engineering some of the largest projects in the Superyacht industry including the sails aboard Maltese Falcon and M5, two of the world’s largest and most sophisticated sailing yachtsEssential to the success of this program will be the contribution of Doyle CFD’s analysis which is being used to model all aspects of the sail shapes and loading, completely integrating data from the boat’s hull and rig in real sailing conditions.  This will ensure that the sails as well as the associated hardware are all up to the task of propelling this yacht through the water. 

CFD Analysis of 60m Sloop

CFD & FEA has been performed to quantify loading and refine shapes in all the sails.

After several months of discussions, the final inventory was decided on after reviewing a number of possible combinations with an eye on smooth sail crossovers for an aggressive racing schedule the boat has planned.  For upwind sailing, the boat will have a 840 sqm mainsail which is complemented by a range of headsails – a reacher, a blade jib, a working jib, and then a Code 0 for light air conditions.  The upwind inventory will be constructed of Doyle’s proprietary Stratis membranes which have proven themselves on many of the world’s most glamorous Superyachts.  This technology will enable Doyle’s engineers and sailmakers in Salem to construct high performance sails with minimal weight.

DownwindDownwind is where the boat will really shine.  “We looked at every material available for these spinnakers and realized that there wasn’t anything in existence that would deliver the performance we were looking for,” explains CEO Robbie Doyle.  “We partnered with Dimension Polyant to develop a new high-performance Polyester spinnaker fabric that is reinforced with Dyneema for durability and burst strength.”  The new cloth allows the sails to be light and soft like a traditional spinnaker yet has tensile strength on par with other, heavier options.  The addition of Dyneema to the cloth will ensure that the sail resists tears, essential to success on the Superyacht racing circuit.  The boat will have two spinnakers, one measuring in at 2448 sqm and the other at 2170 sqm.  In addition, she will be equipped with a 643 sqm spinnaker staysail set with a top down furler.

“With this project we are fortunate to take everything we have learned in the last 30 years on both Superyachts and Grand-Prix race boats and put it all together in one package,” comments Doyle.  “We are extremely excited to be working with the project management team at Perini Navi, Future Fibers and Ron Holland Design to see this through its completion.” The order caps a string of good news for Doyle Sailmakers in the Superyacht arena, highlighted by the recent debut of the 50m Sloop Ohana, new inventories for the 52m Prana, 45m Artemis, and the launch of the 40m Perini Navi Sloop State of Grace with a full Doyle inventory.  When the 60m performance sloop launches next year, it will be spectacular to see her perform.
