Strong Performance from Doyle Sails at 2016 St Barths Bucket Regatta

St_Barths_Bucket_v2016_logo_128In the increasingly performance-focused superyacht racing scene, Doyle Sails helped propel many yachts to the front of the fleet at this years St Barths Bucket, held off St Barthelemy from March 17-20.  In the end, Doyle powered yachts won three of the five pursuit classes that saw nearly 40 yachts competing.  The regatta saw the fleet sail three races around the archipelago, which challenges the yachts with close roundings around islands and rocks, making the imagery even more stunning.  This year saw moderate breezes for the first two days of racing, and then high winds and big seas in the final day to push all the crews hard to keep these massive yachts moving well.

Sailing Yacht P2

38m Perini Navi P2

38m Perini Navi sloop P2 continued her string of impressive performances with a win in Class B: Les Elegantes des Mers.  P2 has long been a superyacht regatta favorite, and just the previous week P2 won Class B at the Loro Piana Superyacht Regatta in Virgin Gorda.  Under new ownership this year, the boat has continued her impressive ways, and after P2‘s win on Saturday’s “Not So Wiggley Course”, which sees the yachts weave through a number of turns which requires multiple spinnaker sets and douses, tactician Tony Rey commented “The owner and his guests were so engaged and so into the race; everyone was excited.  Honestly, it’s what we came here for; these last two races have been some of the best superyacht racing I’ve ever done. We can’t wait until tomorrow.”  P2 has been carrying the same Doyle Stratis Carbon/Technora racing sails since 2013, and her consistent performance is a testament to the incredibly fast shapes and durability of the Stratis sails.

S&S 125 Axia beating upwind with her new Double Headrig Configuration

In Class C: Les Femmes des Mers 37.6m Axia won with an impressively consistent performance, winning all three races.  Doyle’s own CEO Robbie Doyle was serving as tactician for the regatta, and worked well in advance to help prepare the yacht for the regatta.  In order to keep Axia at the front of the fleet (they also won their class at last years St Barths Bucket) and optimize their rating under the ORCsy Rule, under which the boats are rated for this regatta, Axia went through an headsail development program to improve their tacking time and pointing ability.  The result was a larger staysail and enlarged Jib Top, in place of the original racing Genoa, which kept the yacht fast and nimble as they sailed around the island.  What might be most impressive  about this win is that the same Stratis Main on Axia has now powered the boat through six Buckets – helping the yacht win three of those – in addition to all her other sailing and charters.

56m Perini Navi Rosehearty

56m Perini Navi Rosehearty

In Class E: Les Grandes Dames des Meres 56m Rosehearty and 50m Ohana finished tied at the end of the final day, with Rosehearty’s wins in Races 1 and 2 breaking the tie in her favor.  After winning last year’s Perini Navi Cup, Rosehearty was fitted with a new A3 spinnaker and Mizzen Staysail to ensure that the boat could keep moving at full speed during the Bucket’s many challenging courses.  On the final day of racing, the big breeze helped push the massive yacht at 13.5 knots downwind, but upwind proved a challenge.  A fitting on the genoa furler snapped off in a puff, forcing the yacht to sail a good portion of the long upwind beat with just a staysail. Ultimately the genoa was partially unfurled to keep the boat moving steadily upwind to the turning mark.  Paul Cayard, serving as tactician on Rosehearty, commended the crew of Rosehearty all week, but was especially impressed on the final day “The crew did an outstanding job of dealing with today’s adversity and kept the maneuvers tight so we could preserve the fourth place we needed to win overall. A very happy owner and all concerned.”

The overall results of Doyle Sails this year are a testament to the continuing focus on performance and service from the team at Doyle. The regatta brings a strong team of sailmakers from Doyle’s lofts around the world to ensure that the yachts receive the full benefit of their sails. “I’m incredibly proud of our customers for the results in this year’s event, and it’s truly a testament to the team at Doyle we have assembled in order to help these yachts perform to their best” commented CEO Robbie Doyle.  “Our technology in recent years has continually kept our sails at the front of the fleet, but this year’s team onsite was the best we’ve ever had and helped get everyone across the line safely and quickly.  The results this year show both the grand-prix performance that our sails can achieve, but also the durability and shape holding of these sails over time.”

60m Perini Navi Sloop Perseus^3

This year saw Robbie Doyle and Glenn Cook from Doyle Salem on Axia, Andrew Schneider of Doyle Salem on Rosehearty, Peter Grimm of Doyle Florida East on Perseus^3, Quinten Houry of Doyle Palma on Clan VIII, John Baxter from Doyle Midwest on Blue Too, Nick Bonner of Doyle England on Surama, Simon Lacey of Doyle New Zealand on Emmaline, Matt Bridge of Doyle New Zealand on Seahawk, Alan McGlashan of Doyle Salem on Bella Regazza, and Mario Giattino and Salvo D’amico of Doyle Italy and Justin Ferris of Doyle New Zealand on Ohana.

Doyle Sailmakers is proud to have a long history as a sponsor of the Bucket regattas, and has established lofts in all of the superyacht hubs around the world to ensure excellent service for the world’s largest yachts.  Recently Doyle has delivered sails to many of the world’s largest yachts, including the 60m Perini Navi Perseus^3, which made her debut at St Barths this year, the 46m Royal Huisman Elfje,and the 89m Perini Navi Maltese Falcon.  In the coming months Doyle Sailmakers will deliver sails to the two largest sailing yachts in the world, both measuring over 100m in length.

Doyle Sailmakers Delivers Sails to 60m Perini Navi Sloop 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.

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.
