SUPERYACHT HALL OF FAME

BLACK PEARL - 108M OCEANCO

At 108m in overall length SY Black Pearl is one of the largest sailing yachts in the world and one of the most anticipated superyachts of 2017.

MARI CHA III - 44.7M SENSATION YACHTS

The famous Mari Cha III made her shining debut after a refit in Palma, Mallorca in June 2017. The 44m Sensation Yacht has had a rig extension of 3m, as well as, all new Stratis ICE sails with modern-looking square tops.

The yacht was fitted with a full wardrobe of high performance ICE sails, created at Doyle Sails 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. The modern-looking sails are a performance upgrade that will give extra area and allow more control of the twist. Stratis ICE is 11 times stronger than steel, weight for weight. ICE is remarkably light, durable, performs well under temperature changes and is made in an environmentally friendly, solvent-free process.

ICE is a new generation UHMWP sail fibre first applied to the marine industry by the Doyle team, and tests have shown an exceptionally high resistance to flex fatigue, with ICE retaining its initial shape longer than other sail membranes.

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 workload, 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.

SAILING YACHT A - 144M NOBISKRUG

Sailing Yacht A was built at the Nobiskrug yard in Germany, where she was fitted with the world's largest carbon masts. Equally important are her colossal sails that have been designed to cope with extreme weather conditions. Commissioned by Russian entrepreneur Andrey Melnichenko, Sailing Yacht A is one of the largest sailing yachts ever built. Full details of her interior are yet to be disclosed, but it is understood that she will feature an underwater observation pod and cruise at 16 knots, topping out at 21 knots.

Doyle Sails Salem released a behind-the-scenes video that shows how the sails on the 142.81 metre Sailing Yacht A were made. As this video shows, the three sails were bonded together at the company’s facility in Salem, Massachusetts, before they were carefully adorned with the yacht’s emblem. The sails were hoisted for the first time last year during sea trials off the coast of Kiel, giving us the first glimpse of the full scale of this monumental project.

PERSEUS 3 - 60M PERNI NAVI

After over two years of design, engineering and construction, Doyle Sails was able to fit sails on the impressive new Perini Navi Sloop, Perseus^3. The sail inventory, produced in Salem, USA, is one of the largest and most complex ever assembled. 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 sqm).

From the onset, performance was the clear goal of this project. Doyle Sails 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. 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.

ELFJE - 46M ROYAL HUISMAN

We've enjoyed the challenge of putting together a sail package that meets requirements of long distance cruising, with the odd regatta thrown into the mix. Working closely with Rondal, the rigging manufacturers, we've provided a main and mizzen with integrated reefing, designed for high performance with the boom rolling system which is being being manufactured by Rondal.

The roller headsails are comprised of blade jib, owners staysail, heavy duty delivery staysail, than a reacher/code 0 which is set on a removable furling torque stay to reduce windage.

The downwind inventory is made up of a full running AP gennaker and mizzen staysail; both of which have been crafted to perform well in Bucket racing with full crew, as well as under regular cruising conditions.

From the start of the project, our team had worked closely with the yard and designers. The early involvement approach has resulted in a design-led sail plan emerge that will meet requirements, with sail crossovers, integration of the sail and boom package, ease of use and low maintenance factors. Being involved from the start of the project has meant the Doyle team has been able to change the initial specs for an optimal end result beyond expectations. Early load analysis, aero analysis and FEA work have been worked into decisions on deck layout, mast loadings and overall loadings, reducing the chances of changes later in the build and so streamlining the build process. Working with other companies on the project, as well as closely with the yard and designers, before the build has begun, has allowed potential roadblocks to be identified and solutions found before the issues have manifested.

MALTESE FALCON - 88M PERINI NAVI

The owner, Tom Perkins' comments on Maltese Falcon's success,

“The Maltese Falcon has written a new page in the history of yachting, the DynaRig is no longer an experimental concept. Everything worked as engineered and the yacht achieved some remarkable numbers: hard on wind in 15.8 knots true, at 38 degrees relative wind angle. We sailed with no fuss or strain at 10.5 knots. On a close reach at 60 degrees relative angle, the speed (still at knots 16 true wind) climbed to 14 knots. The balance is, essentially, perfect–with weather helm never exceeding 0.6 degrees on the wind, or 2.5 degrees on a fast reach. The angle of heel was around 15 degrees, but in a puff, once touched 20 degrees. The leeway angle was well under 5 degrees (without the dagger-board in place). Since it was our first day out, and we wanted to be careful, these results were achieved with the topgallants and the royals furled–so we expect even better numbers in further tests. The maximum loading on the masts never exceeded 50% of our (very, very conservative) limit, so we have plenty of room for some even better results.

There were no untoward effects from the revolutionary rig. The automatic tacking worked smoothly in all wind strengths–tacking takes only 1.5 minutes, and curiously, she tacks quite readily in light winds, perhaps even easier than in heavier air, (because the wind force against the rigs, when backed, increases with the square of the wind velocity). Jibing is almost trivial and, to a passenger, virtually undetectable.”

M5 - 75M VOSPER THORNYCROFT

Mirabella V is the largest sloop in the world: the single-masted vessel is 75-meters long (247 feet), and that mast also happens to be the world’s tallest, with the world’s largest main attached to it. The scale of Mirabella V’s sails required novel engineering, taking full advantage of Doyle’s extensive superyacht experience, from material development to novel construction techniques.

Mirabella V’s mainsail measures 1,200 sqm (12,900 square feet). Building and designing Stratis membranes for this sized boat facilitated the need for a new view on the engineering and safety margins. Tyler Doyle modeled the loads using Doyle’s combined CFD-FEA program and designed the structural load paths to best address the enormous loads that this boat will generate. The Stratis main was built in Doyle’s custom built 32,000 square foot superyacht manufacturing facility in Salem, MA.

The batten development for Mirabella V was largely a question of optimization: at the required batten stiffness, what is the maximum toughness that could be achieved while minimizing weight aloft? The "Compression Spring Battens" clearly demonstrate Doyle Sailmakers’ commitment to durability and toughness.

KOKOMO - 58.4M ALLOY

Kokomo hosts a complete inventory of Doyle Stratis membranes designed and produced in New Zealand, and easily boasts many records in sail construction and sizing world wide. At 2,227 square meters (23,971 square feet) the Gennaker is thought to be the largest sail ever constructed at the time.

The working inventory comprises of a total of 3,038 square meters (32,688 square feet) of Stratis membrane sails, and many innovations in sail handling systems and detailing. The Mainsail has a custom designed boom furling system that utilizes the conventional bolt rope system of the Southern Spars, but also a self loading batten car system jointly designed and tested by Doyle and Southern Spars over the last 18 months, which addresses many of the weak points of boom furling systems with the advantages of full battens in a yacht of this size.

INDIO - 30.5M WALLY

From the first communication on what sails we desired for INDIO to the final fit and sea trial, Doyle exceeded my expectations: design discussion, detailing, aesthetics and customer service. INDIO is now a faster and safer boat to sail on… not to mention she never looked better!” - Captain Mark Fliegner, S/Y Indio.
