Shockwave wins Copa del Rey 2014

Shockwave ArialLaced with the Who’s Who of the sailing world, the Mini-Maxi Class (IRC0) in this year’s Copa del Rey regatta provided very close and exciting racing throughout the week long, 10 race event. Leading from start to finish was the oldest boat in the fleet – the Reichel/Pugh 72 Shockwave – skippered by George Sakellaris and powered by Doyle Sails, including her latest Stratis ICE headsails. This inshore regatta win complements the Shockwave Team’s offshore victories in this year’s Newport-Bermuda Race where Shockwave was the elapsed time winner, while sweeping 1st overall in the Gibbs Hill Division under IRC and ORR. In the spring of this year Shockwave won overall the rough and tumble Caribbean 600 Race.

The secret to Shockwave’s success has always been the combination of all aspects of the latest technology driven by a close knit team sailing the boat. Doyle’s CFD Team led by Tyler Doyle worked with Reichel/Pugh to fine tune the keel and bulb, and worked with the Future Fibre’s team to optimize the mast in terms of weight and windage. Similarly all sail decisions in terms of inventory, and shapes are done with in-depth CFD analysis with the CFD team working with the sail design team to analyze effects on performance and rating.

Shockwave Copa del Rey 2014

One of the latest advances for this regatta came from utilizing Doyle’s latest Stratis ICE fiber, which allowed the team to create a new jib which maintained the standard ultra-light weight requirements of the program while still maintaining its shape through a wide range, so that a single jib could be used from 10 to 22 knots.

Four out of the five Mini Maxi boats won at least one of the 10 races held, and the top three teams faced the last day separated by only three points. The title was decided in the final race with victory and championship for Shockwave with 19 points, and Hap Fauth’s Bella Mente, with a partial Doyle inventory, on 22 points, and Roberto Tomasini’s Robertissima III, on 23 points, completing the podium.

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 Line Honors in 2014 Newport-Bermuda Race

George Sakellaris and the team aboard the Reichel/Pugh mini-maxi Shockwave crossed the finish line off Bermuda’s St. David’s Lighthouse Monday morning at 5:34 race time EDT (6:34AM local time). Her elapsed time was 63:04:11. The close contest between Shockwave and her rival Bella Mente, Hap Fauth’s 72 foot Judel/Vrolijk mini-maxi, was a near repeat of the 2012 race, where both boats smashed the course record and finished with Bella Mente a mere 3 minutes ahead. This year, Shockwave led by seven minutes, after the two had battled head to head within sight of each almost continuously for over 635 miles. Although the boat for boat racing was close, Shockwave won comfortably on corrected time besting her rival Bella Mente by 1 hr and 44 minutes in ORR and similar margin in IRC.

As with the 2012 Race, Robbie Doyle sailed as the “stratitician,” working with the navigator, Andrea Visintini, the Tactician, Stu Bannatyne, skipper George Sakellaris and overseeing the sail program.

Doyle said, “There was a constant analysis and dialog onboard as the position of the Stream was fluid, and the weather pattern was also shifting. We had to hunt to find the (Gulf) Stream… we never found the 4 knot real road to Bermuda. It had broken up before we got there. Forecasters had predicted it might, but they suggested we might get there before it would start to dismember. The Stream was really breaking up pretty quick.”

“We tried some new ideas and ways to optimize the boat for the ORR rule” explained Doyle. “Bella Mente is a more powerful reaching boat than Shockwave so in order to defend our 2012 victory we felt we needed to improve our rating as we did not feel we could beat her in a reaching drag race which the Bermuda Race can often be. After a detailed weather analysis of the past 10 races over a 20 year period we made the decision to switch to a fractional spinnaker hoist. We designed and built a new full size Fractional Code 0 (labeled Super-FRO by the crew) to complement our existing smaller FRO. We only carried one free-flying spinnaker and then two Fractional Code 0′s.”   Both FROs were set on top down-furlers for easy sail handling and crossovers. The combination proved successful, as the powerful “Super FRO” carried the boat through some crucial transitions.  ”Surprisingly its best moment came when VMG running in 8 knots TWS into head seas with Bella Mente right on our tail. Even though she was carrying a full size mast head spinnaker we were able to open up on her with the more stable Super FRO.”

Doyle CFD worked on the analysis to ensure the corner loading was in line with the boat

Doyle CFD ‘s analysis was critical to ensuring the Super FRO’s success onboard Shockwave

“We had one day of practice with the Super FRO, during which we saw what a powerful weapon it could be, but also how much it really loaded up the sprit. We had Doyle’s CFD team working with Reichel/Pugh’s office to re-engineer the sprit to handle the sail, and the guys were reinforcing the sprit until 3am the morning of the start!  A total team effort to pull off this incredible result again.”

The win adds to Shockwave’s growing list of recent victories, highlighted by their division win in the 2012 Newport-Bermuda Race, the 2013 Montego Bay, and the 2014 RORC Caribbean 600 Race. Originally launched in 2008 as Alpha Romero 3, Shockwave has proven to be a dominant force in the last 3 years.  Doyle Sailmakers has been intimately involved in the boats resurgence, helping optimize not only the sail program, but also the mast and keel for a full aero and hydrodynamic package.

Robbie Doyle on the Bermuda Race: Strategy, Sails, & Crew Care

Robbie Doyle will start his 12th Newport Bermuda Race when the fleet leaves Newport on June 20th.  He is what he calls the “stratitician” on board George Sakellaris’ Shockwave, 2012 winner of the Gibbs Hill Lighthouse Trophy and the North Rock Beacon Trophy as top IRC boat in the race. We caught up with Robbie at the Doyle sail loft in Salem, Mass.

Q.  To get an edge on the competition, what should competitors, navigators, or tacticians be doing now to get prepared for the race in mid-June?

For all competitors, right now you should be reviewing the weather from past races and watching the Gulf Stream and surrounding eddies. Begin to get a feel for what to expect in terms of weather and determine how the Gulf Stream is setting up and moving. Don’t wait until two days before the race to do this. The Gulf Stream and accompanying meanders and eddies play a key role in the race so you need to know where all the key elements will be when you get there, not just at the start.

Q. As well as watching the Gulf Stream, how important are weather patterns and forecasts and why?

My first Newport Bermuda Race was 38 years ago and we relied on celestial navigation, and much of the weather was predicted by the navigator’s arthritis. The prevailing strategy was what emerged from past races. It was basically thought that you head 180 degrees until you get into the Gulf Stream, and then head for Bermuda.  Along with everything else, weather forecasting has gotten a lot more accurate but you still cannot trust the forecast 100 percent.

On Shockwave we are preparing with the goal of winning it.  So, currently, we are doing a study on weather data over the decades and we are basing our analysis on a number of factors.  The reason the weather predictions are so important is that we will decide on our sail inventory from our analysis. If we choose wrongly, or if I advise wrongly, that does not give me a warm, fuzzy feeling. These decisions of what sails to bring and what sails to leave behind are a huge factor in preparing for the race and can determine a great deal. We need to submit our rating by May 22 so most key decisions must be made by then.  We will make our macro inventory decisions then but exactly which sails come and go will be decided the day of the race. Despite all the technology we have, you never win the Newport Bermuda Race if you don’t make some big guesses and that is all part of what it takes to win the race.

 Q. Are there some factors that many competitors could take greater notice of as they consider their competitive strategy?

Yes, and it is about sail inventory. Read the ORR rules again or talk to your local sailmaker.  The rules have a clear effect on the sail inventory because with ORR rules you are rated with the spinnaker factored into your rating whether you choose to use one or not. You are rated based upon the minimum ORR area whether your actual spinnaker is that size or not.  If your spinnaker is larger than the ORR area your rating goes up, but not vice versa. Some teams will have a spinnaker on the boat that may be well under what you are rated for.  Similarly, you are charged for a minimum jib area and a cruising boat with a non-overlapping genoa is likely to be under that for jib area. It is very easy to miss these details and you should take time right now to figure out your sail inventory to your best advantage.

 Q.  What are some common pitfalls for competitors?

You want to make sure you establish your watch system immediately and stick to it from the start. I can’t emphasize enough how important it is to get into a rhythm and stay rested.  People tend to want to stay engaged or participating in the decisions even when they are off watch -but it is better to preserve your energy. You will need it.  Another pitfall is that you don’t rest on your laurels after you pass through the Gulf Stream. As a rule the sea state is calmer but people are tired and it is very easy to stop thinking strategically.  There remain a lot of tricky currents and decisions made in the final 200 miles of the race where it can be won or lost.

Q. What else have you learned about the Bermuda Race?

The more I learn about the race and the more I know, the less confident I have become about winning it. The Newport Bermuda Race is one of the most challenging races of all time. You have the Gulf Stream, with hot and cold air meeting each other. It is an oceanographic and meteorological laboratory and we are the RATS! It is really, really tricky. It is always interesting, challenging, and rewarding to take part in.

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.

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.

The Beat Goes On: Shockwave Wins 2013 Montego Bay Race.

Having proved her mettle for inshore racing, Shockwave, driven by owner George Sakellaris followed up her recent Key West victory  with a near record breaking performance in the 2013 Montego Bay Race.  Stretching 810 miles Ft. Lauderdale to Montego Bay, Jamaica, Shockwave and her crew were able to complete the course in an impressive 2 days, 11 hrs and 23 minutes and missed the course record by a mere 58 minutes.  On corrected time, she also won the IRC division.

SW with her Doyle Stratis Code 0

The race started in light wind that went down to 2 to 3 knots the first evening. The following day, Shockwave made big gains towards the record reaching along Eleuthera and Cat Islands, averaging 20 knots with her Code 0. After rounding the tip of Cuba she hit a high of 26.4 knots using her newest A4 spinnaker and was on pace to beat the record only to be thwarted by a lightening wind that shifted aft as she approached the finish, protecting the record set by Titan 12 in 2005.

The Reichel/Pugh designed, McConaghy built Shockwave is powered by a 100% Doyle Sail inventory tailored to match the boat’s performance curve using the latest analysis and insight from Doyle’s in-house  CFD and design team.  For this regatta, Shockwave was utilizing her 2-year old offshore race main – the same sail that carried her to victory in last year’s Newport-Bermuda Race. “The success of the sails we are using is a clear indication of the durability and strength of the Doyle Stratis laminates,” tactician Robbie Doyle pointed out.  The Code 0, an ultra-light Doyle Stratis sail with curved radial seams for super-precise shaping and strength, was used for about 50% of the miles sailed and once again proved to be the most versatile and easy to handle headsail in the inventory.  By combining practical experience with cutting edge design resources, Doyle’s team has been able to deliver sails that clearly enrich the performance of the boat and the crew.

Next Team Shockwave will head to the Mediterranean for the PalmaVela regatta in May.  Be sure to Like Team Shockwave on Facebook to stay up to date with her activities.
