The SeaRail-19’s Revolutionary Folding System

Weighing in at 7 pounds

The SR-19’s revolutionary folding system is just one of many engineering innovations incorporated into this Nigel Irens' design. The folding system allows the boat to be folded, unfolded, or the entire beams/float system to be de-mounted in literally seconds. The folding system is a key structural component while remaining extremely lightweight and completely hidden under sail. An evaluation of an on-the-water folding system was found to have negative effects on a trimaran of this size. Using the latest Naval Design and Engineering 3D Modeling software, we identified several safety and performance concerns with the traditional on the water folding strut system.

Safety - The first major concern with the traditional strut system was turtling (on the water rollovers) because of a much lighter platform and narrower folded beam compared to larger tri’s which use this system and a mast standing 34 feet off the water, the probability of a rollover in the mildest conditions was astronomical. This was a real concern with more and more boat launches separating the ramp from the dock, not allowing one to simply walk the boat on and off the trailer, but to now motor back and forth increasing the risk of a rollover. With the incorporation of our new design, the SeaRail-19 can be motored straight onto the trailer with no stability issues. We also reviewed the safety issues with raising and lowering the mast in the parking lot on both a narrow folded boat and a wide unfolded boat. It was determined the unfolded boat (like the SR-19) offered a higher degree of safety.

Performance - The negative effect of the traditional strut system on the performance included extra weight, hydrodynamic drag, and hull shape. We estimated the traditional strut system manufactured to fit a small tri, consisting of 4 upper struts, 4 lower struts, 24 pins, 32 lower brackets, 8 upper brackets, 100+ bushings, 100+ nuts and bolts, 16 backing plates, and extra glass reinforcement, to be more than 200 additional pounds (nearly 1/3 the fully laden weight of the SeaRail-19). Weight is the most critical component in performance and handling of small trimarans. Our complete, highly engineered, SeaRail-19 folding system weighs less than 10 pounds and offers the ability to not only fold and unfold, but to de-mount as well. De-mounting comes in handing for winter storage in a standard home garage or shed which typically is not accessible to tri’s with fixed strut systems due to the height of the beam ends. 

On smaller tri’s the distance between the underside of the beams and the surface of the water is greatly reduced, limiting the mounting surface area on the main hull where the lower struts attach. The lower strut becomes a real risk for hydrodynamic drag, not to mention the spray it generates.

Change in hull shape - the traditional strut system is a very precise system and requires very flat mounting positions on the hull. Again, because of the limited space between the underside of the beam and the surface of the water on small tri’s, the change in hull shape to accommodate the lower strut mounting brackets near the waterline will interfere with the hydrodynamic flow greatly reducing performance. Neither of these are issues with the SeaRail-19 folding system. The system is completely hidden within the beams – allowing the SR-19 to maintain its high performance hull shape and allowing water to flow unrestricted from bow to stern.

We are in no way condemning the traditional strut system which has been successfully used on larger tri’s and truly feel the system has allowed trimaran sailors a convenient method to reach new destinations. We simply found the system posed very serious safety concerns and had a negative performance value for our SeaRail-19 program.

The SeaRail-19 program had an excellent 2014 with 10 boats now delivered and 5 scheduled to arrive in the Midwest this Spring. We are totally committed to building the most affordable, high quality, and high performing, One~Design Trimaran fleet on the market. With a team compiled of some of the highest-regarded individuals in the multihull industry and over 2 ½ years of on the water, development the SR-19 has evolved into a very dynamitic watercraft.
Offering an unmatched power-to-weight ratio with a fully laden weight of only 700 pounds, upwind sails of 258 sf and a 278 sf spinnaker totaling an impressive 536 sf of sail. The 19 is the total package – whether it’s day sailing, camping, or racing, the 19 is like no other.
SeaRail Manufacturing - In early 2014 we established a manufacturing agreement with Triac Composites. Triac is a world class, state of the art, composite manufacturing facility owned and operated by Paul Koch (former owner of Corsair) and James Sganzela (former Operations Manager of Corsair).
Triac Composites is also manufacturing the new Melvin & Morrelli Rapido 60 Cruising Trimaran Both Paul and James have over 30 years of high volume multihull manufacturing experience. They are the best in the business; consistently delivering the highest level of quality. Triac’s current build capacity for the SR-19 is 10 boats per month with the ability to double that, if required.

New Midwest Assembly Site - In an effort to keep the retail price to a minimum, an assembly site has been created in the United States, Midwest Region. Boats in the North American market can now be picked up in the Midwest. This effort will save owners approx. $2,000.00 in shipping costs from Asia, import taxes, and unloading/reassembly fees. Last summer, new owners arrived from California, Florida, Wisconsin, and Canada to take delivery of their new SeaRails. With 100% of the hardware purchased and installed in the USA we’re now able to reduce the initial deposit on boats ordered in North America from $10,000.00 to $5,000.00.

Striving to Obtain Ultimate Performance - In November world renowned multihull sailor and high performance sail designer Randy Smyth spent a day sailing on the SR19. Based on his insightful input, we’ve made a few adjustments to enhance performance without overpowering the boat.
We made changes in rig tuning to reduce heeling, improve helm balance, and make the sails even easier to handle. Plus, we designed and built a longer bowsprit and redesigned spinnaker to further improve downwind performance. The SR19 will now be offered with a Smyth Sails Package. Randy’s impression is the SR19 is a very exciting design which will fill the void in the One Design niche market and still offer plenty of fun for the family. He is looking forward to spending more time on the water. Thanks Randy, can’t wait to go for a blast with the new larger chute!
2014 Boat Show - In December, Don Wigston and the Windcraft Multihull Team displayed the SeaRail-19 at the St. Petersburg Boat Show. The show was a great success generating a huge amount of interest. Patrons were amazed with the SR19’s overall size, the simplicity of the folding system, its light weight, and, most of all, its affordable price tag.

Despite the horrific weather in the Northeast the New England Boat Show is OPEN and the SeaRail-19 is on display . Bob Gleason from The Multihull Source shared some awesome photos from the show. The boat show is being held in the Boston Convention & Exhibition Center and runs from Feb 14-22. Come visit Bob and Ira at the show and ask about the SR19 Boat Show Special.

Don Wigston of Windcraft Multihull has provided photos and the GPS track from his latest sail on his new SeaRail-19. Thank you Karlene Gentile for the beautiful photos.
Don’s comments and GPS data LINK.
Wind was in the 8-11 knots range.
Unfortunately I forgot to active the recording until we had almost completed our windward leg. The track starts at the green triangle. From there we go upwind for a while, then bear off onto a close reach where our speed gets over 12 mph, then we slow down while rolling out the spinnaker, then reach our peak speed of 14.8 mph. I had no compass on board but from the track it looks like we are jibing through 90 which is pretty good in this relatively light wind. With more wind that angle will close up some.
