Searail Trimarans discuss the design objectives of their folding system

From the following press release on Searail Trimarans website:

Weighing in at less than 20 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.
