Is the hull strong enough so the Shoalsailer can be beached?
The Shoalsailer hull laminate schedule was specifically engineered for beaching. There is a layer of incredibly strong and abrasion resistant uni-directional Kevlar/glass hybrid that runs down the bow all the way to the lead keel. The composite sandwich core hull utilizes 3/4″ linear closed cell foam through-out to stiffen the entire structure without adding a lot of weight. The triaxial laminates on either side of the core provide amazing strength. While this hull will be impenetrable in normal beaching situations, in case of a high speed grounding on rocks, a watertight crash compartment under the V berth will keep the Shoalsailer afloat in a worst case scenario. Shoalsailers have been run up on the beach over twenty times during the video and promotional shoots in New England and the Keys sustaining only scratches to the bottom paint. How stable is the Shoalsailer? There are two ways to calculate stability. Using the traditional “hull only” formula, the Shoalsailer shows 29,000 foot
