Here are a few more renderings of that particular hull, and the original BIC pen concept development sketch. Should be somewhat self explanatory looking at the images; The design idea we termed the 'aqua hull' evolved for the need to have a 'float-in-dock' that allows guest tenders to enter, but without the need to keep flooding and draining the dry dock... also the trim and stability remains the same if it always is open to the water. The morph takes place at the chine underwater, so the hull looks completely like a nomal monohull except from aft. The keel of each pod is off centre (outboard) making the deepest part of the pod as far outboard as possible to also increase stability. Vee sections at the morph point, and a tapering flat run as it goes aft, allow the pods to still provide lift. A trim-tab could be configured to deflect spray away from the dock bay. Tenders could be stored port and starboard and lowered to the centreline of the vessel, this further reducing change of trim, as seen on most Superyachts today where the boats are sent outboard. Hope that explains it more clearly... we dont have all the answers yet, as it was just an idea and we reverted to a more conventional hull for the SABDES 70.. However, when I was a kid I saw a 15' plywood model (in 1982) of a wavepiercer cat in Hobart, with an extended shaft on its Johnson motor so it could reach the water... that was the start of Incat wavepiercers.
