We are so off the wall it doesn't really matter, but his maximum beam isn't affecting his centre of buoyancy. His maximum waterline beam may be however, and looking at the drawings I'd say its almost exactly between the two mid masts, almost directly above the centre of bulb...looking at his hull form under the waterline, I'd say the LCB is close to maximum beam at waterline. The waterline plane is almost aerofoil shape, hard to see at first. Still, wrong shaped hull whichever way you crack it, but I see scope to improve it hydrodynamics wise and keep the main thrust of the concept. Looks like it was done in Rhino or similar ? Can the OP measure the volume below waterline and see where the centroid is relative to the masts / bulb ?
