Really appreciate all of the suggestions!
@jcalvinmarks; I don't intend to completly avoid a capsize at all, as its a huge part in sailing, and creating something that could do this would also put huge forces on points in the boat also. The main aim would be to keep the boat in control and stable as much as possible especially in heavy weather. I'll look into the detachable or a possible retractable bulb.
@PaulfromNWOnt, what do you mean by a 'set of amas?' It definitly sounds like something I should be looking into!
@ftldiver, had looked into pontoons! Thinking maneuverability may become an issue? Outriggers sounds like it could be viable, but, would you need on on each side, because it would only be effective on a certain tack?
