"Feasible, biut there will also be tradeoffs in windage and perhaps waves hitting the beams if they are too far apart.   Depending on your requirements, it may work better to put a pop top over the cockpit and call it the saloon.  Sitting headroom inside when going upwind, standing headroom the rest of the time with zip on clears."   

Yeah I thought about pop-tops too, it could work out

I am mindful of windage, on such a short WW hull and in-keeping with decent deck clearance it starts to look a bit condo like pretty quickly. The catamaran experience with the same things highlights that difference in handling boats due to varied interactions of wind and water. That, and often they look like dogs.

I guess I either need to get more clever of consider a larger design which offers more scope.
