15 years ago in Lapland (it’s a catamaran with rigid narrow skeleton):
I think catamaran is a good idea and especially if you can make it work with an inflatable frame. One thing to consider: the two bow waves of the hulls can merge to a higher one between the frames and add drag plus get you wet. It can help to toe in the hulls a bit, so that bows are closer to each other than the sterns. Maybe an adjustable test frame first (two by fours + straps or anything) to find out a good hull placement and then cutting the ‘captain’s bridge’?
