I would look at the hobie wave or if you need something bigger hobie getaway with mast float. The nacra 5.0 or 5.7, prindle 16, g-cat 5.0 type boats would be ok choices too but will be less forgiving than the wave or getaway. I went from racing keelboats to sailing my Nacra 5.0 and while that experience has helped the catamaran is very much a different type of sailing, I rented a Getaway before getting my boat and the Getaway will feel lightning quick compared to any big keelboat.
