I have wondered about the planning cat idea myself...Designing and building high performance sailboards since 1986 I can't see why some of the hull design learned from that venue couldn't be incorporated in a small cat...even sub 14 foot. After all if we can go 30 mph on a 8'-4" sailboard why couldn't a hull be made with two modified boards and achieve at least current cat speeds? I know someone tried it once with a kind of catamaran sailboard hull with a hard deck...don't know how successful it was...but one try does not prove or disprove the concept. Definitely takes thinking outside the box...
