I don't know if I've mentioned the time I was thinking about a boat that would be an M-hull design that consists of two parts — a diving platform/catamaran barge and a jet ski that docks backed into the bow of the barge.

In motion, the jetskis sets up a bow wave that is swallowed by the catamaran hulls. Maybe 8x13ft, that's the Golden Ratio.
