RE: A real STARTBOARD LONGBOARD???
Wish it had a centreboard. :-(
Problem with a fin is that it tends to be too small at low speeds, and it tries to capsize the board when it starts planing. Oh, and you have to walk out to launch. The lack of a centreboard annoyed me on the Serenity and it would annoy me on these boards.
Having a fin is fine, if you only sail in deep water, aren't really interested in going upwind in light winds or reaching planing speeds, and don't mind a high-aspect shape that tends to stall when being used by beginners.
