Phill, I have a question about your sailplan. Not a criticism, just a boat design question.

If you look at the two current production boats shown within this thread, the Opti and Hobie Bravo, you see that both use a "catboat" arrangement where the mast is far forward on the hull (Hobie Wave as well). Your traditional catamaran arrangement places the mast at midships offering a tiny tramp (~4-5 feet long) with the skipper far astern of a skeg boat's center of floatation. Also, your low boom is kind of a deck-sweeper for a training boat. There must be some other issues with boat handling in the catboat rig that made Hobie choose the Opti catboat plan. What are the advantages of a long-footed main as in the Opti vs the higher aspect Phill-plan?
