We've accepted asymmetric fins, so moving on to the whole board is a logical step. The physics of sailing on one tack is so asymmetrical it's highly unlikely a symmetric hull is the best way to do it.
This suggestion is working on the principal of moving the lifting vectors closer to the one line. It uses Oldie's idea of offsetting the mast base so the sail could be more effectively raked overhead for vertical lift. It's starting to morph a little towards a kite board as far as lift vectors are concerned, but it's still a windsurfer, any of us could hop on and sail away.
The fin could be fixed at ~75 degrees or back-foot-adjustable on the fly. It could be spring loaded and use a handbrake type ratchet mechanism. You could crank it on to lighten the hull load in flat water or ideal conditions, or kick the ratchet and ease back foot pressure to bring it more upright if the tail got too lively in rough conditions. The hull is stepped port to starboard to reduce planing area at speed, but still keep the planing length long for control.
Like a kite it probably sails best windward rail down. We currently try and trim a bit on the leeward rail for max speed. Maybe that's a fin angle thing rather than a hull thing?
The sail would be a bit in your face but with the fin kicked to 90 deg it should work on the other tack.
