RE: Board/sail combo for gusty flat water sailing
A note about the sail...more downhaul! If you're getting pounded by gusts, having whatever sail you're using rigged with more downhaul should help you convert those gusts into speed as opposed to abuse. All other things being equal in "on-off" conditions, I prefer to rig a little larger, and then rig that sail for overpowered sailing. Adjust the outhaul accordingly.
