My first windsurfing guru (and He Who Taught Me To Jibe) Dasher has been telling me about a super-easy to use sail for SUP windsurfing. Check this out:
1. The sail rolls up on the mast (no mast/luff sleeve threading).
2. No downhauling.
3. The boom folds down against the mast when not in use (no attaching/detaching from mast)
So to rig, you roll the sail out from the mast, raise the boom, tie off the outhaul and go. How cool is that? Watch the video to see (and to see the sail on the water).
