Looks like exactly what you want for rivers and confined waters, where you want more sail area up high to catch wi d that isn't blocked by surrounding topography/obstacles. Also gives excellent visibility down low: another plus for sailing in tight spaces. And the fact that it doubles as an awning? *Chef's 😘
Hi Tom, the spreader is connected to the mast using 3/8" polyester line. The mast cap is made of 2" hardwood ball, and a half of lacrosse ball (rubber) is under spreader. The rubber ball has some wear and tear after the season, would probably replace it with hardwood ball next year. Similar "universal joint" was also tested on a smaller sail (kayak in other video) and it works reasonably well for sunfish sail as well. I've just uploaded some photos, link in description. Happy sailing!
