I don't know what the Nacra class rules allow but I consistantly am able to right my Supercat 20 with a 12' beam and 33' mast by myself and I wiegh about 140lbs. The Supercat utilizes a side shroud extension which allows the upper hull to come over center of effort to right the boat. But!!! You must use a captive mast/ball system to prevent demasting. I've righted my boat in all conditions including the first Texas Two Step with 28 -33 mph winds and 8'+ waves! I can right this boat faster than any other boat I've sailed and when you KNOW you can right your own boat you can push it that much harder with cofidence. If any of you are going to the Ruff Rider Bandit Run, I'll be glad to show you how it works. Simplicity at its best!
