5-9knots.... that could be a wild ride if you are solo. You will definently not be wasting you time.

I don't want to scare you but the boat should be popping a hull up readily in 9 knots. But there are alot of ways to make it a little less crazy, travel out, crank on the downhaul.

Once you go cat you never go back! Nacra 5.2 (Elsies)#1499, running an inter17 spin!
