Wow, that boat must not have been in too goo of shape in the first place if you ripped through the sail. Once I was trying to keep up with a friend in his Nacra 6.0 we were doing 20 or more knots and a wave came over the fronts of the hulls and we went over forward. I landed on the sail but I didn't rip through it. In fact, for several seconds after the flip and before it sagged all the way to the water it was pretty solid, i had to walk off the edge of it and jump into the water. It kind of reminded me of those of those ninja movies where they run across the water with the cloth thing. Anyway, what i mean is. I'm pretty sure sails are supposed to be a little more durable than that.
