We were racing at CORK (Kingston, Ontario) when a p/s collision between Solings resulted in one of them sinking. Other racers at our club have been damaged during races where contact between boats occurred. (One boat was hit by a trawler in the fog.) Sailing magazines often show pictures of the gaping holes that the pointy ends of our craft are capable of making. Do any of you guys carry a crash mat or cloth for covering over a holed hull so you can stay afloat long enogh to get to safety? I am thinking of having our sailmaker do one up, and am wondering what shape might be the easiest to deploy and the most effective, should the need arise.
