All this talk about guns, and flares, and ball bearings/sling shots etc. is funny to say in jest, but it is not a viable option. We start that ****, and then the sailboats start arming themselves. Cold war all over again. Flags, education and notices seem like the only legal option. I actually have no hope for sailboats. I started this thread so we can maybe come to a consensus about unwritten rules of the water to keep things from getting ugly among fellow fisherman.......ie 7mm mags!
