I've done 2 now. I read the instructions, here and on Yahoo (more carefully the 2nd time ). The 1st time, I used a small electric leaf blower and got bubbles at the bailer and around the top of the daggerboard trunk. I realize my method may have caused one or both of these leaks. I have fixed both leaks. On my 2nd test, i used a bicycle pump with a needle, stuck through duct tape over the vent hole. I got no bubbles anywhere, but I don't think I ever had much pressure in the hull, because there was not a good seal at all around the needle where it went through the tape. I also have an air compressor available.
How do YOU do your leak tests?
