I am new to this forum, been on a few others but this one seems better. Anyway, down to the problem; I removed my boat from the trailer in my back yard, sea eagle 166, to modify my trailer ( electric winch fitted for launching and retrieving on my own off a beach ). unfortunately doing this i damaged the lower edge of the transom, where it meets the underneath of the hull. I have taken a chunk of the gelcoat off down the matting. The chunk is about 2 inches long by around 1/4 to 1/2 inch wide. Any ideas as to the best way of repairing this. I don't know as yet if water is seeping through to the inside of the hull as I have not tested it! I have read a few other threads and know not to use car filler, I have done some filling on the top decks with a gelcoat filler, would this be OK?
