Good morning, Bill: Thanks for the info. I wish I could leave it in the water for a few days, however, our first big snow is due tonight. Might not be any more sailing until spring thaw next May. I spent 20+ years in SF. Belonged to a sailing club in Oakland and had access to 24 - 27 boats for the Bay. Too mean for me. I didn't realize how treacherous it can get. Anyway, have many large reservoirs plus the great salt lake to choose from. Where do you sail? Any good maintenance tips? I have never had a fiberglass boat. My last was a 16' Swampscott Sailing dory, a traditional wooden boat. The M-15 has many spider cracks on the deck, seat corners, lower deck, etc. Any product that will seal these. They are very minor cracks. Thanks for any ideas and tips. Tom
