I obtained a Venture 21 that had been neglected for 5 years. When I got it home and blocked up the hull I discovered a crack 1.5 to 2 foot long (one leg of a v shape). The crack appears to go through the hull. Can I repair this well enough to restore the hull integrity or will it always be weak. I have another Venture 21 in good shape. Is it worth attempting a repair or should I scrap it and sell the parts. If I scrap it, what do I do with the hull?
