I've already patched one hull where it sat at the edge of a lake for 3 years and wore a hole through by rubbing the sand every time a boat went by. The rear crossbeam has a hairline crack that I might fill in with a weld. The bridle is missing also, but I would guess you are using that on your creation. Both of my tramps are shot also. Jib is gone, and one boomless mainsail is fair, the other is shot. It was a rental alright. The more I assess the thing, the worse it gets, but I've got all winter to fab stuff together and get it going.
So anything you arent using from your Gcat might be usuable to me. Let's make a deal.
