thanks matt
i put bolts through it, and it hold it. the crack was on the keel line about 1 meter long. my method worked but the transom broke aswell on the port side half way up,in two places, im not steaming it but i will when i make up 2 new sides cos the other one is stuffed, but im goin to make something like a tent with gas stoves under it boiling water, my boss said he use to do it in the 70's and he just bent it up with ropes on the ground, any who, im buying more ply and cedar and start over.
cheers
matt
