I'm not really sure I understand the question here. Do you mean that you currently have the skin tacked to the caprail area and want to pull the metal around the hull to meet up with the keel, itself? If so, depending on thickness of metal, experience with welding and heating, and tools available my answer will vary according to the size of the job at hand. A fourteen foot skiff will have a different answer than a thirty foot displacement hull.

I await further information before I can try to be of assistance. Thanks.

Oops... For some reason your quarter inch material topic didn't register. Two questions... How rounded is the curve you're trying to shape? And is the vessel upside down or vice versa? It's a real pain in the butt pushing this thickness into the hull without previous shaping. It would be easier to do it in strips of two to four feet using jacks and a stiffback if you don't have access to an industrial rolling machine.
