Beginning to dream again/do some long term planning about building a boat:
Do any of the suppliers still make 4'x12' plywood?
I did a search and couldn't find any.
I would look into scarfing if it would be taking stress. If not, a back plate and 5200. Look at the West System on line, teriffic info. I helped a loacol bay man do it for a work garvey. Still going over 25 years.
