I used the "internal chine log" method. anywhere you want two panels to join you put in a block of wood, 1" wide on the glued face, with one glued face on each panel and every joint oozing PLp to make sure it was full for waterproofing.
While I like it and it is waterproof, I don't know if it saved me much money over marine epoxy and fiberglass tape joints, and it is heavier than epoxy and glass. If I ever build another plywood tear it will be with epoxy and glass joints, that way no joint needs extra wood to reinforce it, and my spars could be made of 1/4" plywood. Super light like a modern stitch and glue boat, or airplane structure design.
I'll have to revisit some of my uncles gear and see if any of his books of trade are in there (restoration Shipwright). I remember the same technique on some of the smaller boats he had restored (the larger were all Pitch & Oakum sealed). Fibreglass was one option I'd looked at, but wasn't my first choice. LOL....I've used in the past, but we never seem to play nice 100% of the time, and my success has varied.
Thanks Rowert
