- Could an equivalent to a stripper be built using birchbark instead of strips? How about gluing up a form using strips, then waxing it and gluing up a layer of birchbark? Is it possible to lay fiberglass over something as rough surfaced as birchbark? If so, it seems like (for some hull shapes at least) the birch bark with a layer of fiberglass on the outside could be pulled of the forms, then fiberglassed on the inside, then finished off like a regular stripper.
The only big problem I see with this is getting the birchbark fiberglassed without air pockets and without having to lay the resin on so thick that the canoe weighs a ton.
