If the canoe is longer than a standard plywood sheet, how do l make up the plank lengths?
Because the planks are longer than 8′ (2440mm) they need to be made up out of 2 or 3 pieces of plywood. The way we draw out the plank shapes for canoes up to 15’10” (4.8m), the planks are joined in their centre (mid point) – this can be done with a scarf join but typically for home DIY construction a simple plywood butt strap or glass butt strap is used – l like the glass butt and this consists of a glass tape in epoxy resin applied over the join on both sides of the join – the planks are simply butted together, the glass tape applied, the resin allowed to cure then the plank is carefully turned over and the tape applied to the remaining side.
