Here are pics a canoe that I built a couple of years ago. It was from a design purchased from CLCboats. It was built using Stitched Lap Strake construction. Stitched because of the twist ties used to temporarily hold it together. Lap because of the overlapping half lap rabbets. And strake because that is what ship guys call the long strips. The plywood is Okoume which can handle the water problems. The gunwales are mahogany, and the seats are ash.
The 8 foot strakes were joined using 6 inch scarf joints to make them around 16 feet. I drilled holes in the strakes and used copper wire to slowly pull it all into shape. No forms were used. Then added the gunwale strips on the top, and the stretcher bar in the middle. I bought a gallon of epoxy and a half gallon of hardener in pump top containers. Two squirts of epoxy and one squirt of hardener into a plastic cup and then applied it with disposable foam brushes. Both the inside and outside were coated with multiple coats of epoxy, sanded between coats. Silica powder was added as a thickener to the fill the gaps of the lap joints on the outside of the boat forming nice fillets. Wood flour (sawdust) was added as a thickener creating a paste when needed on the inside when the end pieces were attached. The twist ties were removed and the outside was finished with marine paint.
The triangles at the end of the boat are dual purpose. They add strength and are also air tight. This makes two flotation devices used to keep the boat from sinking if it is capsized.
It now hangs in my garage and makes me smile every time I drive in there.
