or wrinkles, and marked its edge with the side of a pencil; I also marked the locations of the dots on the ribs, transferring the plank shape to the tape. (Figure 13) I then stuck the tape down on a piece of 1/64- inch plywood, connected all the dots to make a fair curve, and cut out the plywood to make a template. It is important to mark the bow end on the template and one point in the center, typically one of the ribs near the middle of the boat, so the template can be put back in the same place as where the tape was. Planks can assume some funny shapes and it is not always obvious which end is which. If you do this, you may fi nd that some adjustment to correct the fi t


might be needed. I then used the template to make a pattern, as before, and from that duplicated four planks—one for each side of both models. Making the other planks for the rest of the plank runs was done in exactly the same way. For the fi rst model (the one that would show how caulking was done) I only bonded the planks to the ribs, not edge to edge with each other, and I spaced them apart by about 0.005- inch with a thin shim.


Once all the planks and the washstrake (which was made basically the same way) were in place on that
