I have the Shearwater 16 plans and am just starting to scarf together sheets of plywood, cutting out forms, etc. The manual says the form locations are on the full size patterns for the hull pieces. They are not. Does anybody know where they go? There are 15 of them -- every foot starting at the bow or what? Seems like their placement in the cockpit area would be somewhat critical. Thanks for any insight you can share with me.
