We’d cut the hole n the deck to extend PG’s cockpit some time ago. A decision was made to make the after coaming raked as well as radiused so the first thing to do was work out what shape everything had to be. Design in situ by means of thin plywood templating and slender battens to represent coaming caps. This is quite an organic process really, but it enables everyone to stand back and have a good squint whilst giving very definite answers to questions about shape and dimension.
I used Khaya construction veneers to laminate the stock that would become that raked coaming, and in the lower picture you can see the start of the fashion pieces inserted under deck to provide structural backing.
