Since I have not thought about the template method for this part I just looked around to see what I could use to help make a template... Stir sticks! I have a full case for mixing epoxy. I placed them to where they hit the deck and stapled them in place. It was removed from the boat and placed on a sheet of paneling to make my main template. I made my marks and ran a batten over it to draw my line. Cut out the whole thing and checked against the boat again.
I came pretty close to what I had in mind. Note that the width of this is to be trimmed down considerably once the length behind to the rear of the boat is cut and palced. The main part of this is to make the proper match to the curvature of the boat.
The template is close enough and with a small adjustment I made a copy onto 1/4" plywood for the installed piece. Some small amount of fairing and this piece is ready to copy for opposite side.
