This last picture shows the epoxied surface, which is now a curved line with a spiral twist - you can kind of see that in the photo.
Ill do the other side and then determine the final shape or line to cut the outside of the board. It will probably end up being a straight taper - narrow at the front and gradually getting wider toward the rear of the boat. I decided to reinforce the sides at each screw attachment point with another piece of 1/4" plywood. To keep it simple and light, a flycutter was used to cut some 1.5" diameter "washers" from 1/4" plywood. These were epoxied in place on the inside of the boat and held in place with a screw and a temporary duct taped block on the outside of the boat. I am not going to permanently attach these rails until the boat is out of the basement. Hate to add any unaccounted for width.
After a bit a trying different lines, a straight line did not work as it made the forward foot or so look like it bulged out due to the shape of the boat side. So I used a strip of plywood to create a curved line and cut it on the band saw and sanded out the bumps and saw lines it until I had a smooth surface.
I plan on putting a 1/2" or 2/4" wide stainless steel rubstrip along the outer edge.
