Jim gave me a great little jig he made up, with foam cutouts glued to a piece of timber at the correct distance for the rails (upper and lower, deck curves). I went around the board and marked up the rails on all edges so I had guides of where and how much to shave off.
I marked a clear 2.5 ft from the tail to allow for a knife edge rail. I marked this point on the rails as DO NOT SAND PAST HERE. Then I marked another grad line approx 6 inches away. this was to be the gradual transition from Hard to soft.
I started with the rails on the bottom and stopped briefly to take a photo of the rail profile. Then I kept motoring.
