Gunwale rails and rub rails are next. You can use layers of plywood or fancy colorful woods if you plan to use a clear finish to show off your work. Build up the layers until you get to the final thickness required, per the plans. Rip 1 for each side of boat starting with a 45mm wide piece stepping down 5mm for each 10mm of thickness. Cut out pockets for and install the corner blocks next. Form and shape the rails to the required shape and thickness and you are ready to remove the boat from the Jig. We used a hand planer for the rough shape and finished with a belt sander. It will now hold its shape and dimensions. The jig can be used as a cradle to support the boat as you work on it either upside down or right side up.
