How to Make a Keel for a Duck Boat
- 1). Cut two 3/4-inch-by-11/4-inch strip of marine plywood running the length of your boat. Coat the edge of the boat's hull with a generous application of fiberglass epoxy. Join the plywood strip to the epoxy.
- 2). Apply epoxy to the flange -- outer edge -- at the seam. Place the second plywood strip along the seam. Clamp the plywood strip in place at the front, middle and rear of the boat.
- 3). Cut piece of plywood 4-foot-by-6-inches, rounding the edges with sandpaper.
- 4). Apply generous application of hardening epoxy each end of the plywood. Affix it to the bottom edge of the boat.
- 5). Screw a self-tapping galvanized screw into each end of the plywood at the point of connection to the hull's edge. Coat each screw with the epoxy. Allow the epoxy a day to cure.
