How To Build A Duck Boat

This is a step-by-step article on how to build a duck boat. Building a duck boat is not a big deal and is mainly used for fun and sport.  This article should help you with the basics of building your own duck boat.

Items you will need:  

  • Saw
  • Putty knife
  • Drill
  • Furniture scraper
  • Wire
  • Three Sheets of Marine plywood (1/4-inch thick)
  • Two gallons of epoxy resin with 205 hardener
  • Six oz of 423 graphite (For mixing epoxy)
  • 60 ft. of 40-inch wide fiberglass tape
  1. Build the hull.  The hull is the body of the boat.  There are two bottom sections and four side sections that should be made of marine plywood.  Lay a coat of epoxy on the sections with a paintbrush and smooth the coat with a scraper.  Then apply a second coat of epoxy and wait for it to harden.
  2. Attach the hull bottom and sides to a block.  The block will need to be covered in epoxy before connecting the sections.  Place the block inside the sections, at the back of the boat.
  3. Join the sections.  The bottom and side sections will be drilled together. Using some wire, stitch the pieces together to develop the general shape of the duck boat.  Put dabs of epoxy on the interior seams using a putty knife. Wait a few hours for the epoxy to harden.
  4. Remove the wire.  Apply another strip of epoxy along the seams.  Place fiberglass tape over the exterior seams.  Place no more than two layers of tape.
  5. Attach a 3/4 inch x 11/4 inch marine plywood from each end along the top edges of the hull.  Place another strip of epoxy along the edges of the hull.  Place another strip of plywood on the outer edge of the duck boat.  Then coat it with epoxy along the seam.
  6. Make the keel.  The keel is a flap or fin that helps stabilize and direct the duck boat.  Cut a four foot long piece of marine plywood and round off and sand the edges. Drill a hole a couple inches in diameter at the end near the back of the boat, which will be used to tie down the boat.  Apply thickened epoxy to both ends of the keel in order to connect it to the bottom of the boat. Then wait at least 24 hours before using in order to allow enough time for the epoxy to get thickened.
  7. Make final touches.  Scrub the boat with soap and water.  Make sure it is completely dry before you add a coat of varnish or paint.  This will help protect the bottom of the boat.  Apply a coat of epoxy and graphite mix.  This will help when you have to drag the duck boat over rough surfaces.
