How to Build Your Own Sailing Boat

Sailboats can often be seen on lakes and bays on warm, sunny day. Some of these boats were made by the owner in a home workshop. The method used by many of these people is called stitch and glue. Stitch and glue is a boat-building process that enables an owner to connect pieces of plywood with epoxy, forming a solid boat. This boat-building method can be used by most people to build a sailboat. Materials for the boat can be purchased at home improvement stores or online.

Instructions

    • 1

      Purchase boat-building plans. Take great care to determine the size boat desired. Important factors are the number of passengers and the distance traveled. Failing to build a boat that is large enough will be unsatisfactory, while building a boat that is too large can be a waste of money and time.

      Cut pieces of plywood with a jigsaw as directed on the plans. Use a cordless drill to place 1/4-inch holes in each adjacent seam and connect pieces of plywood with thin copper wire. When complete, there will be a boat shaped from plywood with copper wire connecting each seam. Additionally, cut your framing, dagger board framing and a mast receptacle. Use copper wire to put these in place in the proper location according to the plans.

      Mix epoxy according to the instructions on the can. Stir sawdust into the epoxy, making an epoxy paste the consistency of peanut butter. Apply epoxy paste to all interior seams in the boat with a spatula. Each epoxy pasted fillet should be approximately 2 inches wide and 1/2 inch deep at the center. Allow to dry for several hours.

      Cut the copper wires with wire cutters. Remove the wires with pliers. Mix additional epoxy. Cut fiberglass cloth in lengths to cover the epoxy fillets. Lay the fiberglass cloth on each epoxy fillet and use a paint brush to thoroughly wet the fiberglass cloth with epoxy. With several helpers, turn the boat over so the bottom of the boat faces up. Lay fiberglass cloth on the exterior seams and wet them in the same manner. Allow the boat to dry for several hours.

      Apply fairing compound to any indentations or errors. Allow the fairing compound to dry 12 hours and smooth with sandpaper. Apply additional fairing compound to any remaining indentations and sand with sandpaper. Repeat this process until the boat is completely smooth. Paint or varnish the boat as desired.

      Build the mast, dagger board, rudder and sails according to plans for the boat. Many boat masts can be made by gluing two 10-foot-long, 2-inch-by-4-inch boards together and using a sander to make the mast round and smooth. Dagger boards are normally made by gluing two identical pieces of plywood together with epoxy. The edges are then sanded and the dagger board is varnished. Rudders are typically created by attaching a 3- foot to 4-foot wood tiller to a piece of plywood. The rudder is then attached to the boat using door hinges. Sail systems can be built using lightweight canvas for the sail and 2-inch-diameter aluminum poles for the booms.

      Launch the boat and check for leaks. Cover any leaks with additional fiberglass cloth and epoxy. Cover the fiberglass cloth with fairing compound and sand. Prior to allowing passengers on the sailboat test the boat in all anticipated wind conditions. Gradually, add one passenger at a time while learning to cope with additional weight in the sailboat.
