Anyone can Build a Boat. Its that Easy

Just about anybody can build a boat using the Bowdidge Marine Design Plywood Composite system. This method eliminates many members that ordinarily require fitting, fairing, and beveling. Thus, it's ideal for beginners. A jigsaw and drill are about the only power tools required. The resulting boat is incredibly light weight, strong, and durable.

This quick and easy boatbuilding method consists of plywood planking panels cut to shape from patterns in the plans which are "stitched and glued" together at the seams. Such a boat can be assembled in a matter of hours after cutting out the parts.

The stitching is done with plastic electrical ties passed through small holes along seam edges. These are zipped tight to hold the panels together. The glue is then applied between the stitching and also on the inside in a cove-shaped fillet along the seams, along the outside and inside. After curing, the "stitching" is removed and the gaps filled. Then the hull is covered in glassed.

Plans for all our designs include instructions, material layouts, and material listings. In addition, the patterns provided are precise, since they're taken from the actual 3D modeling and CAD systems.
