Boat Projects - Stitch and Glue Tutorial
1 pdf

The stitch and glue boatbuilding technique is not new. It has been used for several decades world wide to build everything from tiny paddle craft to 30+ foot power and sail boats. Using software, the designer creates the hull in 3 dimensions and the resulting panels or planks are “unfolded” so they can be cut from 3MM to 5MM marine grade plywood in the case of canoes, sea kayaks and other small watercraft.

“Unfolding” the panels is the process of lofting or projecting the panel so that a set of three dimensional lines can be correctly recreated on a two dimensional surface. Fortunately much of the computational work is done by the computer. The plank lines from the design program are then brought into a computer aided design (CAD) program and measured for layout purposes. Planks are cut with a saber saw and small holes are drilled along each panel so they line up with the mating panels. As wire ties are affixed in holes along adjoining planks, the planks are “stitched” together, the intended hull shape is recreated and temporarily held together until it can be glued. The seams along the planks are filled with epoxy putty then the holes left by the wires are filled. The hull is sanded down and sheathed in fiberglass. The composite of the plywood and fiberglass creates a sturdy and durable hull.

No building forms or backbones are required saving the builder the time and material cost for that project. No special workshop is required. Many simple canoes and kayaks can be completed in less than 60 hours and material costs can be kept under $300 with some smart shopping. It is hoped that this article will help you understand the process more fully and help launch a quest for your own personal Sairy Gamp.
