ABSTRACT:
A method for building lapstrake boats without use of a strongback and molds, and without the need to cut bevels on the strakes. The two-dimensional shape of each strake is determined and the strakes are cut to these shapes. A groove, or rabbet, is cut in the bottom inside edge of each, but the bottom, strake. The strakes are fastened or clamped so the top edge of each plank fits into the rabbet in the bottom of the adjacent strake. This has the effect of holding the strakes in alignment. The joints are filled with epoxy or other cementitious material making a strong stiff bond. One or more frames, bulkheads, or other interior components may be inserted as needed to maintain the strakes in the desired shape.
