Strip-built

[1] Also known as cold molding, the strip-built method is commonly used for canoes and kayaks, but also suitable for larger boats.

In a small boat, there will be just one layer of strip-planking, but larger vessels may have two or three layers which, (being a pre-shaped marine ply), forms a light, strong, and torsionally stiff monococque.A modern development of this construction procedure is "radius chine plywood", a method devised by yacht designer Dudley Dix which gives a fair hull that is both light and stiff.

The canoes are constructed by gluing together 1/4" x 3/4" strips of wood over a building jig consisting of station molds that define the shape of the hull.

The forms are cut as a series of cross-sections of the final design and set up along a "strongback" or another solid base.

Working primarily with wood is much more pleasant for the builder than building exclusively with fiberglass, which can cause irritation and respiratory problems.

Also, for a one-off constructor, it makes little sense to build a female mold; it is simpler and cheaper to manufacture a wooden jig that may be discarded afterward.
