ABSTRACT:
The hull of a wooden vessel is laminated and provided with an outer plastic skin which provides a hull of high structural strength, and protects the wood interior against rot and attack by marine organisms. In its preferred aspects, a skin of fabric-like fiberglass is chemically bonded (and preferably chemically and mechanically bonded) to a wooden hull constituted of wooden planking at least three-fourths inch in thickness by use of an elastomeric adhesive which, after curing, is capable of stretching at least twice, and preferably from about 3 to about 5 times its length, and the outer surface of the fabric-like fiberglass is saturated with resin, covered with a chopped fiberglass mat, cured, a fairing compound is applied to the exterior of the skin, and the surface is sanded and painted. The laminated structure is highly resistant to stresses produced by expanding, contracting and bending, particularly prevalent in thick wooden hulls, which tend to produce delamination between the skin and the working hull.
