ALUMINUM

Feature: Aluminum Boats Prove Their Mettle

By John Simpson, Editor, Aluminum Now and Michael Skillingberg, VP, Technology, The Aluminum Association, Inc. Aluminum has been used in the marine industry for more than 100 years because of its light weight and ease of fabrication combined with good corrosion and fatigue resistance. However, for much of the past 30 years, fiberglass has been the material of choice of North American boatbuilders, particularly for higher-volume production lines. Competitively priced compared with boats made from most other materials, fiberglass boats can also be made from standardized molds that reduce their construction time and labor. Aluminum alloys, which are specified for marine use, offer many benefits, though, too. Their high level of performance along with recent advances in aluminum cutting and welding is helping to reduce fiberglass' boats cost advantage, and the metal's utility for a wide range of boatbuilding applications is poised for reappraisal. Changing Image of Aluminum Boats "Aluminum boat technology is relatively new," says Steve Daigle, president of Daigle Welding & Marine Ltd., in Campbell River, British Columbia, noting that welded aluminum boats first came on the market en masse as recently as the late 1960s. Prior to that, riveting was the standard technique for joining aluminum sheets on boat hulls-a technique still used for many smaller boats that use thinner-gauge aluminum.
