Aluminum fishing boats are easy to build and customize. They are very economic compared to fiberglass boats since they do not require a mold to build. Aluminum is light, strong, corrosion-resistant, non-sparking, and easy to repair because it is weldable and can be cut with carbide tools. These boats last a long time, have good resale values, and have a competitive edge in performance.
However, aluminum fishing boats are vulnerable to pitting, electrolysis, and crevice corrosion. These limitations, experts say, can be overcome by the proper installation of dissimilar metals and electrical items. It generally takes 45,000 pounds per square inch (psi) to tear aluminum apart and 35,000 psi to deform it, compared to a chunk of mild steel that takes 60,000 psi to tear it apart and 30,000 to deform. Size for size, aluminum has a higher yield strength.
Aluminum fishing boats are not for everyone and not for all types of fishing. They are ideal for waters with faster pitching and rolling motions because of their lightness. An aluminum fishing hull built in the same strength, size, and standard as a steel-constructed fishing hull weighs approximately 45% less. Aluminum fishing boats can be constructed with the same structural weight as those made of steel and still be considerably stronger.
