The U.S. Coast Guard has published structural guidelines applicable to aluminum vessels 60 to 135 feet in length having speeds up to 24 knots. They apply to vessels that are similar in hull form to passenger/cargo crewboats used in the offshore oil industry.
Titled Navigation and Vessel Inspection Circular 11-80, Structural Plan Review Guidelines for Aluminum Small Passenger Vessels, the guidelines are intended to facilitate local Coast Guard review of plans for such boats by providing a uniform and relatively simple step-by-step procedure for evaluating the structural design.
Free copies may be obtained by requesting NVC 11-80 from the Commandant (G-MP-4/14), U.S. Coast Guard, Washington, D.C. 20593.
