Summary

The Navy Secretary, or the Secretary of the department that runs the Coast Guard, may officially say that a U.S. vessel built for a special job cannot follow some international rules about lights, shapes, or sound signals without hurting its mission. If that happens, the vessel must follow the rule as closely as possible, the decision can cover a whole class of vessels, and the certification must be published in the Federal Register.
