USCG documentation must be renewed on an annual basis. This includes all vessels over five net tons that are documented with the U.S. Coast Guard (USCG). Owners of documented vessels must complete a renewal application and pay the applicable fee to maintain their USCG documentation for another year. The U.S. Coast Guard (USCG) takes the expiration of documentation seriously and imposes a number of penalties for those who have let their documentation lapse.Depending upon the specific circumstances, those who have allowed their USCG documentation to expire may face one or more enforcement actions including fines, vessel detentions, and potentially worse.
