I, too, would have to say no. Here in Blighty one of our sea rescue organisations is the RNLI. It's a charity, relying on donations to fund it's boats, equipment and fuel costs and operates with volunteer crews.
That said, the USCG, as the regulatory authority, can investigate any incidents requiring their, or any, assistance and, if found to be caused by incompetence, neglect or misconduct, can then prosecute or raise action against the company or it's officers.
