Coast Guard officials also draft recommendations for the transit of hazardous cargo by ship, such as liquid natural gas.
Among the activities of the Coast Guard is inspection of commercial boats carrying passengers for hire.
It was expanded during the 20th century to include the protection of ports, harbors, vessels, and waterfront facilities against accidents, negligence, and sabotage.
In the United States, the Coast Guard is responsible for evaluating, certifying, and credentialing U.S. merchant mariners.
