The Passenger Vessel Services Act of 1886 (sometimes abbreviated to PVSA, Passenger Services Act, or PSA) is a protectionist piece of United States legislation which came into force in 1886 relating to cabotage. Essentially, it says:
No foreign vessels shall transport passengers between ports or places in the United States, either directly or by way of a foreign port, under a penalty of $200 (now $300) for each passenger so transported and landed.
As a result, all vessels engaged in the coastwise trade have been required to be coastwise-qualified (i.e., U.S.-built, owned and documented). Under the Passenger Vessel Services Act of 1886 (46 U.S.C. § 55103), non-coastwise-qualified vessels cannot transport passengers directly between U.S. ports. Generally, a passenger is any person carried on a vessel who is not directly and substantially connected with the operation of such vessel, her navigation, ownership, or business. The precise definition of what constitutes a U.S. port ("coastwise point") includes artificial islands and similar structures, as well as to mobile oil drilling rigs, drilling platforms, and other devices attached to the seabed of the Outer Continental Shelf for the purpose of resource exploration operations, and the anchored warehouse vessels that supply drilling platforms.
The handful of U.S.-flagged cruise ships in operation are registered in the U.S. to permit cruises between the Hawaiian Islands, or from the continental U.S. to Hawaii.
The Passenger Vessel Services Act, however,
In accordance with this law, cruise lines that operate foreign-flagged vessels are fined $300 for each passenger who boarded such a vessel in one U.S. port and left the vessel at another port. The cruise lines typically pass this cost on the passengers who "jump the ship". Exemptions are available in the case of family emergencies etc.
Some exceptions have been made to the requirement of the Passenger Services Act. For example, Canadian vessels may transport passengers between Rochester, New York and Alexandria Bay, New York until such time as a U.S. carrier enters the market (46 U.S.C. § 55121(a)), and between ports in southeastern Alaska (46 U.S.C. § 55121(b)).
