A documented vessel transporting cargo that transports not more than 12 individuals in addition to the crew on international voyages, or not more than 16 individuals in addition to the crew on other voyages, is not subject to inspection as a passenger vessel or a small passenger vessel if the vessel is otherwise subject to inspection under this chapter.

Except when subsection (e) of this section applies, before an individual in addition to the crew is transported on a vessel as permitted by this section, the owner, charterer, managing operator, agent, master, or individual in charge of the vessel first shall notify the individual of the presence on board of dangerous articles as defined by law, and of other conditions or circumstances that would constitute a risk of safety to the individual on board.

A privilege authorized by this section applies to a vessel of a foreign country that affords a similar privilege to vessels of the United States in trades not restricted to vessels under its own flag.

A fishing, fish processing, or fish tender vessel that transports not more than 12 individuals employed in the fishing industry in addition to the crew is not subject to inspection as a passenger or small passenger vessel.
