[The PVSA] force[s] cruise ships going from one US city to another to either stop at what is called a “far foreign port” (ie., outside of North America), or to stop at a foreign port within North America before returning to the American port of embarkation. Thus, a cruise ship cannot start in Los Angeles and end in San Francisco unless it stops in Tokyo or Lima first. But it can start in Los Angeles, go to San Francisco, then later end in Los Angeles, as long as it stops in Ensenada, Mexico or Victoria, British Columbia first.
