If that is the rule, than yes. Indeed the captain has that authority. Luckily you have the option to dive on another vessel.

You don't need to make it sound sinister. No threats are ever made. Like any vessel, I have rules which are made clear prior to boarding. Passengers may accept or reject them. Once aboard and underway, they are under the authority of the Captain.... like it or not.
