Beyond the fact that this sub may be or may not be used by smugglers, is that how do you stop a sub in coastal waters underway in less than 200 FT, to me nobody is able to stop it or to enforce it, the torpedo response would be unfortunate, without communication like in air control , it just might blows up a wealthy folk in his personnal sub for sightseeing tour.
