Interesting. But unless it’s the Arizona or some other inshore, Navy protected vessel, or one so deep as to make it unpractical the odds are it will eventually be plundered. Time will make the offense less. Like the 17th Century hulks systematically searched for dubloons in the Caribbean and Florida coastal waters.
The offending vessels have to be somewhat specialized, and should be simple to track from orbit. They need to be sunk and the survivors left for the sharks.
