Anyone else hearing the A-Team music in their head?
Anyway, I have no experience with the cult thing, but I do know that those salvage laws do still apply, at least in Antigua. My uncle used to be an on-call member of a salvage team that competed with a couple of others. But I think there are a fair number of rules in place about who's allowed to salvage ships, about what can be claimed, and under what circumstances any of this can happen. I would imagine that the idea of attacking a ship to then "salvage" it isn't a new one. I'm sure it's been done before, and no doubt sometimes successfully, but I can't imagine there not being certain rules in place to try and prevent that. Also, bear in mind that the bigger the prize, the more rules will be invented by anyone in a position to benefit from not rocking the boat, no pun intended.
