Ok so had a weird flash back of a film i watched looong ago. i think its 70’s or 80s so pretty old.

it was about these two divers who were looking for gold in old shipwrecks.

After coming to the surface they find that their boat has a group of pirates on board. Modern ones.

i remember a scene where on of the divers has a gold coin in his shirt pocket and one of the pirates takes it from him.

Another scene where the divers find some old bikini and the pirates joke about trying to get the youngest guy to put it on but he refuses and gets beaten by the leader with a belt…yeah pretty odd

eventually they’re all on some island and its a bit chaotic.. can’t remember much after that.

Thanks!
