I think this kind of thing is getting quite common, see a few warnings appearing on boat/fishing forums I look at. The remote location is important. I will see if I can find one about a boat allegedly in Wick, the scam was the seller would meet somewhere and get some money for goodwill through Western Union or similar. There was a bit of communication about the boat for sale and the "buyer" put it on the forum. There is a website that does windups of these guys, can't recall it offhand.
