I do believe in karma. Do unto others...... Primadana had it coming. I have no sympathy for them. I doubt France will want them back either. I bet a Bahamian jail isn't much fun.
However, I could not imagine climbing aboard a boat and taking things, whether I knew the salvage rules or not. The crew of Fata Morgana are thieves. No matter how remote, I would be wondering if her crew was about to return with a tow vessel any minute.
I will give them this much faint credit. I doubt they mentally processed what they were doing was wrong. Could make them incredibly naive, with low moral values, or the worst of criminals. I'm guessing the former.
Frankly, this event somewhat validates the old saw "What goes around, comes around" so I have no sympathy for the interred yacht owners what-so-ever.
As to the "wreckers", wrecking is an old, long practiced tradition in the Bahamas, extending back to the 1650's at least. Entire communities developed and survived, if not thrived, on the practice. Coming upon what was pretty clearly an abandoned wreck it would not be unreasonable to assume that one might take something of value. It is not something I might be inclined to do, but...considering the openness with which the crew of Fata Morgan related the event, there was clearly no criminal intent.
Similarly, if one were to come upon the long abandoned Swan Wolfhound at sea and go aboard and take some of the gear, would that be criminal? Would it be later if the abandoned yacht fetched up on some shore (as it may sooner or later)? I don't think so.
So I would not be too quick to make judgements, eh?
