The word "yacht" is misleading. It was a 15 meter charter sailboat, of the type Sun Odyssey 519. If you are looking for rich fucks to make fun of, you won't find them on these kind of boats.
The attacks are happening from the Moroccan side of the straits of Gibraltar all the way up to the north of Portugal and the bay of Biscay.
All of the yachts attacked are under 20 metres, not owned by billionaires and a lot of them are liveaboards who have sold everything up to go travelling.
The attacks are thought to be from the result of over fishing along the Portuguese coast as well as incidents between those fishing boats and Orca pods yet it's smaller boats that are being attacked.
