The types of yachts that are being sunk are not owned by billionaires, or even millionaires.

These are small boats under 20 meters, most of those attacked are liveaboards and it's a result of over-fishing along the Portuguese coast all the way up to the bay of Biscay.

Ask yourself, why is it that after centuries of sailing in this region, is it only in the last few years these attacks have started to happen? (This is the common suspected reason)
