Caribbean Pirates: "Fishermen in fear"

From Eagle Speak : A story linking boat engine theft to drug smugglers.

I overheard a conversation today from someone with a bit of experience cruising in the Caribbean. He mentioned only locking up his boat 'a couple of times' while cruising, as he maintained it was very safe. Yet, in the next sentence, he mentions dinghy theft as being so prevalent that he chained his up at all times. to me, it seems contradictory to leave your 'home' (and your valuables - self included)unsecured, but locking up the dinghy, which could be reasonably replaced. I suppose it all depends on your point of view, but I would protect all my valuables - including those in my home.
