Naturism as selfdefence

This schooner I had purchased with almost the last of my money for f1500. beach freedom led to another and having little work but plenty of time myself and some friends sailed Gloria across the Atlantic. We had many experiences, not least was the oil pressure on the engine going AWOL. But finally we did fetch up in St Lucia. There my lady friend Helen rejoined us and among the crew left.
Our next stop was the isle of Bequia, the pilot publication warned that the holding for the anchor in the primary bay wasn't so great and to be mindful of yachts dragging their anchors. Yet we didn't hit anything and came to rest in a fairly sheltered area. Myself and friend Edmund donned snorkels and masks and dived to check said anchor, it was not dug in very well at all, so I stacked some stone on it. Subsequently after surfacing we place another anchor out to make sure. beach freedom was that the sea bed wasn't too deep sand over coral, and also the anchor was having trouble biting.
A couple of nights later during another squall I had my slumber disturbed by the unmistakable sound of double diesels going hard astern, on issuing from my bunk and running topsides I saw a big catamaran very close to our bow taking evasive action. He'd clearly pulled his anchor and only managed to miss us and retrieve his equipment before going off to try again somewhere else.
This scenario was rein acted several times over our stay in the various Islands. beach bum didn't pull, with no engine we could not afford to, so we put down tons of chain and an additional anchor at every stop. Nonetheless, after we got hit by two yachts one night in the same time, I resolved to find a solution to this issue. You dear fellow naturists will enjoy the answer I found to this problem.
The group of yacht uses we'd most trouble with were the ones who charter their yachts, many of these people haven't had plenty of expertise in Anchoring, and there is rather a lot of technology to what on the surface seems a simple manoeuvre. These folks, tend not to have spent substantial quantity of time in close proximity to other people as in a tiny yacht surroundings. These people are the sort that haven't come face to face with bare human bodies except in some specific scenarios. In fact I discovered that if I appeared nude in the cockpit while I read a novel and waved to the newly arriving charter yachts of an evening, they would go right over to the other side of the bay, "hey presto" problem sorted!)
