Naturism as self defence

In nudist was sailing a very beaten up schooner called "Gloria" around the Caribbean isles which make up the Grenadines. This schooner I'd purchased with practically the last of my cash for f1500. 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 island of Bequia, the pilot book warned that the holding for the anchor in the primary bay was not too good and to be careful of yachts pulling their anchors. We came in during a gale power squall, complete with horizontal rain (warm), without an engine the manoeuvre was a trifle challenging. Yet nudism did not hit anything and came to rest in a reasonably sheltered spot. Myself and buddy Edmund donned snorkels and masks and dived to assess said anchor, it was not dug in very well at all, so I stacked some rocks on it. Subsequently after surfacing we set another anchor out to make sure. The issue was that the sea bed was not so deep sand over coral, and also the anchor was having trouble biting.
A couple of nights later during another squall I 'd my slumber disturbed by the unmistakable sound of double diesels going hard astern, on emerging from my berth and running topsides I saw a sizable catamaran very close to our bow taking evasive action. He'd clearly pulled his anchor and only managed to miss us and recover his equipment before going off to try again someplace else.
This scenario was rein acted many times over our stay in the many Isles. nudism didn't drag, with no engine we couldn't afford to, so we put down lots of chain and an added anchor at every stop. However, after we got hit by two yachts one night in the exact same time, I concluded to find a solution to this issue. You dear fellow naturist s will like the solution I found to this issue.
The group of yacht uses we'd most trouble with were the ones who charter their yachts, many of these individuals never have had lots of experience in Anchoring, and there is quite plenty of technology to what on the surface seems a easy manoeuvre. These individuals, tend not to have spent large quantity of time in close proximity to others as in a tiny yacht environment. These individuals are the sort which haven't come face to face with bare human bodies except in certain situations. In fact I discovered that if I seemed nude in the cockpit while I read a book and waved to the recently arriving charter yachts of an evening, they would go right around to the different side of the bay, "hey presto" issue sorted!)
