Just a few, Fred...
Fred, my impression is that our cruising styles are usually pretty similar; docks are normally strangers to us, as well. But in small island nations, as you should remember, facilities are few and its very common for small commercial vessels (lighters, ferries, coastal patrol boats, etc.) to share the local waters with the yachties.But to your question: Here are just a few examples that pop to mind, all of which we've visited in the last 4 years, where I would not use a watermaker if I had one:1. Chaguaramas Bay - perhaps the most anticipated of E Caribbean yachtie destinations but colocated with commercial and govt'l vessels; besides that, I'll just bet if you were here you were at a dock (the anchorage is small, deep, overcrowded, has poor holding and enjoys lots of afternoon T/S's) and, because you were at a dock, you had water from a spigot. (We surely did...)2. Let me give you a different combination: Luperon, DR; Charlotte Amalie, St. Thomas; St. Martin (either inside Simpson or outside on the French side); Anse Mitan (gosh, I've forgotten how to spell that) or Fort de France on Martinque; Porlamar, VZ, Port Antonio, Ocho Rios and Montego Bay, all in Jamaica; Isla Mujeres, MX; Horta on Faial, Azores; Falmouth, Cornwall, England and I really could go on (The Yealm, Portsmouth, Plymouth, etc.) - not because watermakers were never used in these places but because they were either overpopulated with cruising boats, enjoyed limited tidal flushing, offered water in abundance from other sources or were near commercial docks...or a combination of the above. In G'town, Grand Cayman, the cruise ships (5 on occasion) were anchored 100 yds behind the yacht moorings (we couldn't legally anchor there), while the lighters full of tourists (all diesel powered; no cruise ship dock) zipped back & forth all day long. Perhaps I'm being overly conservative; perhaps the folks I know who chose not to run their watermakers in these very same places were conservative, too. But hey, it's "my" watermaker, so I get to use my low tolerance for petroleum contaminants.<g>The dirty commercial harbor in T&C is right around the corner from the popular Sapodillo Bay anchorage...but that's a different issue. I mentioned the T&C Is. as an example where cisterns are mandated by building code. The same is true on St. Johns (and I'm guessing parts of St. Thomas, as well). I think this is a common Caribbean notion, as otherwise the strapped island govts. need to install infrastructure they can not afford nor maintain. My point is that cisterns are hardly 'history', in my experience. In Bermuda, an islander wanted me to see her cistern because her roof was built 200 years ago of slate taken from a Bermudan quarry and still worked so well. ("Better than the new roofs, don't you know", she said with a smile). Bermuda is a First World country, and even they still rely on cisterns to the extent they can.Fred, I'm not picking a fight. You're not only welcome to your watermaker, but you have my congratulations for finding something so satisfying and adding so much to your cruising. Each of us have some of those things aboard our boats, and that's a good thing. The fact you don't know about the many boats not equipped with watermakers is your issue; it's not mine. And to take this back where it began, 'systems' seem to be where it's at these days while, at least in my experience, the joy and adventure we get from sailing usually comes from other things.JackP.S. Ile a Vache, Haiti was safer than any other place we visited in the Caribbean, bar none. Hard to believe (until you look at a chart) but true; 10,000 Haitians who were as scared as you or I to visit the mainland.
