Deceived by salt sea mist

’TIS THE EQUINOX, the season of mists and mellow fruitfulness around here. I’m all in favor of the fruitful mellowness, but I’m not so keen on the mists.

I recall vividly my first serious encounter with mist at sea in the place where I would least have expected it, in the Windward Islands of the sunny Caribbean.

In 1987, my wife June and I had come angling up the South Atlantic on a 31-foot sloop called Freelance, with our then-17-year-old son Kevin as crew. We were 16 days out from the tiny island of Fernando de Noronha, 200 miles off Brazil, aiming for our carefully chosen landfall on the island of St. Vincent, whose Richmond Peak, with an elevation of 3,524 feet, is allegedly visible for 30 miles.

A noon sextant sight put us within 12 miles of St. Vincent, but my eyes told me that we patently weren’t. It was a fine, clear day, and there was nothing on the horizon in any direction. We held our course and sailed on, greatly puzzled.

An hour later, with six miles to go, there was still nothing to see. We had a nervous lunch while we decided what to do. Plainly, we were lost at sea. With my stomach in a knot, I checked my calculations. Nothing seemed amiss.

Our minds began to race. We searched for explanations. Could the chart be wrong? Had the volcanic island blown up and disappeared?

We sailed on half-heartedly, worried and perplexed, until just after 2 p.m., when I noticed a bright flash in the sky up on my right. It was a window shining in the sun, a window on a house high up on a mountainside.

The island of St. Vincent suddenly appeared all around us. It enveloped us, and loomed over us, and seemed so frighteningly close, after weeks of open sea with unlimited horizons, that I instinctively jibed the boat all standing to avoid running aground, although we were still three-and-a-half miles away.

It was a heavy salt sea haze that deceived us. It’s the kind of mist that cuts visibility to less than five miles but gives no indication of its presence. When you’re in fog you know it; you can see it and feel it on you. But the salt haze is deceitful. The sky, the sea, and the edges of the earth look perfectly normal, except, perhaps for the faintest suggestion of a missing line where the horizon should be. But that invisible haze can completely hide large mountains and even whole islands.

It’s a subject you don’t read much about in the boating press, but you need experience it only once for it to make a big impression on you.

Today’s Thought
Fear of danger is ten thousand times more terrifying than danger itself, when apparent to the eyes; and we find the burden of anxiety greater, by much, than the evil which we are anxious about.
— Daniel Defoe, Robinson Crusoe

Tailpiece
“How’d the racing go?”
“My dirty bottom is really slowing me down.”
“Yeah, just imagine what it would do to your boat.”

Hi John, just in case nobody has previously mentioned it to you before, I'll go ahead and state that you're a pretty decent writer. Thanks.

Hi Blondie-Dog, that's a pretty decent compliment. Thank you. I shall try to be worthy of it.

A very interesting and informative post. That is a type of haze that I have never seen or have seen been written about before. Well done.

John,
Is S/V Blondie-Dog the "nom de plume" of Ivor Tungin-Cheaque, Chairman of the V.S.F.C.?

Not that he's wrong,I'm concerned he will blow his cover and be expelled from the club ?

Jack, how did you guess? It's one of his many noms-de-plume, or noms-de-guerre, as he likes to put it. He'll be a bit upset when he finds out you've blown his cover, but as the chairman is the only one allowed to praise me, he can't actually be expelled from the club. Not that he'd be missed if he was. He's a bit if a pee-in-the-a sometimes, if truth be told.

Tony: I suspect it happens in fine weather after a storm in which the water gets stirred up a lot. The result, according to the experts, is haze due to the suspension of fine particles of sea salt in the atmosphere, generally caused by the evaporation of sea spray.
