HOW SAFE IS THE OCEAN for small
yachts these days? Satellites looking for possible debris from Malaysian
Airlines Flight 370 keep sending back pictures of scores of large objects
floating around in the lonely Roaring Forties. So far, none of these objects
appears to have come from the missing jetliner, though. It’s just random
flotsam that makes you wonder what would happen if you ran into it in heavy
seas on a dark night in a small yacht.
It is not easy to estimate how much
of a threat this represents for the thousands of cruising sailboats currently
working their way around the world. Much of this flotsam is too small to do
much damage to a reasonably sturdy boat but unfortunately some of it actually
is substantial enough to punch a hole through a wooden or fiberglass hull.
What we do know, however, is that
energy equals mass multiplied by the square of the speed it’s traveling at. In
other words, if you hit a large piece of debris at 3 knots, it will do x amount
of damage to your boat. If you hit it at 6 knots, though, it will not do twice
as much damage (2x); it will do four times as much damage (4x).
This makes a good argument for slow
sailing boats, especially at night, because there is normally no hope
whatsoever of spotting a dangerous piece of low-lying debris ahead of you on a
dark night in the middle of the ocean. It also makes a good argument for
something that cautious sailors used to do in the early days of yacht
circumnavigations in the last century: tucking in a reef or two at nightfall to
reduce speed and perhaps avoiding the need to flounder around trying to reef
the sails in a sudden wind squall at 3 a.m.
There is already plenty of stuff in
the water for a sailboat to hit without the airlines adding to the problem.
Ivor Wilkins, a journalist living in New Zealand, ran into a whale one night in
his yacht Thistledown. Author Frank Wightman ran into a tree off the
mouth of the Amazon in his sloop Wylo
one dark night. And Lord knows how many people have run into semi-submerged
steel containers. We know hundreds of containers fall off ships every year, and
no small yacht is a match for one of those.
I don’t know of any modern skippers
who insist on shortening sail at nightfall. There may be some, but I don’t
think there are many. But perhaps there will be a few more now that the
satellite searches we’re seeing on television every day make it obvious that
charging through the dark seas at high speed at night is the equivalent of
driving down the freeway while wearing a blindfold.
