I ask because the kind of cold water we
experience year-round here in the Pacific Northwest has to be taken into
consideration when you choose a type of lifejacket.
Many people find it almost impossible to swim in
the normal position, that is, face downward, when they’re wearing a lifejacket.
This is especially so when you’re wearing an inflatable device that provides
maximum flotation, but at the expense of turning you into the Michelin Man. It
is usually possible to swim on your back by flailing your arms a bit but it isn’t
easy and you won’t get anywhere fast, especially if you’re trying to make way
against a stiff wind. You’ll also find it very difficult to board a boat while
wearing an inflated lifejacket.
The point to take note of here is that experts
claim most people who fall into our waters have only 10 minutes to swim
anywhere in any case. After that, the cold starts affecting you so that you mostly
lose control of your fingers, arms and legs.
Inflatable and other lifejackets are designed
to roll you face-upward and keep your head clear of waves so you can breathe
even if you’re unconscious. They weren’t designed for ease of swimming — just
to keep you afloat until rescue comes.
There are buoyancy aids shaped like vests, and
lacking collars, that offer you more freedom of movement for swimming. But if
you choose one of these you should be aware that if the boom hits you on the
head and sends you overboard unconscious, a so-called buoyancy aid won’t turn
you onto your back and it won’t have as much flotation as a full-blown
lifejacket.
If you are conscious, and a reasonably good
swimmer, you can partially deflate an inflated lifejacket so that you can turn
onto your stomach and use your arms to swim, after a fashion, which you might
want to do if you are very close to shore or your yacht. And I mean very close,
certainly within 50 yards. You can always inflate the bladders by mouth if you
run out of steam and need to rest on your back. If you’re farther away from
safety, you should await rescue and conserve heat and energy by curling in a
tight ball.
Cold water of the kind we sail in, usually
about 45 or 50 degrees Fahrenheit, is a sure killer, so it’s important to give a
lot of thought to the kind of boating you do and the best kind of lifejacket to
go with it.
Float coats make a lot of sense when it comes
to conserving body heat in and out of the water, but they’re expensive and not
ideal to swim in. The best defense against drowning or hypothermia is not to
fall overboard in the first place, which calls for harnesses and tethers, but
even sailors who have them don’t always wear them. What’s not always
appreciated is that people also fall overboard in calm weather when there doesn’t
seem to be any threat, or any need for a lifejacket. If the water’s cold, there
definitely is a threat, a constant threat.
So give it some thought and decide what kind
of lifejacket is best for the kind of boating you do. And if you need some
facts and figures to help you, and maybe frighten you into action, here’s a
very good website to visit:

I agree
ReplyDeletenot sure about the self inflators anymore - especially as I sail alone
