Crew
Overboard

On
Saturday 23 Oct. 2004, Uncensored a 36 foot racing sloop was competing
in the first BYC pennant race. A lifeline fitting failed and four
crew fell overboard.
In the interest of safety I would like to offer fellow yachtsman
an insight of what happened, what we did, what we should have done
and what we learnt from the experience.
The
fitting that failed was a shackle. Instead of using the type that
uses a threaded pin, I had used one with a clevis pin with a circular
split ring arrangement. This is attached to the push-pit and forms
the 'bitter end' for the lashings that are attached to tension the
lifelines. The boat was fine-reaching on port tack and the crew
were hiked out on the port side and leaning against the lower lifeline.
When the shackle failed the lower lifeline instantly lost tension
and the crew literally fell overboard.
The
first response for me was to "crash- tack" the boat. This
reduced the speed immediately. The need to kill speed was important
as some crew still had hold of some ropes or stanchions but were
being dragged through the water.
As the speed of the boat was around 8 Knots, it was creating a considerable
amount of drag for them. The other advantage of the crash tack was
it made the port side, the leeward side, so the boat was heeling
towards them and the boat was virtually stationary. This made it
a bit easier to drag some of them back on board.
One
of our crew had a Stormy Seas vest on. He decided that the remaining
crew on board were busy enough recovering people close to the boat,
and with the rig back winded and unconventionally loaded and as
it looked a bit worrying, he inflated his vest and moved away from
the situation. As he was communicating with the boat and confirmed
that he was OK we were able to concentrate on getting the remaining
three back on board.
Planet
X and Quetzacoatl, were just behind us and saw our unexpected manoeuvre,
and then noticed our fourth crewman in the water. Both crews should
be congratulated on their quick and decisive response in offering
assistance. By having these boats clearly showing to us (by stopping
and lowering their headsails) that they intended to assist, meant
that we could prioritize getting the crew back on board, and sorting
out the mess with the sails and rig caused by the crash tack before
going after our fourth crew member.
It
appeared to us that Planet X deployed a lifesling, but had difficulty
getting it to our crewman. The life rings in these units are very
light and don't have much weight to overcome their windage when
you are attempting to throw them to a target. I thought that it
was a good idea however clearly had some difficulties. Quetzacoatl
was the next to arrive and they used a different approach. They
steered almost head to wind and managed to back up and recover our
crewman by dragging him over their transom.
Once
we'd recovered three crewmembers and saw that the fourth was safely
on board Quetzacoatl we retired from the race and motored home.
So
what did we learn???
1) The shackle had an adequate rating for the job providing it was
properly orientated. As the fitting was lost in the incident I can
only conclude that the complete shackle rotated so that the loads
were on the sides, and not between the top and the clevis pin. The
body of these types of fittings are pressed stainless steel and
if rotation happened the sides would bow. This would then place
the clevis pin and split ring in a tension, instead of being in
shear. The split ring probably sheared and released the pin and
then remaining part probably straightened and released the lashing.
A shackle with a screw type pin or a quick link would have handled
this loading better.
2) A crash tack in this situation contributed to speedy recovery
of most of the crew. It washed off speed and made the port gunwale
on the leeside, which helped us drag the crew across the deck. We
could have manoeuvred the boat and sailed back but with only half
the crew onboard this would have been slow and increased the distance
between the crew and us. Without knowing if there were any injuries
we were not prepared to separate from the crew.
3) Some time ago we had replaced our lifesling with a throwbag.
I thought that would be easier to deploy to a MOB, but when half
the crew are in the water there simply wasn't anyone available to
do this. If we had our lifesling available I could have deployed
it, leaving it floating away from the stern. This would have left
me available to assist in recovering the others whilst the crewman
in the Stormy Seas vest could have swam to it. He would then have
been attached to the boat and we could have recovered him later.
I'd hate to think about what could have happened should this have
happened on the way to the Pipe Opener.!
4) We have pelican clips on the transom lifelines. The lower one's
captive ring was too tight to be unscrewed with wet hands. This
made the stern recovery for one of our crew particularly uncomfortable,
as he had to be dragged over the middle line. The functionality
of these types of clips should be checked regularly.
5) Lifeslings are not the total solution. They have their own unique
problems.
The floating line tends top get tangled when it is stored in its
bag making them difficult to deploy. I think it would be prudent
to check this regularly.
I'm
hoping that this article makes you think about what you would do
in this situation. My advice is to have a plan in your mind for
crew recovery but be prepared to modify it. Think about how would
you get people back on board. A closed transom might be more difficult
than an open one. A cruiser might have a lot more freeboard.
*
What equipment do you need to get people back from the side?
* Do you have adequate equipment handy to deal with a crew overboard
situation?
* Does every one know how to activate the MOB on your GPS?
* Do you use a lifesling or ring?
* Have you ever tried to deploy any of this equipment?
* Is it in good condition?
* If you were overboard and injured what would you do?
* If you have an inflatable PFD maybe you should wear it. Its no
use to you stored in your sailbag and no-one would want the job
of returning it to your next of kin.
