PUP: Flopper Stopper

Ahh, one of my favorite topics.

I LOVE, LOVE, LOVE my Flopper Stopper.  Marian and I got to the point where
we could drop the hook and have the flopper stopper deployed in less than 5
minutes.  On the west coast of Mexico and Central America there are a dozen
or so  anchorages we used where we tucked in behind a bight where we were
exposed to swells refracting off the beach or wrapping around the rocks.
The first time we did this was the first time I'd ever deployed my Flopper
stopper.  I kind of knew what to do, but honestly had never even gone
through the motions of hooking up the lines, it looked so simple I figured
I'd learn it "just in time".

Well we get anchored and the boat starts rolling.  I watch Patrick and Susan
on Paloma deploying theirs and figure this is the time.  We rig the pole and
throw the plate in the water and walla, roll is reduced at least 80%.
However, the pole goes, squeak, bang bang, squeak, bang, bang, (well not
really a bang, kind of a knock).  Anyway we figure we are lucky to have the
hook down and to be around the cape we were crossing.  So we go off to
sleep.  About 1:00am the squeak, bang bang really has turned into Bang Bang,
so I get up and go to the Pilothouse and turn on the deck lights to watch
the pole under motion.  What I see is that Patrick has rigged his pole to
be about 45 degrees above horizontal, while mine is horizontal to the
horizon.  I figured the farther you get the pole away from the boat the more
stabilizing moment is available.  Well I pulled out the laminated sheet that
describes how to deploy it and sure enough it says, raise the pole to 45
degrees.  Then I realize why.  When the boat rolls away from the pole it
goes under stress and pulls the plate up through the water, when the boat
rolls back into the plate the strain on the plate goes to zero and the
stored energy in the halyard pulls the wisker pole up, essentially making
the line go slack.  When it comes back under tension, bang bang.  So I
realize having it up 45 degrees improves the down force on the for and aft
guide, eliminating (or dramatically reducing) the bang bang.  Well I now
have to decide how to fix it.  The last thing I wanted to do was pull it in
at night, so I figured I'd just go up on the boat deck and pull in some
slack as the boat rolled into the plate.

Marian and I had adopted a rule when we left.  We agreed that no one would
go outside the pilothouse (or Portuguese bridge) without the other being
awake and at the helm.  Here I was at 1:30am trying to decide if I should
brake that rule and go on the boat deck without waking her up, or simply ask
her to come up and sit in the pilot house while I went up.  Oh, it was
blowing just a bit, not calm.  Well I decided if I started breaking our
rules within the first week of the trip we were going to have a hard time
making any new rules so I went down and woke her up, asking her to sit in
the pilothouse and make sure if I fell in she threw me a line.  I put on a
life jacket and went up to the boat deck and raised the pole to 45 degrees
and walla, problem solved.  We both went to sleep and had a great nights
rest.

As far as making it easy to use, our is really simple, much easier than on a
N43 or a 55 because the plate is smaller and the rigging is really light and
easy to handle.  We deploy the pole, just a halyard, for and aft stay and
attach the plate to the hanging line.  I open the cockpit door and toss it
in the water.  To retrieve I deploy a boat pole and hook the downline.  I
pull it back to the opening in the cockpit door and lift the plate up out of
the water into the boat.  I never had a situation where the boat rolled so
hard I couldn't hold onto the plate.  I did ask Marian to take the boat hook
from me as I pulled it in, until I learned to collapse the pole as I
retrieved the line, then I didn't need any help at all.

In summary, the flopper stopper on our boat was fantastic.  I can't imagine
being at anchor in a rough or rolly anchorage without it.
