Hello from steamy Miami. I'm
planning on having the option of running the main halyard to the cockpit
(when needed...mainly when I solo with my five year old) for safety
reasons, i.e. to be able to release it quickly. I seem to recall photos
from the old website re running the halyard thru some blocks and a stopper.
Where can I find those photos? Also, how does one remove the liner from the
cabin when putting in new hardware on top of the cabin?
Also, I'm having a heck of a time rolling in my screecher, even after
making adjustments per discussions with Will. One local rigger is
suggesting putting a two-part pulley system between the top of the
screecher and the mast with the idea of tensioning the screecher wire to
the proper angle. The rigger states that in addition to obviously making
the tensioning of the screecher halyard easier it will also take
significant pressure off of the halyard as it enters the mast thereby
somewhat mitigating one of the primary break points. Comments?
Thanks...Tropical

Phil—
You're probably thinking of the photos I posted...since I have the halyards
led aft on my boat. You can see photos and read more about it at my blog.

What sort of problems are you having with rolling in the screecher?
If it takes a lot of force to do it, especially in higher wind, you should
fall off and blanket the screecher with the main. In 15 knots of wind I
find it almost impossible to do it also, and have to blanket the sail. I do
the same thing with the genoa as well, especially if I want it to roll up
as tight as possible. Heading into the wind with either sail won't work as
well either. I try to blanket both sails almost all of the time to get the
roll as tight and smooth as possible.
If it doesn't roll in all of the way, then it's probably the number of
turns you have on the drum. There should be maybe 4 turns left on the drum
when the sail is furled.
If the furling line tends to gather at the top or bottom of the drum and
occasionally jams, then the angle of the line as it approaches the drum may
not be close to 90 degrees. It's got to roll up smoothly on the drum, and
that means that you should also leave some pressure on the sheet(s) as you
do it, and on the furling line when you pull a sheet to let it out. This
goes for the genoa as well. You may have to move turning blocks around to
get the 90 degrees. The screecher furling line also had to go thru the eye
that's mounted perhaps 5 inches from the large bail on the bow sprit.
The screecher halyard has to be reasonably tight, and that means that you
will have to use the winch to do it. But don't grind that hard - I try to
tighten it to the point where the head stay (and genoa) start to sag just a
little, then back off maybe 2 - 3 inches. Installing a pair of Lewmar
clutches (same as on the ama and trampoline control lines) on the mast will
help here. Many of us have done this already.
The wire luff on the screecher also has to be pre-loaded with maybe 3 turns
before you attach the pendent to the drum, but that will effect rolling out
the sail more than not getting it back in. There could be too many turns
though.
I've never had even a slight problem with the screecher. It rolls out
easily all of the way, and I can get it back in with litle effort or drama.

Thanks Dan and Ron for the
responses...
Dan, nice setup per your blog...how did you remove the interior liner to
put in the clutches?
Ron, sorry if I didn't explain it well before, but I'm having a very hard
time rolling in the screacher (it rolls out easily) even when blanketed by
the main. I've led the screacher halyard back to the self-tailing winch
just to play with different tensions, and the only tension that seems to
work is very tight...then the sreacher rolls in easily. That's why the
local rigger is suggesting the two-part purchase system as noted in my
previous post. FYI: Will suggests bringing in the sprit half-way, then
tensioning the screacher halyard as much as possible by hand, then pulling
at the sprit as much as possible by hand with the pulley in the anchor
locker, and playing with the backstay to see if it needs more
tension...this does not work on my boat (does not help rolling in the
screacher), plus it leaves me with a 4-foot sprit that's only extended
about three feet. I'd like to get the screacher working since it's so much
fun to sail with (particularly in our light summer winds here) and works
well from 60 degrees to a deep reach.
I have some other questions but I'll try to post them in the proper
categories...Philip (Tropical)
Thanks...Philip

In theory, we have the same boat with the same Behrig sail, sprit, mast,
furling setup, etc. Mine is easy to roll out or roll in (as long as you
fall off and blanket the sail when the wind picks up). Something has to be
different (or wrong) on yours. Is the top swivel not rotating when you pull
on the furling line? Maybe aim a pair of binnoculars up there the next time
you pull it in?
I would re-check everything I mentioned above before I went to installing
another line at the top of the mast to tension the top of the sail. You
don't really need that. There's got to be 30 or more 28's running around
without it.

I cut through the cloth liner. I am working on replacing the cloth liner
with one made up of 1.5 mm or 3 mm marine plywood instead. This would allow
me to insulate above the overhead, as well as put in proper access panels
to get to deck mounted hardware. It also will give me more options with
mounting things like cabin lights and running wire. That’s going to be my
primary project for this winter.

I went out today and the winds were light so i decided it was time to work
out the bugs with the screecher again. It came down to the swivel not
rotating under load. The sail did not unfurl so I slacked the halyard a bit
and noticed that when the sail unrolled the swivel did too! I brought the
swivel home to work on it.

I sent the swivel back to
Schaefer marine to have it checked out. I found out that the Schaefer
system comes with a five year warranty. A very helpful Carol hand carried
my swivel to the GM there and after a quick check out they are going to
send me a new unit. Nice company that stands behind their products. After I
get it installed I will let you know if it fixes the screecher problem.

The upper swivel has ball bearings as I recall. It should turn VERY easily.
Not sure how your unit could have failed. It's a very simple design.

That is what I thought too. When
the swivel is in hand it spins freely but locks up under load. This could be
all my screecher problems.

Do you think that you could be tensioning the screecher too much? I know
that too low and too high will both cause problems. I recall that you've
busted mast cleats tightening it, but that could have been caused by the
direction of pull. I go hand tight then maybe 1/4 turn on the winch
(without using the cleat as a turning block), then backoff just a little to
get the head stay to straight out. A slight sag in the rolled up genoa would
mean that the stay is no longer doing it's intended job, and you'd have too
much pressure on the screecher upper swivel. I'd be carefull with the back
stay as well - excess force there could transfer to the screecher halyard
too.

Ron,
I do it the same way. On the same note, when I spotted the swivel not
spinning while I was letting out the sail I had already slacked the halyard
a bit. I have had to do this in the past to be able to unfurl the sail.
The good thing is that the new swivel is in the mail and I should get here
in time for Saturday's race.

That did it,
The swivel came in Friday in time for the race. When I used the sail it
unfurled perfectly.
