[C38] boom brake?

Thu May 24 00:22:13 EDT 2012

I made a boom preventer based on a Don Casey design,  I put a bail on
the aft end of the boom (Very Important to attach to the end of the boom
not the middle) attached to it a spliced dynema line that is about 7
feet long, it stores along the boom when not used,  then a large block
with webbing attached that attaches to the bow cleat, a line runs
through it attaches to the dynema line outside of the spreaders, the
tail of the line it is cleated near the cockpit.   To jibe undo the
cleat, jibe, walk up to the boom unattach, walk it around the mast,
outside the spreaders reattach then tighten the line and cleat.   Make
sure what ever you do is at the end of the boom, if the boom should go
in the water when attached at mid point that is where the load will
transfer and bend your boom.

Hello all

Sailing in San Francisco Bay can be daunting for beginners. I sometimes
let them have the wheel to allay their fears which in some instances has
resulted in accidental jibes when my attention was elsewhere. I've had
to re-rivet some hardware on the boom and I think the gooseneck crack
which I had to get welded may have been the result of one of those
instances.

Trying to be cheap, I went to a climbing store (REI) and got a belaying
device and some rope and tried to rig something up. The results were
unsatisfactory so I went back to rigging preventers as needed.

The Wichard Gybe-easy seems like a good compromise between inattention
and focus. Does anyone else have experience with this device?

Cheers

Pierre: I wonder if, given concern for bucks, you would use that pricey
boom brake much on a C38? If you plan to do a lot of tacking down wind,
ok, but then you have to get back up wind either before or after. You
can get a similar device at a climbing store for less money or use a
line from the boom to the rail as a preventer  (use a trucker's knot for
friction). I often center up the main before jibing.  Others on this
site know much more than moi, and they will have more sophisticated
advice.

Hello All again

Thanks for all the inputs. I'm confident I can pull it off now. I don't
have the budget for the more expensive line but since I have a furling
jib, once it's up, it's up and I'm willing to tweak once in a while.

Doing the math, the I and J dimensions yielded a 102' halyard length. I
definitely won't pass the line to the cockpit since there are no blocks
or cleats (or budget) for that. My next purchase pennies are targeted
for a Wichard Gybe-easy boom brake... Oh yeah - the woodwork is another
topic in itself..

Cheers

Pierre: I agree with other comments on length and Steve on the
electrical tape for feeding through. I would not use Sta set X but
rather a spectra or T 900 type line. Much less stretch. If using one of
these you will have to have the splice professionally done

	Subject: [C38] Replacing jib halyard

	Hello All

	As a test of my "seamanship" I've decided to replace my jib
halyard. I've never done it before and I spent some time reading all of
what was posted regarding halyards on this list since 2005. According to
another web site, the recommended length is 117'.  I want to go with
no-wire Sta-Set X 7/16" which at about $120 appears to be "cheap"
enough. A YouTube I saw showed it's all a matter of butt-splicing the
ends (old to new) together with waxed thread and pulling through.

	Newbie questions:

	1) Is 117' the correct/best length? (jib is mast-cleated)
	2) 7/16" diameter OK?
	3) Sheaves/pulleys OK with all-nylon rope?
	4) YouTube video too optimistic?
	5) Am I going to regret this?

	Thanks for the advice.

	Cheers
