Cal 34 pointing ability
kvcpls2008-06-04 14:37
We replaced the standing rigging on Second Wind last year. Since then
we have not been able to get her to point very well. We've "tuned" the
rig according to "the book" as best we can and everything seems to be
about right. The mast is true side-to-side, we have about 1' of rake
(acually a little bit more) in the mast. There is a VERY slight fore-
aft bow at the spreaders. The shrouds "feel" about right (if there is
such a thing). In a stiff breeze the lee lowers are just tight - on
the verge of slacking. In a stiff breeze I am able to get everything
trimmed so the helm is neutral. The one thing I'm not sure about is
the forestay. Under these conditions how much sag should there be in
the forestay? I'm seeing (maybe) 6 to 8 inches. My gut tells me this
is too much. Everything I've read says too much sag will kill your
pointing ability. I've tried adding tension to the backstay but I'm
affraid I'll pull the boat apart if I add too much.
Any suggestions?

Keith, it depends on sail cut and material, but on the 25 we take out
(ease) all the backstay upwind and it improves pointing. Also, some
scalloping in the jib luff helps. If you have a trial horse out there,
do just the opposite of what you've been doing with the backstay and see
what happens. My observations are all empirical from experience. No
book to quote. However, I do have a few theories on why it works.
How does the helm feel in light air? Is it negative? If so, Move the
masthead forward.
Cheers
Charlie
