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 Second Wind

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.
