Re: Rear Stay adjuster
Faster.... I always thought on us Mastheads it was also about headstay sag. You sag it out for more power just off wind, bring it up with more wind and when you are beating to windward. It also helps with rake, and also bend to an extent (not much).
I know with my lowers properly set, I can sag out the headstay with little backstay on, and my aft lowers are tight... but as I bring in the backstay, the forward lowers tighten, aft ease off some, and the forestay really starts to twang. halyard that reaches 8-10 inches aft while hanging a bob at start, to 12-14 inches after full on.
As the wind picks up you can really feel a difference in point as you tension up on the backstay... also in light air, or downwind you can feel the power come back as you back off the backstay... its small and you have to look for it, but it does show itself.
