Okay here’s my question. Does it help to have the jib twist be adjustable on a CR-914? what I mean by that is if I could move the jib boom fore and aft a tiny bit, or make adjustments to the jib booms position fore and aft, would I gain any advantage? There would be more twist I think if the boom went aft etc, know what I mean? I’ve found that the back stay tension has no effect on jib twist. It’s a separate issue from jib slot which I can already adjust. I’ve noticed big changes in boat speed with small changes in jib slot but I was wondering if jib twist is a factor as well in how the main and jib inter-act aerodynamically?
