Depends on the crew member
This post sounds like a product of a rather "spirited discussion" with your crew, Gary... ;o) I think that it's important to know what kind of sailor you are before you answer this question. When there's no imminent danger or serious navigational error, I'm a "set and forget" type of sailor- I don't like to make a lot of little adjustments along the way in order to get absolute maximum efficiency. I'd rather sip my margarita and relax, and I'll get there eventually... My wife, on the other hand, is an up-and-coming racer-She wants to squeeze every bit of forward motion out of the sails that she can, all the time.If it's my spouse at the helm (who is VERY interested in learning to sail better), I'll suggest a change and explain why (although she is getting to be a better sail trimmer than I am!). She will usually try to discuss the physics, math, logic, and textbook reasons behind why she's got it the way she does, but sometimes she forgets to watch the big picture. She doesn't react well to me making adjustments when she's at the helm (unless I am assigned to do so), but neither one of us learns anything if I just keep my yap shut. (There have also been times when she's right...) If it's a sailing-knowledgable friend, I'll usually just keep my mouth shut, except maybe "come port/starboard a bit..." This generally doesn't hurt anyone's feelings, and is quite effective. If it's someone who isn't really interested in learning how to sail, I'll usually just make the adjustment myself. If they ask why, I try to explain it in simple terms, and this seems to keep them satisfied- They're usually still in wonder about the way the boat moves, and slightly overwhelmed by all the things that need to be kept track of- and amazed that any one person (read:you) can do it at all.Good luck with crew relations,--Jon BastienH23 '2 Sheets to the Wind'H25 'Adagio'
