The Lights Go On
The Lights Go On
Not all light-air situations are created equal. Learning what separates one from another, and that each requires a unique approach, is the first step to success. From our July/Aug 2011 issue.
ROB: I’ve always wanted to talk to you about this light-air sailing thing. I’ve read all the books …
Doc: … as you often point out …
ROB: … but I just don’t get why some of the authors say you should have full sails in light air, and some say you should have flat sails. How does that work? Surely there’s another way to think about this.
Doc: It can be confusing. How have you been going in the light stuff?
ROB: Actually, we’re quite fast when it’s soft.
Doc: What’s your best thinking on how to set up for those conditions?
ROB: That’s what I’m asking you! I’m getting quite confused.
Doc: Can you think of the last light-air race when you were really fast?
ROB: Yes, two weeks ago in the twilight race. We had Joe sitting in the middle of the boat, and Sue and I were up on the rail. We smoked ‘em up the first beat.
Doc: … and how were you set up?
ROB: Well, the main was quite deep, and I was sheeting it so that the top leech telltale was just flicking—about 50 percent flow. The jib cars were forward, and the leech telltale was streaming, but I was continually telling Joe to sheet on just a little more. He kept giving me this dark look and not really changing anything!
Doc: So you were sailing in “squeeze” conditions. There was enough breeze for you to focus on getting as much power as possible out of what was there, without worrying too much about stalling the rig.
ROB: That’s exactly how it was. I was trying to extract as much power as I could, going right up to edge of stalling the sails, but not quite overdoing it, and—hang on, I think you’re saying there are other kinds of light winds? This feels like one of those infomercials, and here comes the “but wait, there’s more” pitch.
Doc: Bingo! I think that single idea, that there are multiple kinds of light air, might be a key to upwind speed in the light. It boils down to the fact that, through the range of breezes we lump under the label “light air,” you make the biggest changes in your rig settings compared to any other conditions. We don’t really notice the big range because we usually only start races in the top of that “light air” band, that is, races usually don’t start unless there’s a reasonably stable breeze of at least 5 knots. But we often end up racing in some real drifters.
