Anybody have experience with these things? Out for a second sail of the season on Chatfield Res south of Denver on a chilly, misty May Day, my companion Mike got me to set up the spinnaker pole to the jib on a run. We were admiring how well it worked in the 4 to 5 mph wind, running wing on wing. Probably in first stage hypothermia, I recalled William Snaith writing in The Wind's Way about running with the centerboard up to reduce wetted area, during his early 60's trans-atlantic race on Figaro III (he won). So I tried that myself. I got a full extra knot out of my M17. So, question: what other centerboard tricks don't I know? (I have already learned that I tack less at anchor with the centerboard up, and that I "sag to leeward like a pig" when I forget to lower it on a reach.) Second question, for anyone who might have tried it: coming into the docks with almost no wind, we discussed and tried sculling our way to the dock using the Ida-Sail rudder, brought up to just under the surface of the water. It makes a pretty powerful scull. (One of my personal challenges is to sail to and away from the dock with no engine, if possible.) Darned if it didn't work a treat. Anything someone knows about this technique, aside from strain on the tiller head, which I found myself watching, I'd love to hear it. Especially any cautions. As a second season sailor, I need to collect warnings. Thanks, David (M17 #393)
