At the MidWinters last month in San Diego, we had a 15+ kt day on the Sunday. We rigged the boat to our moderate wind specs, but I went a bit tighter with the jib slot opening and kept its leech tension higher than I normally do (had a lighter crew than usual).

While double trapping before start at in first weather leg of race one, I heard a whistling sound from the front of the boat/jib. Definitely NOT rudder or board hum...my blades are extremely fine and never hum (which is slow). The sound I immediately recognized as what I had heard a few years ago in Miami at the Olympic Class Regatta when being overtaken by a pro/coached team from France. At MidWinters, our boat performs well upwind against the I20's in that kind of breeze, so it's hard to know if the whistling was a good thing. Sure felt fast as ever...and since the Pro teams were tuning to that point, can it be a bad thing?

Mike.
