Hi Edd, I would think each boat is unique and sail trim and sail condition and swells can have some impact on how much centerboard is needed. Wonder if you could test speed and pointing by going sailing and using GPS and other instruments under different conditions and make your own guide that would work for your boat and your sails? There's probably an AP for that.
Go sailing in steady wind. Get her sailing hard on one tack as usual, sails trimmed and autohelm steering. Then raise the board slowly in increments until you see slipage, then lower back down slightly? Maybe there is a telltale sign when slippage occurs. Maybe she heels less and tries to stand up, and the GPS should show a course change.

Most of the time, we're board-down for upwind sailing and board-up for downwind, but lately I'm noticing that in light air, it may make sense to keep the board up upwind to reduce drag. Or does part-way down make sense? What are your thoughts? All the best, Edd Edd M.
