Thanks, all, for the input.
Pokey certainly does wake up with more wind, but we have many races in western LIS in light air. The wind started at around 10 kts, but tapered off from there. The race ended up being cancelled at the curfew as the wind died and the current was actually pushing the leaders out of the bay!
I may have had the genoa sheeted in too far, but I deifinitely was steering to the tails, not adjusting the sails to the course. I'll have to try easing the genoa in light air to see how that works out. I also might have moved the genoa cars forward to get more curve to the sail. I really never move thiose things. I've thought about putting in the Garhauer set up to allow them to be moved under pressure so I could really see how adjusting their position affects us.
