If the current is flowing across the upwind leg, work on pointing the boat up when it is leebowing you, and visa-versa foot more when the current is pushing the bow down. If it's 14 knots true, set rig tension and sail trim selection to 12 knots anticipating the chopped up race course. Will Keyworth - Always have a team meeting on the way out to the race course, discussing goals for the day. Then on the way in, conduct a teamde-briefing. This is the best way to congeal and improve as a team.
Winds tend to bend around packs, plus it can be distracting for most crews.
The easiest way to remember your fast gears is to develop trimming references for the luff, leech and foot of the jib. The length of the wrinkles in the luff of the sail. This will tell you how halyard tension is affecting sail shape. The leech of the jib relative to the beginning of the taper and the tip of the lower spreader. This will tell you how trimmed you are for a given condition.
