During a race recently my crew and I had some disagreement over how deep to sail the boat toward the leeward mark. We were in a non-spinnaker class, flying a 150 up front. Winds were pretty fluky, ranging from less than 5 kts to gusts of over 20 kts, with the average being around 12 to 15. I know that as the wind gets up it is better to sail more directly for the mark, that heading up does not help a heavy boat as much as it does a light one, and that once the boat is near hull speed heading DDW its VMG is pretty much maxed (for non-planing situations.) Are there any other, perhaps more specific, rules-of-thumb to follow to get best performance downwind? Seth has mentioned heading up a touch with the foresail winged out to the windward side. Any other ideas?
