Traveler Position, Section 3.5

"When sailing closed hauled on a catamaran in heavier air, move the traveler up wind (on the opposite side of the sail) and let off on the main sheet. This will allow the boom to rise a little and "twist out" the top of the sail. Twisting the sail allows you to let some of the top part of the sail "deflate" in case of slightly stronger winds. In light air, make sure that the top of the mainsail is not "loosing air" meaning, keep the traveler close to the center and tighten the mainsheet pretty good to make sure the main cannot open up at the top. As soon as the breeze kicks up, bring your traveler up a bit more and ease the mainsheet so that the boom does not come past center point." This seems backwards to my logic. I have used the traveler to compensate for the vertical gradient of true wind, i.e. the wind speed at the top of the mast would be higher than lower due to friction of the water surface. By moving the traveler to windward and easing the sheet adds twist to the sail, changing the angle of attack at the top of the sail. In higher winds, moving the traveler to leeward would allow the sail to bleed off the pressure and in the case of a monohull, reduce the heeling.
