James Lyne, coach to many top teams, emphasizes the lifted tack. In an oscillating breeze, he says, if you sail a header out of the gate or off the starting line, you end up missing the first shift and often end up missing shifts later up the beat. As you sail a header early in the leg, you rapidly get near the layline. If you get to the layline early in the beat you have painted yourself into the corner. Later up the leg, if you get headed, you don't want to tack because you are already on an edge, with not much distance to sail the other way. You have a dilemma because you are still on the long tack, but you are also headed. You end up sailing through a header or two later in the beat, compounding your losses. Those who sail the lifted tack more often are positioned in the middle of the course and don't mind tacking on headers at the top of the beat.
