In a previous post, the term "header" was incorrectly defined. Credit to Catey Hale for catching the error. Below is a correct definition of "header" and its opposite term "lift"
Header: a shift in true wind direction more forward on a boat’s sail plan, which
makes the apparent wind stronger and more forward. Upwind, a header
causes you to bear off and to point farther from the direct course to
the windward mark. Downwind, a header has the same effect, which causes
you to bear off and to point more directly at the leeward mark. If you
are sailing upwind and want to point as close as possible to the
windward mark, sail on lifts and tack on headers. If you are sailing
downwind and want to sail tighter and faster down the rhumb line,
sail on headers and jibe on lifts. A header usually arrives in a puff
moving laterally across a boat’s course from forward of the prevailing
wind direction; e.g., fewer than 45 degrees aft of a close-hauled
sailing course. The opposite of a lift.
Lift: a shift in true wind direction more aft on a boat’s sail plan, which
makes the apparent wind lighter and more aft. Upwind, a lift allows a
helmsman to head up or alter course to windward and point closer to the
direct course to the windward mark. Downwind, a lift causes a helmsman
to head up and point away from a direct course to the leeward mark.
Upwind, sail on lifts and tack on headers
so that you point as close as possible to the windward mark. Downwind,
sail on headers and jibe on lifts so that you sail tighter and faster
down the rhumb line.
A lift usually arrives in a puff that moves laterally across a boat’s
course aft of the prevailing wind direction; e.g., more than 45 degrees
aft of a close-hauled sailing course. The opposite of a header.
