to set a second headsail before dousing the first as a way to maintain speed and respond to wind shifts and wind velocity changes. The new sail is hoisted either outside (behind, from the crew’s perspective) or inside (in front of) the working sail. As the new sail is trimmed in, the old sail is doused. Also referred to as a peel, a running change, or a straight-line headsail change. See also: inside set and outside set. Compare to: bare headed.
