Running
Sailing with the true wind coming from close to astern.
On a run, sails are eased well out and a headsail may be blanketed by the mainsail. The apparent wind is normally lighter and farther aft than the true wind because the vessel is moving in the same general direction.
Course instability, rolling and wind shifts can cause an accidental gybe. A preventer, suitable sail plan and deliberate steering can reduce risk, while some boats sail faster and more safely by broad-reaching on successive legs.
