Traveller

A traveller is a deck fitting on a sailboat consisting of a car that slides along a transverse track (often called a horse). The mainsheet block is attached to this car, allowing the sheet's attachment point to be moved athwartships. As noted by Wikipedia, a traveller provides a moving attachment point for a rope or sail, enabling independent control of sail shape. Unlike a fixed padeye, the traveller lets the sailor adjust the angle of attack and twist of the mainsail separately. When sailing upwind, the car is pulled to windward to maintain proper sail shape and pointing ability; off the wind, it is eased to leeward to reduce heeling and weather helm. Handling the traveller often involves lines led to winches, a topic covered in our guide Yacht Rope Handling: Winches and Blocks for Beginners. Proper traveller adjustment is critical during maneuvers like tacking and gybing, as it allows quick adaptation to the new course.
