Traveller (Sail Control)

A movable car, ring or fitting that changes the position from which a sheet or control applies its load.

A mainsheet traveller commonly runs across a track to alter the boom’s lateral position while retaining chosen sheet tension. Travellers are also used on headsail tracks, horse arrangements and other rigging systems, with adjustment by tackles, stops, pins or powered controls.

Track, car, bearings, end stops, fasteners and control lines carry concentrated loads. Movement can be sudden when a stop or cleat releases, so hands must remain clear of pinch points and adjustment should use the designed control.
