A traveller car for a sailing vessel has recirculating rolling bearings for engaging its running tract (5). A return run of the rolling bearings is provided by a discrete tube (14) set in a body of the traveller car and passing through bores (15) in projections (16) from the body. Two arrays (7,8;9,10) of such bearings may be arranged in load-bearing relationship to each lateral side of the track.
