A sailboat traveler apparatus with bearings having a circular cross section at their pivots which are received in a track with a circular cross section with the traveler carriage being pivotal about the centerline of the track so that pivoting forces on the carriage remain transferred to the bearing surfaces of the bearings and track without binding. The bearings may be spherical or cylindrical depending upon the desired friction between bearing and track. |
