Big Boat CB traveler cars handle high loads on boats from 9.5 m to 15 m (32 to 50 ft) and up to 21 m (70 ft) with coupled cars. Harken ball bearing traveler and genoa lead cars with multipart purchases allow easy adjustment of loaded sails from the cockpit. Whether racing or cruising, these smooth-rolling systems pay huge dividends in sail control and are safer and faster than playing the sheet. CB wire retaining clips and composite corner keepers keep ball bearings captive when car is off the track. Track comes in low- and high-beam configurations.
