Small Boat CB traveler cars fit dinghies, keelboats, beachcats, and offshore boats to 8 m (27 ft). 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. Track comes in low- and high-beam configurations and is predrilled with holes for mounting fasteners.
