Harken 32mm Big Boat ball bearing traveler 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.
Built in control blocks for 4:1 control lines.
CB wire retaining clips and composite corner keepers keep ball bearings captive when car is off the track. Stand Up toggles hold the mainsheet blocks off the deck.
