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.

Coupled High Load cars withstand much higher loads than single cars.
