Harken Big Boat CB Cars

Big Boat Captive Ball Traveler Cars are built to handle high loads on boats from 32 to 50 ft (9.5 to 15 m) and up to 70 ft (21 m) with coupled cars.

The one-piece solid aluminum construction is lightweight and strong. Machined aluminum Hardkote-anodized races permit Torlon® bearings to transition smoothly from the active to return race for smooth trimming or easing. Stainless steel wire guides keep the balls captive when the car is off the track.
