Harken Small Boat Captive Ball Traveler Cars are used
on large dinghies, keelboats, beach cats and
offshore boats to 27 ft (8 m). The one-piece solid
aluminum construction is lightweight and strong.
Ball bearings run on machined aluminum Hardkoteanodized
races for smooth trimming and easing.
Stainless steel wire guides keep the balls captive
when the car is off the track.
The Harken 2731 Car
uses high-strength Torlon® balls.
