Harken 13mm Micro deck cars are used on small boats and catamarans. The one-piece solid aluminum construction is lightweight and strong. Torlon® ball bearings run on machined aluminum races with hard anodized coating for smooth trimming and smoothing. Stainless steel wire guides keep the balls captive when the car is off the track. Make the replacements you need for your cars with spare parts from Harken. Harken car chargers are used to replace ball bearings in older non-CB Harken car systems. Technical assistance is available to help you determine your magazine size - race once with Harken Windward Sheeting Scooters and you'll never race without one again. Pull the car above the center line without releasing the leeward control line. The tack and the car remain in the same position, ready to be pulled to the new windward side.
