Lewmar Size 1 genoa lead car systems are popular on racing and cruising yachts. They provide enough load capacity and mechanical advantage
to operate on boats up to 38' (11.5m). These genoa and jib cars are available with either low-friction slide rods and plungers or with ball-bearings.
Ball bearing cars are recommended for systems that will be adjusted under load. Lewmar Size 1 drilled track is 23mm wide.
