Favored by skippers and crew, Harken Battcar systems let you raise, douse, and reef the main instantly from the cockpit, even when close reaching in a big breeze. Battcar systems outperform in-mast or in-boom furling, cost far less, and sails don 't need to be recut. High-strength Torlon ® ball bearings circulate smoothly for fast sail hoists, douses, and reefs. Harken now offers an option that allows C-Tech batten receptacles to be used with our Battcar systems. The pintles have shoulders that protect the threads from bending, making them more robust.
