Harken’s award-winning Switch T-Track Battcar system is designed to cut the stack height of mainsails on large yachts by half. This reduction makes it significantly easier for crew members to install sail covers and to connect or disconnect halyards. The system utilizes a simple yet sophisticated patented mechanism to neatly stack cars side-by-side on top of the boom. Cars operate on low-friction plastic slides for smooth movement. The components are Hard Lube-anodized and UV-stabilized to ensure long-term durability.
