Harken’s award-winning Switch T-Track Battcar system cuts the stack 
height of mainsails on large yachts by half, making it much easier for 
crew to put on sail covers and to connect/disconnect halyards. This 
simple, yet sophisticated patented switch system neatly stacks cars 
side-by-side on top of the boom. The unique switch plate has no 
moving parts, ensuring an exceptionally reliable and efficient product. 
Available in 18, 26, 32, and 40 mm sizes for monohulls 11 m (37') to 
over 43 m (140'); multihulls 9 m (30') to over 27 m (90').
