Harken worked closely with Grand Prix yacht designers to adapt its famous Battcar mainsail management system for VO70s and the largest competitive multihulls ever built. These elite teams chose Battcars for their simplicity, reliability,and lightweight design.
All the Volvo teams have switched over, since you can reef or raise the mainsail while surfing in waves at 20 knots without slowing down the boat," explains Mark Wiss, Global Sales and Marketing Director and Grand Prix Manager. "The system also requires less weight aloft since it uses headboard locks with minimally sized halyards."
The GP2 system is on its second successful generation in the Volvo Ocean Race. It also appeared on the Luna Rossa STP65. The GP3 system was used on the 30 m (98 ft) Super Maxi Speedboat, the 31.5 m (103 ft) multihull Groupama 3, the pre-wing BMW Oracle trimaran, and the 40 m (130 ft) multihull Banque Populaire V, the largest racing multihull in the world.
Halyard locks on the headboard remove stressful compression loads from the mast. Track can be bonded to the mast using an exceptionally lightweight adhesive with extremely high fatigue and impact resistance. High-load track is installed in high-stress areas and lighter track reduces weight in other locations. Cars are machined from solid 6061-T6 aluminum. Captive Torlon® ball bearings nearly eliminate friction, while the simple construction makes maintenance easy.
