The Harken 3368AL 6.5T Wide V Loop AL Block introduces a new level of efficiency for Grand-Prix racers with its innovative design. By combining axial and thrust bearings into a single V-shaped titanium roller bearing set, Harken engineers have simplified the mechanics and created a lightweight yet strong block. This block boasts exceptional performance under high loads and smooth easing in light air with its free-spinning design. It features aluminum sideplates, a titanium sheave, and captive titanium roller bearings, which can easily be disassembled for inspection and maintenance. The wide sheave allows for multiple lines for sail changes or a single, high-load larger line with small deflection. Part number 3368AL, this block has a sheave Ø of 82 mm (3 1/4 in), maximum line Ø of 16 mm (5/8 in), and a maximum working load of 6500 kg (14300 lb).
