The Harken V block sets a new standard for loop blocks designed for Grand-Prix racers. By combining axial and thrust bearings into one V-shaped set, Harken engineers have created a powerful and lightweight block with exceptional efficiency at high loads. Even at low loads, this block spins smoothly for easy trimming in light air. Featuring 3D-molded carbon sideplates, a titanium sheave, and captive titanium roller bearings, the V block can be easily disassembled for routine maintenance. With a maximum working load of 6500 kg and a sheave diameter of 82 mm, the 6.5T Carbon V™ Block (Part No. 3297) is a reliable choice for high-performance sailing.
