Prepare to experience the pinnacle of efficiency and performance with the Harken 40mm Single Zircon Block With Becket. These blocks have been meticulously engineered to exceed expectations and deliver unrivaled performance on the water.

At the heart of the Zircon blocks lies an industrial ceramic ball bearing mounted inside caged races, making them the most efficient small boat blocks ever created by Harken. The ceramic material offers remarkable hardness and smoothness, surpassing steel or composite alternatives. As a result, these blocks require less force to start moving, providing a noticeable advantage in terms of responsiveness and ease of operation. The strategically designed cages keep the bearings separated, ensuring they do not bunch up, touch, or impede each other's motion. This configuration maximises the efficiency of the block, allowing trimmers to match sail shapes to new conditions instantly. Each Zircon block is a testament to Harken's commitment to innovation and their relentless pursuit of excellence.

Notably, Zircon blocks utilise industrial ceramic ball bearings that are more than 700% stronger in compression compared to stainless steel balls of the same size. This exceptional strength contributes to the block's exceptional durability and longevity, ensuring reliable performance even under the most demanding sailing conditions. Whether you're a professional sailor or a passionate enthusiast, the Harken 40mm Single Zircon Block With Becket empowers you to feel the speed and acceleration in your sheets like never before. With the sheet led through the Zircon block, you can anticipate changes in wind pressure before they register on instruments, enabling you to react swiftly and make precise sail adjustments.
