Harken Premium 57mm Double Carbo Air Boat Block Becket

Lightweight and Strong Construction

Our fiber-reinforced composite construction is lightweight yet incredibly strong. This innovative material ensures durability and longevity, making it perfect for demanding sailing conditions.

UV-Stabilized Components

Ball bearings, sheave, and sideplates are UV-stabilized to resist breakdown from prolonged exposure to sunlight. This feature ensures that your components remain robust and perform optimally over time.

Unique Load-Sensing Technology

Our blocks shift seamlessly between ratchet and light air modes without the need for any switches. This unique feature allows for smooth operation in variable winds.

Ball Bearings and Free Rolling

The blocks roll freely in both directions under low loads, ensuring effortless handling. When the load increases, the ratchet assist automatically engages, providing assistance when needed.

Adjustable Ratchet Engagement

The ratchet engagement point is fully adjustable, allowing you to tailor the level of assistance to your muscle power and sailing style. This feature enhances efficiency and precision.

Versatile Applications

Perfect for main/jib sheets and asymmetric spinnakers, our blocks are versatile and designed to meet the demands of various sail types and conditions.

Free Release under Light Load

Under light loads, the blocks offer a free rolling release, making them easy to handle and control. This reduces the risk of snags and tangles during use.

High-Quality Sheave

The eight-sided, hardkote-anodized aluminum sheave ensures smooth and durable operation. The hardkote-anodization adds a layer of protection, extending the life of the sheave.

Conclusion

In summary, our fiber-reinforced composite construction, combined with UV-stabilized components, unique load-sensing technology, and adjustable ratchet engagement, make these blocks ideal for any sailing situation. Their high-quality features and versatility ensure you have the perfect tool for your sailing needs.
