Features:
Precise Power & Control
The Lewmar Control Block Double with Becket is designed to deliver efficient, controlled handling of high-load control lines where precision and reliability are essential. By combining a twin-sheave configuration with an integrated becket, it enables compact, high-purchase systems that support confident trimming and fine adjustment in demanding sailing applications.
Function-Focused Double Sheave Design
The double-sheave layout provides increased mechanical advantage within a compact footprint, allowing loads to be managed with reduced effort. The integrated becket offers a fixed termination point for control lines, supporting cascade and fine-tune systems that require clean routing, consistent alignment, and efficient load transfer.
Marine-Grade Construction
Manufactured from durable, marine-grade materials, the Control Block Double with Becket is built to perform reliably in harsh onboard environments. Precision-engineered sheaves and robust side plates ensure strength, resistance to wear, delivering consistent performance under repeated load and exposure to saltwater conditions.
Smooth, Reliable Performance
Designed to minimise friction and promote efficient rope flow, the block delivers predictable, controlled movement during trimming and easing. Its stable geometry helps maintain alignment and consistent load transfer, supporting accurate sail control and reducing fatigue during extended sailing or high-workload manoeuvres.
