Features:
Engineered for Maximum Load Demands
The Lewmar High Load Racing Single Block is purpose-built to perform under extreme loads in high-performance sailing environments. Designed for competitive racing yachts and serious performance cruisers, it delivers uncompromising strength, efficiency, and reliability where critical load-bearing hardware must perform without fail.

The single-sheave configuration provides a clean, direct lead with minimal complexity, making it ideal for high-load deflection, halyard handling, and control systems where precision and predictability are essential. Its compact form allows powerful load management while integrating neatly into space-conscious racing deck layouts.
Race-Grade High-Load Construction
Manufactured using Lewmar’s premium racing-grade materials and engineering processes, the block is built to withstand sustained static loads, dynamic shock forces, and continuous use offshore. Reinforced side plates and a precision-engineered sheave deliver exceptional structural integrity, dimensional stability, and long service life in aggressive sailing conditions.
