High Load Racing Single Block

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.

Single-Sheave Performance Design

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.

Smooth, Low-Friction Operation

Despite its impressive load capacity, the High Load Racing Single Block is engineered to minimise friction and energy loss. Optimised sheave bearings ensure smooth, efficient rope movement under tension, supporting fast hoists, controlled easing, and reduced wear on high-load lines.

Installation & Application

Designed for fixed or articulated mounting within high-load racing systems, the Lewmar High Load Racing Single Block integrates seamlessly, into mast-base hardware, deck deflectors, and loaded control networks. Ideal for halyards, sails, and rigging controls, it represents a professional-grade solution backed by Lewmar’s proven racing and deck-hardware expertise.
