High-Performance Load Management
The Lewmar Racing Double Block is engineered for demanding sailing environments where strength, efficiency, and precise control are essential. Designed for performance cruising and competitive racing yachts, it delivers reliable load sharing and smooth operation in systems subjected to high and repetitive loads.
Double-Sheave Racing Configuration
The twin-sheave layout provides increased mechanical advantage within a compact form, allowing loads to be managed more efficiently with reduced handling effort. Even load distribution across both sheaves improves trimming precision and system responsiveness, making the block ideal for mainsheets, control cascades, and other high-load running rigging applications.
Race-Grade Construction
Manufactured using premium, marine-grade materials and precision engineering, the Racing Double Block is built to withstand sustained static loads, dynamic shock forces, and continuous use on deck. Robust side plates and accurately profiled sheaves ensure structural integrity, resistance to wear, and long-term dimensional stability in aggressive sailing conditions.
Smooth, Low-Friction Performance
Optimised sheave geometry is designed to minimise friction under load, delivering smooth, predictable rope movement during trimming and easing. Reduced energy loss improves overall system efficiency while helping to protect running rigging from unnecessary abrasion during intensive manoeuvres and prolonged sailing.
Installation & Application
Well-suited to high-load trimming systems and performance-focused deck layouts, the Lewmar Racing Double Block integrate seamlessly into modern racing and fast-cruising yacht setups. Its combination of power, efficiency, and durability makes it a professional-grade solution for sailors who demand dependable performance, backed by Lewmar’s established racing hardware expertise.
