Lewmar 155mm High Load Racing Single Stand Up Block
The Lewmar High Load Racing Single Stand-Up Block is engineered for extreme loads in high-performance sailing environments. Its stand-up design keeps the sheave upright when unloaded, allowing fast, reliable line engagement during manoeuvres and sail trim changes. Built from race-grade, marine-quality materials, the block delivers smooth, low-friction performance with exceptional strength and durability. Ideal for mainsheets, deflectors, and critical control lines on racing yachts and performance cruisers.
Features:
Performance-Led Load Control
The Lewmar High Load Racing Single Stand-Up Block is engineered for high-performance sailing applications where heavy loads, rapid manoeuvres, and absolute reliability are demanded. Designed for racing yachts and advanced performance cruisers, it delivers confident, repeatable line handling in high-stress deck environments.
Stand-Up Functionality for Racing Efficiency
Featuring an integrated stand-up spring mechanism, the block automatically presents the sheave upright when unloaded. This ensures fast, accurate line engagement during manoeuvres, improving handling speed and reducing the risk of missed or tangled leads, an essential advantage in competitive sailing scenarios where efficiency matters most.
Race-Grade High-Load Construction
Constructed using Lewmar’s premium racing-grade materials and design processes, the High Load Racing Single Stand-Up Block is built to withstand extreme static and dynamic forces. Reinforced side plates, a high-strength sheave, and a robust load path combine to deliver exceptional structural integrity, resistance to shock loading, and long-term durability in demanding offshore conditions.
Smooth, Low-Friction Performance
Despite its substantial load-carrying capability, the block is engineered to minimise friction and energy loss. Optimised sheave geometry supports smooth rope flow under sustained tension, reducing wear in high-load lines while enabling precise trimming, controlled easing, and reliable feedback at the helm or cockpit.
