Lewmar 90mm Synchro Halyard Block
Lewmar 90mm Synchro Halyard Block
The Lewmar Synchro Halyard Block is engineered for smooth, low-friction handling of high-load halyard systems. Designed specifically for halyard applications, it delivers efficient hoisting and reliable load control at critical mast-base and deck-level lead points. Built with Lewmar’s advanced Synchro bearing technology and durable marine-grade materials, the block provides dependable performance, reduced wear, and long service life. An ideal choice for performance cruising and racing yachts where precision and efficiency are essential.
Features:
Precise Control for Critical Halyard Blocks
The Lewmar Synchro Halyard Block is purpose-engineered to deliver smooth, reliable handling of halyards under high tension. Designed for performance cruising and racing yachts, it provides the confidence and precision required at one of the most load-critical points in the sailing system, where efficiency and durability directly affect shape and rig performance.
Halyard-Optimised Geometry
Specifically developed for halyard use, the block’s proportions and sheave profile are optimised to manage high static and dynamic loads while maintaining accurate rope alignment. This ensures clean lead angles at the mast base or deck level, supporting efficient hoisting, controlled tensioning, and dependable load transfer without unnecessary friction or rope distortion.
Synchro Low-Friction Bearing Technology
As part of Lewmar’s advanced Synchro range, the block incorporates precision bearing technology engineered to minimise friction under load. This results in exceptionally smooth rotation even at high tensions, reducing effort during hoisting and trimming while improving responsiveness and overall handling efficiency in repeated sail adjustments.
Marine-Grade Construction
Manufactured from durable, marine-grade composite materials with robust side plates and a carefully profiled sheave, the Synchro Halyard Block is built to withstand sustained halyard loads, saltwater exposure, and frequent cycling. Its construction ensures dimensional stability and long-term reliability in demanding offshore and performance sailing environments.
Consistent, Dependable Performance
Optimised rope paths and efficient load distribution allow the block to deliver predictable, low-friction performance throughout its working range. Reduced energy loss helps protect halyards from unnecessary wear, supporting consistent sail handling and extending the service life of running rigging across intensive sailing programmes.
Installation & Application
Ideal for mast-base, deck-level, and high-load deflection points, the Lewmar Synchro Halyard Block integrate seamlessly into modern performance rig layouts. Suitable for new builds and professional refits, it offers a refined, professional-grade solution backed by Lewmar’s long-standing expertise in sail-handling and deck hardware.
