Lewmar 72mm Synchro Single Block
Lewmar 72mm Synchro Single Block
The Lewmar Synchro Block – Single delivers smooth, efficient line handling with low friction and precise control. Designed with advanced Synchro bearing technology, it provides responsive performance under load, making trimming easier and more efficient. Constructed from durable, marine-grade materials, the block offers reliable strength and long-term performance in demanding onboard environments. Ideal for control line and performance-focused deck layouts on cruising and racing yachts.
Features:
Precision Control for Modern Sailing
The Lewmar Synchro Block – Single is engineered to deliver smooth, efficient line handling in performance-focused sailing systems. Designed for both racing yachts and performance cruising vessels, it provides a refined balance of strength, low-friction, and responsive control where accuracy and reliability are paramount.
Single-Sheave Synchro Design
The compact single-sheave configuration offers a clean, direct lead for running rigging and control lines, supporting predictable load transfer with minimal system complexity. This simplicity makes the Synchro Block – Single ideal for deflection points and trimming applications where consistent performance and ease of handling are required.
Synchro Bearing Technology
Developed as part of Lewmar’s advanced Synchro range, the block incorporates precision bearing technology that delivers smooth, low-resistance rotation under load. This engineering reduces friction, enhances trimming efficiency, and improves overall system response, particularly during frequent sail adjustments and high-workload manoeuvres.
Marine-Grade Construction
Manufactured from durable, marine-grade composite materials, the Synchro Block – Single is built to withstand loads, saltwater exposure, and repeated cycling in demanding sailing environments. Robust side plates and a carefully profiled sheave ensure dimensional stability wear resistance, and long-term reliability.
Smooth, Dependable Performance
Optimised rope paths promote efficient load distribution and consistent rope flow during rimming and easing. Reduced friction not only improves handling comfort but also helps protect running rigging from abrasion, supporting dependable performance over extended sailing programmes.
Installation & Application
Well-suited to control lines, deflectors, and performance-oriented deck layouts, the Lewmar Synchro Block – Single integrates seamlessly into modern rigs on racing yachts and fast cruisers alike. Its balanced design and proven performance make it a professional-grade solution backed by Lewmar’s long-standing expertise in deck hardware and sail-handling systems.The Lewmar Synchro Block – Single delivers smooth, efficient line handling with low friction and precise control.
