Features:

Compact Control with Added Advantage

The Lewmar Synchro Block Single with Fiddle & Cam is designed for modern sailing systems that demand precise, efficient line handling in a compact arrangement. Developed for performance cruising and racing yachts, it combines controlled mechanical advantage with responsive trimming and secure holding, making it ideal for fine-tune applications where accuracy matters.

Fiddle Configuration for Increased Purchase

The integrated fiddle arrangement provides enhanced mechanical advantage within a small footprint, allowing higher loads to be managed with reduced effort. This configuration supports progressive adjustment and refined control, particularly in cascades and fine-tune systems where smooth, incremental trimming is essential to sail performance.

Integrated Cam Cleat for Positive Control

Fitted with an integrated cam cleat, the block enables rapid, secure line engagement and controlled release under load. This allows lines to be locked off quickly without additional hardware, improving ergonomics at the trimming position and supporting efficient, confident handling during manoeuvres and repeated adjustments.

Advanced Synchro Bearing Technology

As part of Lewmar’s Synchro range, the block features precision bearing technology engineered to minimise friction under load. This delivers smooth rotation, fast response, and reduced trimming effort, enhancing overall system efficiency and handling comfort in high-workload sailing conditions.

Durable Marine-Grade Construction

Manufactured from robust, marine-grade composite materials, the Synchro Block Single with Fiddle & Cam is built to withstand sustained loads, saltwater exposure, and frequent cycling. Reinforced side plates and carefully profiled sheaves ensure structural integrity, dimensional stability, and long-term reliability in demanding onboard environments.

Installation & Application

Ideally suited to fine-tune controls, control cascades, and secondary trimming systems, the Lewmar Synchro Block Single with Fiddle & Cam integrates seamlessly into modern performance deck layouts on racing yachts and fast cruisers alike. Its balance of increased purchase, secure holding, and compact efficiency makes it a professional-grade solution backed by Lewmar’s long-standing expertise in sail-handling hardware.
