Lewmar 50mm Synchro Single Block with Fiddle & Becket

Lewmar 50mm Synchro Single Block with Fiddle & Becket

The Lewmar Synchro Block Fiddle & Becket provides increased mechanical advantage in a compact, space-efficient design. Its fiddle configuration allows high loads to be controlled smoothly with reduced effort, while the integrated becket supports clean, effective cascade and fine-tune systems. Built with Lewmar’s advanced Synchro bearing technology and durable marine-grade materials, the block delivers low-friction performance and long-term reliability. Ideal for performance cruising and racing yachts where precise, efiicient control line management is essential.

Features:

Compact Mechanical Advantage

The Lewmar Synchro Block Fiddle & Becket is engineered to deliver increased mechanical advantage and precise load control within a compact, space-efficient format. Designed for modern performance cruising and racing yachts, it provides confident, refined handling in control systems where efficiency and accuracy are essential.

Fiddle Configuration with Integrated Becket

The fiddle block layout combines multiple sheaves in a vertical arrangement, allowing higher purchase without increasing deck footprint. This design enables heavier loads to be managed with reduced effort and greater control. The integrated becket provides a secure termination point for control lines, making the block ideally suited to cascade and fine-tune systems that demand clean routing and compact geometry.

Advanced Synchro Bearing Technology

As part of Lewmar’s Synchro range, the block incorporates precision bearing technology designed to minimise friction under load. This advanced engineering delivers smooth rotation, fast response, and reduced trimming effort, particularly beneficial during repeated adjustments and high-workload sailing manoeuvres.

Marine-Grade Composite Construction

Manufactured from durable, marine-grade composite materials, the Synchro Block Fiddle & Becket is built to withstand sustained loads, saltwater exposure, and frequent cycling. Robust side plates and carefully profiled sheaves ensure dimensional stability, resistance to wear, and long-term reliability in demanding onboard environments.

Smooth, Consistent Performance

Optimised rope alignment and even load distribution across the sheaves promote efficient, low-friction rope flow during trimming and easing. Reduced energy loss improves handling comfort and accuracy while helping to protect running rigging from unnecessary wear throughout extended sailing programmes.

Installation & Application

Ideally suited to control cascades, fine-tune systems, and performance-oriented deck layouts, the Lewmar Synchro Block Fiddle & Becket integrates seamlessly into modern rig and deck configurations on both racing yachts and high-performance cruisers. Its balance of power, refinement, and compact efficiency makes it a professional-grade solution backed by Lewmar’s long-standing expertise in sail-handling hardware.
