Features:

Compact Precision for Advanced Control Systems

The Lewmar Synchro Block Single with Fiddle, Becket & Cam is engineered to deliver refined control, increased mechanical advantage, and secure line management within a compact footprint. Developed for performance cruising and racing yachts, it provides a highly integrated solution for fine-tune and cascade systems where precision, responsiveness, and reliability are essential.

Fiddle Configuration with Integrated Becket

The fiddle arrangement delivers enhanced purchase in a space-efficient vertical format, allowing higher loads to be managed smoothly with reduced effort. An integrated becket provides a fixed termination point for control lines, supporting clean, compact cascade systems and ensuring consistent load transfer throughout the control circuit.

Positive Cam Cleat Control

Fitted with an integrated cam cleat, the block allows rapid, secure engagement of loaded lines with controlled, predictable release. This enable fine adjustments to be locked off instantly without reliance on additional deck hardware, improving ergonomics and efficiency at the trimming position during high-workload manoeuvres.

Advanced Synchro Bearing Technology

As part of Lewmar’s Synchro range, the block incorporates precision bearing technology engineered to minimise friction under load. This delivers exceptionally smooth rotation, reduced trimming effort, and enhanced responsiveness, key benefits in performance sailing environments where repeated accurate control is critical.

Marine-Grade Composite Construction

Manufactured from durable, marine-grade composite materials, Synchro Block Single with Fiddle, Becket & Cam 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 conditions.

Installation & Application

Ideally suited to fine-tune controls, control cascades, and secondary trimming systems, the Lewmar Synchro Block Single with Fiddle, Becket & Cam integrates seamlessly into modern performance deck and cockpit layouts. Its combination 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.
