Lewmar 72mm Synchro Single Block with Fiddle

Lewmar 72mm Synchro Single Block with Fiddle

The Lewmar Synchro Block Fiddle provides increased mechanical advantage in a compact, space-efficient design. Its fiddle configuration allows heavy loads to be handled smoothly with reduced effort, making it ideal for control cascades and fine-tune systems. Built with Lewmar’s advanced Synchro bearing technology and durable marine-grade materials, the block delivers low-friction performance and dependable strength. A proven choice for performance cruising and racing yachts requiring precise, efficient control line management.

Features:

Increased Control in Compact Systems

The Lewmar Synchro Single Block with Fiddle is engineered to deliver smooth, efficient load management where increased mechanical advantage is required without sacrificing space or responsiveness. Designed for performance-focused sailing systems, it provides confident, precise control in trimming and fine-tune applications on both racing yachts and high-performance cruisers.

Fiddle Configuration for Mechanical Advantage

The fiddle block layout allows two sheaves of differing size to be combined in a compact vertical format, creating increased purchase within a minimal footprint. This configuration enables heavier loads to be managed with reduced effort, supporting progressive adjustment and precise sail control in high-load control cascades and trimming systems.

Advanced Synchro Bearing Technology

As part of Lewmar’s Synchro range, the block features 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 adjustment and high-workload manoeuvres common in performance sailing.

Marine-Grade Composite Construction

Manufactured from durable, marine-grade composite materials, the Synchro Block Fiddle is built to withstand sustained loads, saltwater exposure, and frequent cycling. Robust side plates and carefully profiled sheaves provide dimensional stability, wear resistance, 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 protect running rigging from unnecessary wear over extended sailing programmes.

Installation & Application

Ideally suited to control cascades, fine-tune systems, and other application requiring increased purchase, the Lewmar Synchro Block Fiddle integrates seamlessly into modern performance rig and deck layouts. Its balance of power, refinement, and compact design makes it a professional-grade solution, backed by Lewmar’s long-standing expertise in sail-handling hardware.
