60mm Synchro Fiddle Block - Swivel, Becket

Lewmar 60mm Synchro Fiddle Block - Swivel, Becket

The Lewmar Synchro 60mm Fiddle Block with Swivel and Becket is a high-performance plain bearing block engineered to deliver racing-level efficiency at a cruising price. Using a combination of scientifically optimized block geometry, a unique Free-Spin bearing, and a self-aligning head, the Synchro range reduces friction and increases efficiency by up to 40% over conventional blocks. Every component is perfectly synchronized with the movement of the rope, providing an easier, smoother transfer of power from deck to sail while minimizing wear on both the line and the block.

The fiddle design allows for a higher mechanical advantage and a more compact system, while the integrated becket enables 3:1, 4:1, or 5:1 purchase configurations for mainsheet and boom vang applications. The swivel head rotates 360 degrees with a tool-free sliding locking mechanism that also offers fixed positions at 0° and 90° to the sheave axle, each with 30° of rotational float for self-alignment. The stainless steel sheave with Delrin bearings ensures low friction and durability in demanding marine environments. Stiff glass fibre reinforced cheeks guide the line and prevent wedging, while the stainless steel strap framework maximizes block strength while minimizing overall weight. This block is standard equipment on newer racer/cruiser sailboats including Beneteau.
