Description

72mm Synchro Block - Single Lewmar's Synchro Blocks are engineered for speed, efficiency, and superior handling. Using a combination of scientifically optimized block geometry, a Free-Spin bearing, and a self-aligning head to reduce friction and increase efficiency by up to 40%, over budget blocks on mainsheet systems.

Each component is perfectly synchronized with the movement of the rope, providing you with an easier, smoother transfer of power from deck to sail and less wear on your rope. Features: Stainless steel strap for improved strength and longer service life Stiff glass fiber reinforced cheeks to prevent lines from wedging Innovative design with “tool-free” sliding swivel locking mechanism Technical Specifications: Working Load Limit - 2420lb Weight - 6.

Sailing — frequently asked

How do I size a block for my sailboat?
Match the block to the line diameter it will carry and to the working and breaking loads of the system (sheet, halyard, control line). Makers publish load ratings and line-size ranges — choose a block whose working load comfortably exceeds the real-world load, without going so large it adds needless weight.
What is running rigging?
Running rigging is the moving lines that control the sails — sheets, halyards, and control lines — as opposed to standing rigging (the fixed wire that holds up the mast). Running rigging should be matched to the boat’s blocks, clutches, and winches for smooth, reliable sail handling.
How do I maintain sailboat winches and hardware?
Rinse with fresh water after sailing, keep sheaves and bearings clean, and periodically service winches (disassemble, clean, and re-grease per the maker’s instructions). Marine-grade stainless and good maintenance keep hardware working smoothly when loads are high and timing matters.
