Lewmar 60mm Synchro Block - Single

Upgrade your rigging with the Lewmar 60mm Synchro Block Single, a game-changer for sailors seeking lightning-fast line handling without the hassle. This compact powerhouse combines cutting-edge engineering with practical design, making it ideal for high-performance setups where every second counts. Whether you're tweaking your mainsail on a race course or fine-tuning a spinnaker sheet during a coastal cruise, this block delivers smooth, effortless operation that minimizes rope wear and maximizes control.

Engineered for Peak Efficiency

Lewmar's Synchro series stands out by synchronizing every element— from the sheave to the head—for seamless rope flow. The innovative Free-Spin bearing spins independently of the load direction, slashing friction and boosting efficiency by up to 40% compared to standard blocks. This means less effort hoisting or easing lines, especially under dynamic loads like gusty winds. Sailors report noticeably quicker responses during maneuvers, turning potential struggles into fluid precision.

Standout Features That Make a Difference

• Stainless Steel Strap: Corrosion-resistant and incredibly tough, it withstands harsh marine environments, extending the block's lifespan even in saltwater exposure.
• Glass Fiber Reinforced Cheeks: Ultra-stiff construction keeps lines perfectly aligned, preventing jams or wedging that plague lesser blocks during heavy use.
• Tool-Free Sliding Swivel Locking Mechanism: Snap it open or closed effortlessly—no wrenches needed—for quick swaps or adjustments on the water.
• Self-Aligning Head: Automatically orients to the rope's pull, reducing chafe and ensuring even wear distribution for longer rope life.

These details aren't just specs; they're solutions to real-world sailing frustrations, crafted from years of feedback from competitive and recreational sailors alike.

Performance in Action

Picture this: You're in a tight tack, mainsail loaded. Traditional blocks bind slightly, costing precious time. The Synchro Block's geometry and bearings glide the line as if it's on ice, transferring power directly from deck to sail with minimal resistance. It's particularly brilliant for mainsheet systems, where rapid easing and trimming are routine. Independent testing highlights its edge in speed and low friction, making it a favorite among dinghy racers and offshore adventurers who demand reliability without bulk.

Perfect Fit for Your Sailing Needs

This single block with swivel head shines in versatile roles—mainsheets, traveler cars, cunninghams, or downhauls on boats from Optimists to 40-foots. Its 60mm sheave handles lines up to 10mm flawlessly, supporting a robust working load limit that covers most club racing and family cruising demands. Mount it via the swivel shackle for flexible positioning, and enjoy non-ratcheting freedom in any direction. No becket or cleat keeps it sleek and lightweight at just over 4 ounces, so it won't weigh down your setup.

Care and Longevity Tips

To keep your Synchro Block performing like new, rinse with fresh water after every sail to flush salt and grit. Inspect bearings periodically; their low-maintenance design means simple lubrication restores peak spin. Avoid shock-loading by easing lines progressively, and pair with quality low-stretch rope for optimal results. With proper care, it'll outlast budget alternatives by seasons.
