The Lewmar 60mm Synchro Single Block with Becket is a precision-engineered sailing block designed for smooth, low-friction line handling in performance and cruising applications. The integrated becket provides a fixed attachment point at the base of the block, enabling multi-part purchase systems without additional hardware.

Built with a high-density, free-spin plain bearing and a self-aligning head, this block reduces friction and maintains efficiency even as lead angles shift under load. The patented shackle post lock makes rigging fast and secure, while stainless steel straps and glass-fibre reinforced cheeks deliver the durability needed for saltwater use.

Parts Desk Insights

The single-with-becket configuration is the workhorse of 2:1 purchase systems — most commonly used as the lower (moving) block in a mainsheet or vang setup, where the becket anchors the standing end of the line. At 60mm, this block is well-matched to 8–10mm control lines on boats in the 30–40ft range. If you're building a complete purchase system, pair it with the Lewmar 60mm Synchro Double Block at the fixed end for a clean, efficient 3:1 system.
