The Lewmar 60mm Synchro Triple Block is a high-performance sailing block engineered for demanding on-water applications where low friction, smooth operation, and long-term reliability matter. Built with a high-density, free-spin plain bearing and a self-aligning head, this block minimizes friction and maximizes load efficiency — keeping your lines running clean under load.
The patented shackle post lock makes rigging and de-rigging fast and secure, while stainless steel straps and glass-fibre reinforced cheeks deliver the structural integrity needed for offshore and performance sailing alike. Sheave, bearing, pin, and line size are all matched for optimum efficiency at this block's rated capacity.

Parts Desk Insights
This block is the go-to choice for mainsheet and purchase system builds on 30–40ft performance cruiser-racers. The triple configuration provides a 3:1 mechanical advantage, making it ideal for high-load applications where crew effort needs to be reduced without sacrificing response. Pair with a Becket & Cam version at the boom end for a complete mainsheet system. The self-aligning head is particularly valued in vang applications where lead angles shift under load.
