Lewmar Blocks

Lewmar's high-performance Control Blocks are extremely lightweight and have excellent load-bearing capacity. The weight advantage comes from a combination of MRT (Metal Replacement Technology) and stainless steel central race and balls. Long Fiber Technology provides exceptional strength and durability.

Lewmar Racing Blocks are designed to achieve the best strength-to-weight ratio within legal race limits. Composite sheaves run on dual Delrin® ball races. Cheeks are alloy.

Lewmar Synchro Blocks are engineered for speed, efficiency and superior handling. A combination of scientifically optimized block geometry, a Free-Spin bearing, and a self-aligning head reduce friction and increase efficiency up to 40% over conventional mainsheet systems. They feature stainless steel straps and glass-fibre-reinforced cheeks.
