Lewmar Synchro Footblocks

Lewmar Synchro Footblocks from Lewmar are engineered for speed, efficiency and superior handling. These blocks suit a range of purposes from performance cruising yachts to specific high-load low-movement applications on racing sailboats. Lewmar uses a combination of scientifically optimised block geometry, a Free-Spin bearing and self-aligning head to reduce friction and increase efficiency by up to 40% over budget blocks on mainsheet systems.

Product Features:

  • Standard and jammer options can be double stacked
  • Two-step jammer action keeps lever close to side of the block
  • Optimised jammer shape holds line central on the sheave
