Big Boat sheaves are engineered for special applications and serve as replacement components for Big Boat blocks. These sheaves are constructed from hardcoat-anodized, Ptfe-impregnated 6061-T6 aluminum to ensure durability and performance. The design incorporates Torlon rollers specifically to handle high radial loads effectively. Additionally, carbon-black Delrin balls are used to support side... read+

These narrow, high-load sheaves are engineered for masthead applications to significantly enhance sail handling efficiency and accelerate sail changes. By reducing friction and load, they enable the use of smaller, lighter halyard winches, contributing to overall weight savings and performance improvements on the water. Optimized Performance: Designed to improve sail handling and facilitate fas... read+

High-load titanium V sheaves feature the same incredibly efficient bearing set of angled titanium rollers as Harken’s V blocks. These sheaves are extremely versatile, perfect for running lines underdeck, in mainsheet and spinnaker sheet or drop line systems. They are also ideal for rigging clean backstay systems to steady today’s slender masts and adjust mast bend.   Bearing System: Featur... read+
