Sheaves

Big Boat sheaves are engineered for special applications and serve as replacement sheaves for Big Boat blocks. Constructed from hardcoat-anodized, Ptfe-impregnated 6061-T6 aluminum, these components are built for durability. They incorporate Torlon rollers to handle high radial loads effectively. Carbon-black Delrin balls are included to support side loads and provide UV protection. Material: H... 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+
