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 faster sail changes through reduced friction and load.
Winch Efficiency: Allows for the use of smaller, lighter halyard winches, reducing top-weight and simplifying rigging requirements.
Advanced Load Management: Combines sideload-carrying balls with a Ptfe composite bushing to effectively manage both radial and lateral loads.
