Harken Standard Carbo-Cam Base w/Bullseye

The Harken Standard Carbo-Cam Base w/Bullseye is a precision rigging component designed for sailors, riggers, and marine enthusiasts who demand reliable load management on deck. This compact base unit serves as the foundation for cam-based pulley systems, enabling controlled tensioning and adjustment of lines under load.

Built by Harken—a leader in marine hardware—this component is essential for anyone upgrading or maintaining sail rigging systems that require smooth, repeatable adjustment without manual line slipping. The carbon-composite base construction delivers a lightweight yet rigid platform that resists corrosion and fatigue in saltwater environments. The integrated Bullseye alignment system allows crew to lock lines at consistent tension points without guesswork.

This Harken base is ideal for cruising sailors, racing crews, and retrofit installations on mid-sized sailing vessels where line control and deck space are both priorities. Installation integrates with standard marine stainless fasteners and fits common deck-mounted hardware patterns, ensuring compatibility with various setups.
