Unit 2 MKIV Electric Conversion Kit with Control Box

The HARKEN Unit 2 MKIV Electric Conversion Kit represents a transformative advancement in electric jib furling systems for serious cruising sailors. This 12V marine conversion solution breathes new life into existing MKIV Unit 2 manual furling systems by adding powerful electric operation without requiring a complete system replacement. For boat owners managing large headsails on extended cruises, this electric furler conversion delivers the convenience of push-button headsail control from the safety of the cockpit. The system maintains the proven mechanical reliability generations of sailors have trusted while unlocking the operational efficiency of modern electric headsail control systems. Whether you're sailing solo, short-handed, or simply seeking to reduce physical demands in challenging conditions, this retrofit jib furler addresses the real challenges cruising sailors face daily.

The engineering behind this electric furling system reflects Harken's decades of marine hardware expertise, with particular attention paid to the demands of large sailboats operating in diverse wind conditions. The high-efficiency 12-volt DC motor delivers consistent torque across a wide RPM range, handling extreme reefing loads that traditional manual systems require significant physical effort to manage. The integrated electromagnetic solenoid control system operates smoothly through intuitive digital switches, providing variable-speed control that responds to your specific needs. With a 40-amp circuit breaker protecting your boat's electrical system and Torlon bearing assemblies minimizing friction throughout the mechanism, this electric jib reefing solution performs reliably in saltwater marine environments. The system seamlessly integrates with your existing headstay configuration, whether you're running 1x19 stainless steel wire or rod rigging on boats ranging from 35 to 46 feet.

What truly sets this electric headsail control system apart is how it enhances safety and crew flexibility while reducing fatigue on extended passages. Single-handed sailors and short-handed crews benefit enormously from eliminating the physical demands of manual furling line tension. Your crew remains safely in the cockpit with improved visibility for boat handling rather than venturing forward in challenging conditions. The system accommodates sailors of varying physical abilities, making your boat more accessible to family members or guests who might struggle with traditional manual reefing. For charter operations and performance cruising yachts, this conversion kit simplifies crew training while maintaining the operational efficiency that modern sailing demands. Installation complexity is minimized through toggle-based mounting and seamless compatibility with your existing mechanical furling unit, preserving your investment while delivering automation benefits that transform your sailing experience.
