Experience precision headsail control with the Harken MKIV Unit 1 Furling System (7411.10) — engineered for racers and performance cruisers who demand strength, speed, and reliability. Designed without a toggle, this furling unit combines lightweight, aerodynamic construction with the renowned quality and innovation Harken is known for.

Built for longevity and ease of use, the MKIV system lets sailors quickly furl and reef from the safety of the cockpit while maintaining optimal sail shape and upwind performance. Its free-rolling design ensures effortless operation under load, making it ideal for both competitive and cruising applications.

Key Features

  • Strong, Lightweight & Aerodynamic: Built with precision-engineered components for maximum performance and control.

  • Durable Hardkote Finish: Swivels, torque tube, and aluminum line guard are deep-saturation Hardkote anodized and urethane coated for superior UV and corrosion resistance.

  • Smooth Operation: Multiple rows of Torlon® ball bearings minimize friction; bearings require no lubrication or seals.

  • Performance-Focused Design: Independent halyard and tack swivels improve sail shape and pointing ability during furling.

  • Easy Installation: Fits a range of headstay configurations — swage, rod, Norseman, or Sta-Lok terminals.

  • Flexible Setup: Optional long link plate assembly raises the drum to clear anchor gear for performance cruising.

Specifications

  • Typical Boat Length: 28–36 ft

  • Headstay Diameter (Wire): 1/4", 9/32", 5/16" (6–8 mm)

  • Rod Rigging Diameter: -8, -10, -12 (5.72–7.14 mm)

  • Clevis Pin Diameter: 1/2" or 5/8"

  • Standard Headstay Length: 45' 11" (13.99 m)

  • Maximum Headstay Length: 52' 11" (with optional 7' foil section)

Installation Notes

A toggle assembly (sold separately) may increase forestay length by approximately 3", which may require shortening or replacing the existing headstay. Replacing the headstay during installation ensures correct length and long-term reliability.
