MKIII Jib Reefing & Furling System

MKIII Jib Reefing & Furling System

Harken® jib reefing and furling systems are the best in the world. They are aboard more than 50,000 oceangoing yachts, coastal cruisers, and around-the-world racers.

MKIII jib reefing and furling systems are strong, lightweight, and aerodynamic. They feature free-rolling Torlon® bearings, computer-designed stacked bearing races, and large diameter drums for easy reefing and furling. Free-spinning, high-strength Air Swivels® reduce weight aloft to minimize pitching and heeling. Independent head and tack swivels shape the sail when partially furled. Deep penetration Hardkote anodizing ensures years of corrosion resistance.

MKIII jib reefing and furling systems come with New England low-stretch Sta-Set black line and are designed for owner installation.

Seven-year limited warranty.
