Harken MKIV Unit 1 Furling System, w/Black Anodized Foils, Toggle Sold Separately - For Boats 28'-36'

Nothing beats the MKIV Jib Reefing & Furling line for effortless headsail control and great sail shape for optimal speed. With its ability to reef, simply furl and unfurl instead of changing sails to suit conditions, reduce speed, or gain visibility off the bow. Split drum removes for racing.

Independent halyard and tack swivels furl sail center before head and tack for improved sail shape when reefed.

Precision-extruded, double-groove Air foils for smooth sail handling and fast sail changes.

Specially formulated low-stretch black line is abrasion and UV-resistant; standard on units 0, 1, 2.
