MKIV Underdeck Unit 1

MKIV Underdeck Unit 1

Harken’s MKIV Underdeck Jib Reefing & Furling line is the perfect solution for sailors who want an aerodynamic system with a minimal amount of equipment above deck. The underdeck furler provides a low-friction, clean layout solution that minimizes windage, while uncluttering the bow for easy anchor access. Tack sits at deck level, lowering the tack height for maximized sail area. Through-deck bearing into underdeck compartment provides a low profile, nearly watertight system. Typical Boat Length 8.3 - 11 m (28' - 36')
