Product Description
Includes: drum and upper swivel.
Harken Small Boat underdeck furling units are ideal for sportboats and daysailers from 16 to 30 ft (4.8 m to 9 m). The drum is located beneath the deck, lowering the tack height for maximized sail area. The single through-deck ball joint provides a low-profile, nearly watertight system that aligns the spool to the headstay. Like all Small Boat furlers, the underdeck furler is for furling only, not reefing.
