A ball bearing underdeck furler minimizes windage and provides a clean, uncluttered bow for daysailers and performance racers. It also allows the foot of the sail to graze the deck for improved sail shape and power. The through-deck ball joint provides a low-profile, nearly watertight system. As an option, add a hoistable ball bearing halyard swivel to raise and lower your sail without removing the headstay. Click here for a PDF Brochure.
