The Under-Deck Furler’s spool is mounted beneath the deck to minimize windage and provide a clean, uncluttered bow with easy anchor access. The tack of the sail is at deck level, allowing wind to flow smoothly across the sail and bow for efficient forward power. The headstay disconnects from the drum so the lower unit can remain in place. The unit is perfect for performance racers and cruisers who require highly aerodynamic systems and a minimal amount of equipment above deck.
