Harken Underdeck Furling System
Small Boat Underdeck Furling Units are ideal for sportboats
and daysailers from 4.8 m to 9 m (16 to 30 ft). 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.
An optional hoistable ball bearing halyard swivel can be
installed on your headstay so you can raise or lower the sail
without removing the headstay. Swivels are independent of
the headstay, allowing you to tension the luff separately
from the mast rake. Hoistable swivels work along with
your standard Harken Small Boat furler.
Tack Adapter Tangs
Stainless steel tack adapter tangs are used to adapt clevis
pin diameters on headstays to the standard clevis pin size
that comes on the Harken unit. A third hole accepts lashing
to adjust jib luff tension.
