Small Boat Furling
Underdeck Furler
A ball bearing underdeck furler minimizes windage and
provides a clean, uncluttered bow for easier mooring and
anchoring. It also allows the tack of the sail to be at deck level
for better sail shape and more forward power. Its single
through-deck spherical joint provides a low-profile, nearly
watertight system that aligns the spool to the headstay. Like
all small boat furlers, the underdeck furler is not suitable for
reefing and it requires a jib with an embedded luff wire.
Swivels must be purchased separately.
Hoistable Swivels
Hoistable ball bearing swivels slide over your headstay and
work in conjunction with your normal upper swivel. Since
normal swivels are attached to the masthead, you usually
need to take down the mast or tip the boat on its side to
detach the sail. By attaching the head of your sail to the
hoistable swivel instead, you can simply lower the swivel with
the jib halyard and unshackle the sail. In addition to making
it much easier to change or remove your headsail, the swivel
is independent from the headstay so it gives you a way to
tension the luff independently of the mast rake. Hoistable
swivels are compatible with any Harken small boat furler.
Furler Kit with Hoistable Swivel
This kit is similar to Harken’s existing 435 high-load furler
kit but includes everything you need for a hoistable halyard
swivel. The kit includes a 164 swivel, HC7744 hoistable
swivel, 165 drum, and a tang to attach the forestay and
sail tack to the lower unit.
