Harken MKIV Roller Furling
Units are designed for owner installation
Harken
MKIV Roller Furling System designed for performance racing and cruising
sailors, MKIV furling systems are strong, lightweight and aerodynamic,
with the performance features Harken is known for. Longevity, ease
of use and simplicity of installation are crucial components of
the design. These free-rolling furlers make all the difference in
headsail control by allowing racers and cruisers to quickly furl
and reef from the safety of the cockpit, while maintaining great
sail shape and optimal speed.
Aluminum line guard, torque tube and swivels are deep-saturation
Hardkote anodized for strength and durability, with a black additive
for no-fade UV-stabilization and corrosion protection. The line
guard is also powder coated for added corrosion resistance. The
drum cap is engineered from tough polymer resin.
Harken MKIV furling systems feature free-rolling ball bearings,
computer-designed stacked bearing races and large-diameter drums
for smooth reefing and furling. A free-spining, high strength halyard
swivel reduces weight aloft to minimize pitching and heeling. The
double foil grooves allow fast hoist, douses, and sail changes -
ideal for club racing.
Features:
1. Free-Rolling Ball Bearings
Multiple rows of large-diameter Torlon ball bearings in high load
areas of the halyard swivel and drum minimize friction for smooth
furling; require no lubrication or isolation seals.
2. Strong Foil Joints
Thought triple-interlock foil joints withstand years of torque loading.
Connector's geometric shape interlocks to foil and secures with
a syringe-injected adhesive into an engineered channel. Screws provide
final lock.
3. Easy to Assemble Foils
C-shaped open connectors with low-friction plastic isolators slip
onto the headstay wire and into foil for easy installation.
4. Drum Installs Over Existing Turnbuckle
Units are adaptable to a variety of rigging options for easy installation.
Harken toggle to assembly accepts standard turnbuckle using swage,
rod, Norseman or Sta-Lok terminals. Toggle flips for fork or tang
chainplate installation. A single stainless steel clevis pin provides
access to the turnbuckle for adjustment.
5. Stainless Steel Feeder
Stainless steel feeder allows fast single-handed hoist and quick
sail changes.
6. Removable Split Drum
Line guard and spool come off easily for racing.
7. Double Foil Groove for Racing
Aerodynamic aluminum Air Foils handle extreme reefing loads. Double
foil grooves allow fast hoists, douses and sail changes.
8. Improved Sail Shape
Independent swivels furl sail center before head and tack for improved
sail shape and smoother furling.
Mauri Pro Sailing recommends the
Harken
MKIV for all your roller furling needs.
