Our carbon hydraulic Jib Reefing and Furling systems combine the beauty of stainless with the elegant finish of carbon. Stunning to look at, these UV resistant foils have proved themselves over and over in the extreme conditions found in round the world racing and cruising.

Single groove foils are filament wound of standard modulus carbon fiber that maximizes torsional resistance and saves 30 lbs (13 kg) to 200 lbs (90 kg) over their aluminum counterparts. The lower unit features a carbon fiber torque tube and cowling. Sift Spectra line attachments are used for the halyard, head and tack and eliminate the need for heavy welded lugs and shackles.

Harken® Captive Reel winches, produced by James Nilsson Winchmakers, provide a convenient push-button solution for megayachts and large cruising boats. Featuring a one- or two-speed hydraulic motor, they are noted for their reliable design, detailed construction, and quality materials.

Components
Modular construction allows servicing without removing the winch assembly. The Hardkote-anodized frame and components are marine-grade 5083 and 6000 aluminum. Lubricated bearings are sealed and dry-run bearings are made with low-maintenance synthetics.

Gearbox
The hub-drive gearbox inside the 316 stainless steel drum uses precision gearing to time the lead screw for exact line placement.

Switches
Proximity switches prevent over-travel. Automatic failsafe switches shut down the winch completely.

Valve block and tensioner
Mounted onto or independently from the winch, the valve block incorporates a counterbalance valve, brake operating shuttle, and line tensioner. The tensioner spools line onto the drum evenly and keeps it clear of the winch housing.

Keep sheets, halyards and other lines from underfoot with a nylon mesh sheet bag. Sheet bags come with snaps and include mounting hardware. Lifeline bags attach using a hook-loop closure. Both styles feature elastic openings. Available in two sizes small 12"H x 12"W x 2"D and large 12"H x 20"W x 2"D.

Sailing gear closeouts have been moved to our brand new Harken Sport site.

Electric winches offer cruising sailors the convenience of powered winches in an easily installed system. Winches operate using waterproof switches located near the winch. A locking handle—inserted when the winch is not under load—automatically disconnects the electric motor gearbox. The disconnect mechanism prevents winch and handle from rotating while switch is activated.

For very high line speeds under low loads, winches size 60 and larger can be special-ordered with three speeds.

Sizes 44 through 980 are offered for either 12 or 24 volts and mount vertically or horizontally. The anchor plate allows winch maintenance without removing the motor/gear reduction assembly. Both motor and sealed gear reduction box feature anti-corrosion protection.

Before ordering, you need exact rig dimensions. Please contact Harken® if you have questions.

Hydraulic power winches are driven by the boat’s central hydraulic system. The same power source can be used to drive other functions: furlers, vangs, backstays, lifting keels, etc.

Hydraulic winches sizes 60 and larger may be special ordered with three speeds for very high line speeds under low load. The three-speed 1140 has an additional backwind option—useful on large yachts for relieving the load on the winch before releasing the sheet.

Winches operate using waterproof switches located near the winch. A locking handle—inserted when the winch is not under load—automatically disconnects the electric motor gearbox. The disconnect mechanism prevents handle and winch rotation when the switch is activated.

All hydraulic motors mount vertically. All hydraulic fittings are industry standard for ease-of-service with other components.

For sailors who frequently race their boats, we advise using the racing disconnect rod to permanently keep the winch in manual mode.

The low friction, light weight and durability of the twin-groove Carbo Racing Foil is a winning combination! The engineered Carbo material used in the foils provides significant advances over the PVC materials common to other racing foils.

The Carbo Racing Foil material is very low friction making hoists, douses and sail changes faster. Its high strength provides dramatic improvement in resistance to line wear, especially when jibing asymmetrical spinnaker sheets. Impact resistance is increased—less damage from spinnaker poles, especially in cold weather. Heat has little effect on stiffness. The black color provides superior UV protection and is easy to see against a light sky, making the jib trimmer’s job easier.

Because the Carbo foil uncoils and straightens, installation is simple. Snapping the foil onto the stay is easy and can be done with the mast up.

Pedestal-drive winch systems are used for applications demanding speed and power. One or more crew can crank from a powerful standing position. Pedestal systems are customized to meet the specific needs of each boat.

Belt Drive Pedestals
Harken® belt drive pedestals are available molded in carbon fiber/epoxy. Drive components are fabricated of Hardkote-anodized aluminum and 17-4 PH stainless steel. Roller bearings and belt sprockets made of high-performance engineering thermoplastic-reinforced drive belts ensure the lowest possible weight.

In addition to the standard below-deck drives, belt drive pedestals can be supplied in “mid-drive” form. These pedestals not only offer a significant weight savings, but are also useful in building a removable pedestal. To open up cockpit space for long-distance racing or cruising, these systems can be removed in just a few minutes and the winches converted to top action.

MX Pedestal
Use the carbon-fiber MX Pedestal on small Grand Prix boats with pedestal-driven winches. This lightweight pedestal features a patented built-in overdrive system that eliminates bulky overdrive boxes to reduce weight and conserve space belowdeck. Knobs at the base of the pedestal handles control gear ratios, replacing deck-mounted foot buttons and linkage controls.

Micro track comes in low and high-beam configurations. The wide track base adds stability and protects cored decks. A channel on the track bottom makes it easy to install on unfair decks and eliminates rocking on curved surfaces like booms or masts. Fastener holes fit both metric and imperial screws.

16 mm control blocks spin on stainless steel balls that roll freely under high loads. The step-down design keeps the controls low and clear of the mainsheet block.

Super-tough plastic endstops absorb sudden shock loads that can occur during unintentional jibes.

Aluminum Radial winches are designed for sailors who want lightweight, extremely strong winches with plenty of power.

The drum’s gripping surface is shaped for each winch size and drum material and features diagonal ribs (rather than textured abrasive materials) to maximize gripping power and greatly reduce line wear. When easing, the angle of the ribs stops line from rising, preventing overrides and providing a smooth controlled release as the line exits the winch. Aluminum drums and high-strength composite self-tailing jaws and skirt save weight. Composite roller bearings reduce friction under load and don’t require lubrication. Loadcarrying gears and pins are 17-4PH stainless steel for strength and durability.

Small boat winches are available in single speed. Self-tailing models sizes 60 and up come in two or three speeds.

Chrome Radial Winches are designed for sailors that want the elegance of mirror-polished chrome to enhance their yacht’s lines. They feature chrome drums, black composite bases and tops, and come in 1-, 2-, or 3-speed self-tailing styles.

The drum’s gripping surface is shaped for each winch size and drum material and features diagonal ribs (rather than textured abrasive materials) to maximize gripping power and greatly reduce line wear. When easing, the angle of the ribs stops line from rising, preventing overrides and providing a smooth controlled release as the line exits the winch. Highstrength composite self-tailing jaws and skirt save weight. Composite roller bearings reduce friction under load and don’t require lubrication. Load-carrying gears and pins are 17-4PH stainless steel for strength and durability.

Small Boat winches are available in single speed. Self-tailing models sizes 60 and up come in two or three speeds.

Gross-trim/fine-tune mainsheet systems are easy to install and use. For fast trimming pull both tails of the mainsheet. For fine-tuning, pull one tail and the purchase doubles.

Two-speed mainsheet systems come in three configurations for boats from 22 ft to 39 ft (6.5 m to 11.8 m), with mains as large as 3502 (32.4 m2).

We offer carbon furling systems with carbon parts in the drum and torque tubes, and all carbon foils for the ultimate furling. These stunning units will not only increase your boat’s performance, but also add to its beauty.

Carbon foils weigh half as much as conventional aluminum foils—a huge benefit because less weight high and forward not only reduces pitching and heeling, but the amount of lead needed in the keel. Compared to aluminum, a carbon fiber furler will save you from 25 lbs (11 kg) to 200 lbs (90 kg) depending on the size of the unit.

Our Carbon Furlers have a smooth elegant finish and are UV resistant. They are built of standard modulus carbon fiber, the same material used in most carbon masts (T300 or equivalent). The fiber is laid in the direction of the load, with strength optimized for weight. We use high-strength Spectra® cord for tack and head attachments. This “soft” attachment line replaces heavy, reinforced lugs and shackles.

Foils are made of filament-wound carbon to maximize torsional resistance. Single sail grooves are standard but a double groove upgrade may be special ordered. The independent aluminum halyard, head and tack swivels feature “soft attachment” Spectra® line and let the sail center furl before the head and tack for improved sail shape. Built-in turnbuckles make installation and mast tuning easy.

When ordering, you must schedule installation with factory-trained installers. Please specify rod size, clevis pin and headstay length. Foil kits include extra foil and connector. Prices do not include installation. Call for availability.

Easy-Open Ball Bearing Cams
Multiple rows of high-load ball bearings reduce friction so cams open easily for snap-down, rather than draw-through cleating.

The cam horns and smooth V-shape guide line for easy entry. This allows precise sail control without having to readjust the cleated line.

The Teflon® surface of the aluminum Cam-Matic® improves the cleat’s fast line engagement. The Cam-Matic® is the only cleat that will engage under maximum line tension.

Protective Tooth Design
Rounded teeth hold securely by squeezing rather than cutting into line to reduce wear.

High-Wear or Lightweight Models
Aluminum Cam-Matics® are Hardkote-anodized for high-load, high-wear, continuous adjustment applications. Available in Micro, standard and Offshore sizes.

Lightweight fiber-reinforced Carbo-Cams® for racing where weight is critical, or where adjustments are less frequent. Available in Micro and standard sizes.

Long-Lasting Protection
Ball bearings and Carbo-Cams® UV-stabilized with carbon-black additive for maximum protection.

Use these accessories to adapt our cleats for many applications, such as cleaning up your cockpit controls with color-coding or leading a line cleanly to a cleat.

Wire fairleads maintain a low profile while holding the line close to the cleat.

The X-Treme Angle Fairlead allows releasing and recleating at angles up to 90° to the cleat. This sets it apart from other fairleads where line uncleats at extreme angles, and can’t recleat without centering the line. The low-friction stainless bail provides a bulletproof turning point. Perfect for traveler and cabintop controls or deck cleats—a must for the new Laser® deck cleating system.

Low-profile top-mounted flairleads can also be used to guide lines. They feature stainless wearguards and are available in various colors for color-coding your cams. We offer a wide range of eyestraps to hold line at the cleat and to provide fair leads.

Use cam swivel bases when leads must rotate to face the trimmer.

Ball bearing swivel bases feature dual rows of Delrin® ball bearings that swivel freely even under high loads. Bases include stand-up springs and a U-adaptor to accept a variety of appropriate blocks.

The 144 is the standard configuration with a tall arm. It is ideal for mounting in the cockpit or for use on larger keel boats and small offshore boats that use 3.00 in (76 mm) plastic blocks. The low-profile 205 is used when installation is at deck level and when smaller blocks are used. The 1574 accepts Midrange blocks.

The 216 features a second cleat for lines led vertically through the base of the swivel. It is frequently used to combine vang or backstay controls in the same swivel base that handles the mainsheet.

The 240 and 241 are simple swivel bases for main and jib sheets on very small boats or for control lines on boats of all sizes.

The 402 and 403 are fitted with a double cam for use in two-speed mainsheet systems.

The 462 swivel base with 338 Micro Cam-Matic® provides precise cleating. The 16 mm sheaves feature low-friction stainless steel ball bearings to handle high loads. Ideal for controls where cleating angles change dramatically.

Self-contained sheaves are designed for sailors to use in custom applications.

The Micro, Bullet and Big Bullet sheaves are Delrin® with Delrin® ball bearings. They are scored for rope. 16 mm AirBlock® sheaves are Delrin® and feature stainless ball bearings that ride in a grooved race. Midrange sheaves come in either Delrin®, or aluminum for wire.

Wire sheaves ride on high-load composite bearings. They are Hardkote-anodized aluminum with Teflon® impregnation.

Ball bearings in the 11/2 in (38 mm) and 2 in (51 mm) sheaves minimize friction. The 1 in (25 mm) wire sheave uses low-friction washers for this purpose.

Two 160 sheaves make up the 161 dual sheave universal lead. Use this sheave to divert a line that must turn in either direction.

Use ESP sheaves to handle high static loads from halyards and reef lines. Sheaves are carbon-black Delrin® for UV protection, and they turn on stainless steel spacers. Contained sideload ball bearings allow sheaves to spin freely when loads are released. Sheaves require a sideplate for the sideload balls to roll on.

Padeyes are great for mounting blocks and are also used as attachment points for staysails, reefing blocks, and hundreds of other items.

Harken® offers a range of stainless steel padeyes. The diamond-shaped padeyes, 688 and 689, are 316 stainless and often used at mastbases where the diamond shape allows them to be mounted very close together. The 627, 629, and 648 padeyes are 17-4 PH stainless.

For maximum strength always align padeye bails to the load.

Eyestraps are useful accessories. They form light-duty mounting bases for blocks, serve as lash-down points, and can be used for fairleads.

Forged eyestraps are extremely strong and their smooth shape won’t chafe line.

Typical Boat Size:
Monohulls: length to 37 ft (11.3 m); mainsail area under 350 ft2 (33 m2)

Multihulls: length to 30 ft (9.1 m); mainsail area under 275 ft2 (26 m2)

The one-piece solid aluminum construction is lightweight and strong. The free-rolling ball bearing cars let you hoist and reef the main quickly on all points of sail. Cars are easily removed from the track by freeing the screwpin endstop and sliding them off. Stainless steel wire guides keep the balls captive when the car is off the track.

Push-Button Control

Powered winches allow crew to trim any size sail with the push of a button.

While some manufacturers control winch speed by speeding up and slowing down the motor, Harken® motors attach to the central drive shaft so the gears (not the motor) turn the winch for two “true” speeds—similar to using a winch handle. This results in less drain on the battery and a more efficient winch. All Harken® powered winches, including the smaller sizes, operate in two speeds in both powered and manual modes.

Winches come in 12-volt DC, 24-volt DC and hydraulic drive options. Harken® also offers powered winch components: waterproof switches, motor controllers, circuit breakers and hydraulic power units.

1997 and 1998 cars have roller/ball bearing sheaves for easy trimming. The sheave carrier pivots 45-degrees side-to-side, swivels and articulates fore and aft to handle changing lead angles. Cars ride on low friction plastic slides.

The 1997 pinstop lever locks open to move car along the track. The 1998's car-mounted high-load sheave makes a 2:1 adjuster tackle when paired with the B1877 or 1844.

The bevel gear box is the basic building block of the drive system. Harken® offers two versions that work with belt drive pedestals. The B606 and B701 can handle input from more than two people.

The B606 and B701 gear box housings are made of a high-strength aluminum alloy that is Hardkote-anodized for maximum durability. Gears, shafts, and rollers are 17-4 PH stainless steel.

Drive Shafts
Harken® offers two types of drive shafts. Extruded splined aluminum drive shafts may be cut to length. Custom made tubular drive shafts are available with bonded end fittings in carbon fiber/epoxy. Shaft choice is determined by load, cost, and weight considerations. Your Harken® representative can provide details on the best drive shaft for your boat.

Disconnects
System disconnects can be activated with either levers, control lines or a two-position push button. These may be operated by either hand or foot, though the lever and control lines are usually supplied for hand operation and the button is normally operated by foot.

Support Shafts
To properly space and support a gear box beneath a winch, Harken® supplies tubes for the B606 and B701 series gear boxes. Tubes are made to length from high-strength, Hardkote-anodized aluminum alloy, or carbon fiber/epoxy with bonded ends.

Universal Joints
Gear boxes are connected to other gear boxes and pedestals by drive shafts fitted with either a universal joint or a coupling at each end. Our spherical couplings are extremely light but may only be used where the shafts are in-line. Our high angle universal joint is made of aluminum with 17-4 stainless pins, making it very strong and able to operate efficiently at shaft angles up to 25 degrees.
