Harken Roller Reefing - Furling Units

The long time industry standard for high performance furling systems has been designed for simplicity and competitive pricing and has been divided into 3 updated products. The MK IV unit is designed for racers and performance oriented sailors and the Cruising line is for the serious offshore cruiser. The Harken MKIII #00 AL is designed for smaller boats with most of the same featueres as the MKIV Units.

Most units still feature the double swivel system that helps flatten the headsail as it is reefed and Torlon Bearings to reduce friction for easy furling and low maintenance.

All furlers are shipped with a picture book instruction manual that is simple and clear for owner installation. The MKIII#00AL, MK IV and Cruising units use your existing headstay and turnbuckle for installation.

MK IV Units feature double grooved aerodynamic foils & split removable drums for racing.

Cruising Units have single groove roundfoils to promote easy furling.

• Torlon Ball bearings for low friction & low maintenance
• Double Swivel for reduced sail draft and flatter reefing
• Molded split drum for easy race conversion
• Airfoil shaped extrusions for low aerodynamic drag
• Easy owner installation using common hand tools
• Furling Line is included (lead block kit optional below)

Custom Replacement Heastays
Harken MKIV and Cruising Units will usually require shortening or replacing the headstay for installation because of the added length of the toggle at the bottom. Often customers will replace the headstay at that time, especially if the rigging is more that a few years old.

To replace your headstay when installing your new furler call us with your “pin to pin”dimension. (The dimension between the center lines of the clevis pin holes at the mast head connection and the stem fitting at the bow of the boat (with turnbuckle in normal adjustment). Also provide wire diameter and pin sizes both top and bottom. Custom headstays take about 3 - 5 Days to make.


Replacement Costs are As Follows:
Wire Size Net
1/8 - 3/16” $3.75/Ft
1/4” - 9/32” $4.25/Ft.
5/16” + $4.95

(Headstays are sold with
furler purchase only)

These common boats listed above usually require headstay replacement when installing either Harken #00ALor CDI FF2 Units. If the existing head- stay has a teardrop shaped thimble swaged at the bottom, it will not pass through the foil for installation. Therefore it must be replaced.
