The ESP furling system Unit 0 is the perfect companion aboard yachts between 20 and 28 feet in length. The system has been designed to be DIY friendly without compromising the professional elegance of a Harken product.


The unit can accomodate a maximum headstay length of 12.92m when purchased with an additional 2m foil and connector. The standard kit comes with enough foils to make a 10.92m kit.


The kit will fit a maximum headstay diameter of 5mm or -4 rod. The legs underneath the drum can be supplied ready to take either 8mm or 9.5mm pins.

Harken ESP 0 plus factors:

Easy installation is achieved by slipping the foils on over the standard marine eye.
There is no need to cut the wire during installation. The adjustable bottom foil fine-tunes the system length.

The spool is made from Hard Lube-anodised aluminum.

The cover, flange, and guard are moulded from glass reinforced polymers for high strength.

Foils are clear-anodised for durability.

The stainless steel sail feeder is strong and durable.

Long leg kits raise the drum to clear the anchor, reduce sail chafe and increase visibility.

Removable clamp screws allow legs to pivot out of the way for easy access to the turnbuckle. Choose the long leg kit when using a turnbuckle with swage.


The medium leg kit allows for a slightly lower drum in conjunction with a bottle screw. However, there is a maximum bottle screw length that will fit, please call for details.

Choose the short leg kit when the furler attaches directly to a marine eye at the bottom of the stay. Short legs allow the sail to be closer to the deck.

Simple operation - shackle the sail to the halyard swivel and hoist through the sail feeder (with appropriate luff rope) - shackle at the tack and adjust the sail shape via halyard tension.
