Harken ESP Plus Factors:
The Spool inside the drum is manufactured from Hard Lube anodized aluminium.
The Cover, flange, and guard are moulded from glass-reinforced polymers delivering maximum strength : weight ratio.
Foils are clear-coat anodized for durability.
The feeder is produced form hard wearing marine grade stainless steel.
Long leg - Raises the drum to clear the anchor, reduce sail chafe, and increase visibility for smooth sailing.
Choose the long leg kit when using a standard turnbuckle with swage or swageless terminals.
A single stainless steel clevis pin provides access to the turnbuckle for adjustment.
Short Leg - attaches directly to the marine eye at the lower end of the stay. Although most turnbuckles will not fit, it does allow a sail with a longer luff.
Use your existing headstay length and clevis pin diameter combined with the approximate boat length guide to determine which unit is suitable. Take care to note whether you need an extra foil.
Every kit contains all components required to assemble the unit and comprehensive instructions to make everything as easy as possible.Extras such as new stanchion blocks, furling lines, new headstay or rod adaptors are not included in the kit but are readily available from the Jimmy Green Rigging Sales Team.
Choose Furler Type
The table below is only a guideline based on sailing style and approximate boat size.
Determine Unit Size
The Unit Size should be based on the headstay and clevis pin diameter.
Choose between unit sizes when diameters are shared by considering stay length and typical boat size recommendations.
Determine whether Additional Foils are Needed
Use the I and J measurements to determine the length of the headstay.
If the existing headstay is longer than the Harken recommended standard length for that unit, you will require additional foils and connectors.
Determine Leg Kit
Use short leg kits for maximum luff length, long leg kits to accommodate a turnbuckle or to make clearance on deck.
Choose Lead Block Kit and Accessories
Harken recommend a ratchet lead block kit.
More Furling Accessories include equipment for halyard management and hardware for improved sail changes.
Prepare Sail and Forestay
Your Genoa will require a luff tape.
Match the sail length to the stay length minus the height of the halyard swivel and lower unit.
ESP furlers with long or medium leg kits install over the existing turnbuckle.
The turnbuckle is accessible for adjustment by raising the drum.
The forestay may need to be shortened to accommodate the Harken toggle but it may be only the lower threaded turnbuckle that needs changing.
The Jimmy Green Rigging Team are happy to help you determine the appriate Harken unit tailored to your yacht and your intended sailing.
