The ESP Furler is designed for the cruiser looking for an easy-to assemble furler with an elegant design. Install a Harken® ESP Furler and trim safely from the cockpit when it blows; unfurl instead of motoring when it’s light, for a great day of sailing. 

To make assembly easier, Harken offers top foils in five precut lengths—no hacksaw required. An adjustable bottom foil fine-tunes the unit. Foils slip over most existing headstays without cutting the headstay, reducing set-up time even more. 

Spool is made from Hard Lube-anodized aluminum. Cover, flange, and guard are molded from glass reinforced polymers for high strength. Foils are clearcoat-anodized for durability. The stainless steel sail feeder is strong and durable.
