Harken’s Unit 3 ESP Furler is a strong, durable piece of boat hardware that is currently one of the easiest to install on the market, with an elegant design not available from other manufacturers.

Allowing the user to trim safely from the cockpit when it blows, and unfurl instead of motoring when its light, an adjustable bottom foil fine-tunes the system length, and you can also shackle at the tack and head attach the sail to the furler, with sail shape controlled by halyard tension. The foils are designed to slip over the standard marine eye and headstay wire, which, along with the fact that the wire does not need to be cut, makes installation quick and simple.

Featuring a spool made from hard lube-anodized aluminum, moulded glass reinforced polymers for the cover, flange and guard, and a stainless steel feeder, this ESP Furler is strong, durable and ready to take out on the water.
