What are the four key elements needed to specify a Furler?

The basic components to a furling system include foil extrusions, a feeder, the upper swivel (in most systems-but not all), the lower drum assembly and a furling line.

How do you install a jib furler?

Attach the furling drum to the attachment point and then attach the jib tack to the top plate on the furling drum, attach the head of the sail into the top swivel forks and then attach the halyard to the top swivel with a shackle. Hoist the sail and tension the luff.

Can you reef a CDI Furler?

The Flexible Furler can be used to both furl and reef your sail in any wind condition. CDI has eliminated expensive features only hard-core racers demand, thereby increasing the system’s reliability while lowering the cost.

How much furling line do I need?

The length of line going on/off the drum is simply the length of the sail foot. Then you just need enough line to run back to the cockpit and a spare rope tail.

How do you stop a halyard wrap?

One is to fit a bullseye fairlead two to three inches below the sheave box, and lead the halyard through that before making it fast to the swivel. This will open up the angle the halyard makes with the headstay to 10 degrees or more and prevent it from wrapping around it.

How does a furling mainsail work?

Unlike a traditional mainsail that is hoisted and doused vertically with a halyard, an in-mast furling mainsail wraps around a tube inside a hollow mast. It is unfurled by an outhaul line and furled back in with a line labelled as the “inhaul.”

How long should a furling line be?

You may lead the furling line halfway down the side deck and directly into the cockpit or almost down to the transom, around a turning block and into the cockpit. As a rule of thumb, we therefore use the boat length, plus 20% as a tail.

How long should my furling line be?

How are furling lines measured?

What size are furling lines?

This is usually recommended by the manufacturer in the reefing manual but is effectively limited by the capacity of the drum – most reefing lines are normally 6mm, but sometimes they are 7mm (not commonly available as a line size) or on larger drums/yachts the diamater is likely to be 8mm.
