CDI Furling Systems

For Mainsails, Headsails & Cruising Spinnakers


What Separates A CDI Furling System From The Competition?

Simplicity: Often, the most simple product is the best product. The Flexible Furler has 1/8th the number of parts of competitor systems and is easier to install, operate and maintain. Plus, the Flexible Furler is backed by an unequaled 6-year limited warranty.

A Patented, One Piece, UV Stabilized Luff Extrusion: The CDI luff extrusion is as stiff in torsion as a metal system and yet it can be bent without kinking. There are no joints to fail and it is designed to be winched.

A Built-In Halyard: Eliminates troublesome swivels and halyard wrap, maximizing reliability offshore or close to home.

Reliable Furling: The CDI one-piece urethane furling drum and stainless steel cover keeps the furling line in place. You can accidentally drop your anchor on it and be confident it will keep working.

Easy Installation: Designed to be installed over your existing stay, cutting install time in half.

Low Maintenance: CDI recommends you rinse your bearings with a hose every five years (a five minute procedure). That's it! And you don't have to drop the sail to do it.

User Manuals: Manuals for each CDI furling system can be viewed and/or downloaded from our Document Library.

Save Big: We offer a 7% discount on a new sail when purchasing a CDI furling system.
