From your cockpit in a matter of minutes you can furl or reef your jib, genoa or staysail with ease—a great boon for small boat owners since the smaller the boat, the more difficult the foredeck work. The CDI Flexible Furler one piece, PVC single groove luff extrusion is stiff in torsion for better reefing and furling but flexible in other directions for easy handling when raising and lowering the mast — a great choice for trailerables and other boats where the mast is frequently raised and lowered. There are no joints to bend or break as with non-flexing metal extrusions which must be made in sections for shipment purposes. The CDI flexible furler also features an internal halyard which makes it possible to raise and lower sails while underway. This halyard eliminates the halyard loads from the bearings making reefing easier. It also eliminates halyard wraps and those troublesome halyard swivels. The tack fitting is a simple lashing that won't fall overboard (unlike a pin or shackle). A durable one-piece furling drum keeps the furling line in place. The CDI Flexible Furler — a very durable system for boats that are trailered. Great where the mast is stepped frequently — forestay comes down with extrusion in place!
