Furling Headsail

Furling Headsail

Furling systems have been around a long time now, and work so well we kind of take them for granted.

From the early days the genoa was a perfect sail to be rolled away - it had a long enough foot that the sail remained balanced even when deeply furled, and the sheet lead, whilst not ideal, did not need moving too much.

The problems that became clear were that the sail became fuller and fuller as the sail was reefed, and the boats ability to go to windward was compromised.

Elvstrøm Sails came up with the foam insert, running all the way up the luff and positioned individually to prevent permanent deformation. This created a differential diameter in the headfoil, which in turn furled the middle of the sail away faster than the corners, proving enormously successful. Today we still use a reefing compensator, either in the form of e-foam or e-flex. Also available for furling jibs.

UV protection in the leech and foot ensures a much longer lifetime and is recommended for furling headsails. Test show that UV-treated cloth has a 25-30% longer lifetime than untreated cloth.

Furling jibs may have battens to ensure that the leech of the jib overlaps the main as much as possible. Without battens the leech would have to be cut with a hollow, and this overlap would  not exist. With swept-back spreaders this „overlap" should be possible.

This is not at all about area - its the MOST important part of the jib, and its missing. It is an aerodynamic disaster.

Using leech battens being orientated to be parallel to the forestay („vertical") allows the sail to furl well. And makes a sail which is a little larger, and most importantly, a much better shaped aerodynamic „wing."

Available in woven polyester, DC laminates or EPEX.

We recommend covering the sail with a FurlCover or removing the sail when your boat is in the marina.
