A genoa furling system allows the foresail to be furled around the luff wire to prevent the sail flogging when not in use.

The addition of an Aero spar prevents the luff wire being deformed by the twisting action of the furling drum.

The Aero Luff Spar can be attached to any of the readily available furling systems to make the furling process more efficient, and upgrade it to a reefing system.

The only recommended types of furling system are those having an enclosed drum for the furling line.

Using an Aero spar as a genoa reefing system allows the size of the genoa to be adjusted to the strength of the wind, or the size and/or strength of the crew.

The sail is secured by means of a unique plastic clamp to avoid the bulge in the luff of the genoa caused when a cringle is furled around the spar.

The luff wire passes through the hollow centre of the spar, with the swaged solid eye terminals at either end of the wire attached to the bow fitting and genoa halyard.

The Top Swivel and Bottom Drum rotate on acetal bearings around the swaged solid eye terminals at either end of the luff wire.

The luff wire and swaged solid eye terminals take all the load that is applied when tensioning the genoa halyard.

With no loading applied to the drum and top swivel, (as is the case with all the separately bought systems), the spar is free to turn with virtually no frictional resistance.

The lightweight (less than 0.5Kg), and compact (8mm diameter) spar provides an efficient aerodynamic entry shape for the genoa.

The Aero Furling Spar is supplied complete with disc spacer to keep the forestay away from genoa luff.

The Aero Furling Spar provides an efficient way of furling a genoa to save it from flogging - after rigging, launching, on the water, approaching landing, or in the dinghy park - without any loss of performance when racing.

The low profile drum raises the foot of the genoa only 15mm higher than a standard luff wire thimble fitting.

A coupling can be used to raise the base of the furling drum sufficiently for it to be pivoted about the clevis pin, saving the need to detach the spar from the bow fitting when lowering the sail - which is necessary without this coupling.

When furling/reefing the sail in strong winds, it is advisable to sail off the wind to take the power out of the genoa for the few seconds that it takes to furl the genoa to the required size.

The Aero Spar, whilst having the flexibility to bend round into a wide U shape if held at either end, is a rigid material, and will break if bent round too far, particularly should the spar be left attached to the bow fitting and a point loading is applied around the middle of the spar to pull the top down under the spreaders.

It is recommended that the furling drum is (manually) turned back a few turns after bringing the boat ashore, to ensure the genoa luff is not left tightly wrapped around the spar in the dinghy park.
