Roller furling is a method of furling (i.e. reefing) a yacht's staysail by rolling the sail around a stay. Roller furling is typically used for foresails such as jibs or genoas. [1] A mainsail may also be furled by a similar system, whereby the sail is furled within the mast or around a rotating boom (or around a rotating shaft within a boom).
The headsail of a sloop (where roller furling is not fitted) is often lashed to a guardrail or along a bowsprit. [1] [2]: 104–110 A square sail is furled by gathering it more closely to the yard than is achieved by the buntlines and clewlines and securing it to the yard with gaskets. When bending a sail onto a yard, a square sail is usually ...
Roller reefing rolls or wraps the sail around a wire, foil, or spar to reduce its exposure to the wind. In mainsail furling systems the sail is either wrapped around the boom by a mechanism in the gooseneck or hardware inside the boom winds it around a rotating foil. Furling systems controlled with lines led to the cockpit allow reefing without ...
The common use of roller-furling headsails, or genoas, on modern cruising yachts allows the jib to be reduced in size, but partially-furled sails lack the efficiency of a sail that is actually cut to a smaller size. Accordingly, it is preferable to fly a separate, smaller jib—the solent—instead.
