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 ...
On cruising sailboats, a modestly sized asymmetrical spinnaker can be tacked to a centerline bow pulpit, anchor roller or a furled headsail, and can be known by other names, like "cruising chute" or a gennaker. In this duty, it is often paired with a Spinnaker chute or "sock" for simpler or short-handed setting and retrieving.
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.
Three years later, in 1971, Macalpine-Downie and Gibbs finished the design on the Mutineer 15. The Mutineer and Buccaneer are very similar in basic design, and include many of the same features. At the time it was designed, the Mutineer had several innovative features, including the roller furling jib, spinnaker rigging, and a foredeck launcher ...
It is universally used for parcels, rolls and bundles. At sea it is always employed in reefing and furling sails and stopping clothes for drying. But under no circumstances should it ever be tied as a bend, for if tied with two ends of unequal size, or if one end is stiffer or smoother than the other, the knot is almost bound to spill. Except ...
Bolt ropes are sewn onto the edges of the sail to reinforce them, or to fix the sail into a groove in the boom, in the mast, or in the luff foil of a roller-furling jib. [15] Leech lines are found on mainsails and large jibs to tighten the leech and prevent fluttering. They run through a sleeve on the leech from the head to the clew, where ...
