Abstract: A forestay cover has a central tunnel for housing a forestay and two symmetrical side grooves on opposite longitudinal sides. One side groove engagably retains a staysail. The second side groove employs a hoisting handle attached to a halyard of the staysail. A cap on top of the cover provides a curved pathway for the halyard from the one side groove around one side of the central tunnel and into the second side groove. The bottom of the cover is releasably attached to a swivel which rotates the cover about the forestay and thereby furls the staysail. The cover is elastic enough to twist during furling without reaching its elastic limit. The cover is also flexible enough to bend to a radius of less than about one half its length. The swivel rotates about a bearing which is prevented from rotating by a u-shaped bracket. The legs of the u-shaped bracket are secured to the bearing and the curved portion of the u-shaped bracket is linked to a bow fixture, such as a toggle strap.
