Protect a Jib's Head from sunburn
Most all roller-furling headsails have fabric strips sewn to the leech and foot to protect the furled sail from ultraviolet radiation (UV). At the head of the sail, though, the webbing loop by which the sail is shackled to the upper swivel remains exposed and subject to U.V. degradation. That's where the JibCap comes in.
The JibCap is a wrap made of Sunbrella to cover and protect the webbing loop. Installation is straightforward: a small flap is placed through the shackle, and larger flaps from both sides wrap completely around the head and secure with Velcro. The webbing loop on our genoa is secured to the a stainless ring that attaches to the shackle, so we placed the upper flap through the ring. The instructions say to wrap the head of the sail above the luff tape, but if the luff tap extends too close to the head to allow this, the JibCap may be wrapped completely around the foil. That's how we installed it and the JibCap appears to work as promised. We've raised the sail and furled it with no problems, and our webbing loop is now protected.
