  • Roller furling mechanism
    Patent number: 4080917
    Abstract: The jib furling mechanism is located beneath the junction of the bridle wires which hold the forestay to permit the forward portion of the foot of the jib to extend to the bridle junction and increase jib area. The bridle wires are joined by a structural link integrally formed with the housing for the furling mechanism. This housing telescopically receives a forestay adjuster for adjusting mast rake. The jib may be lowered without removing the forestay, or it may be furled about the forestay using the furling mechanism.
