Abstract

An improved top down furling system includes one or more improved components. A lower rotary drive unit with a rotary tack swivel rotates against a fixed portion of the furler, or is configured to permit routing of the tack line below the unit. The system may include an anti-torsion cable constructed in a manner so as to be able to transmit torque without excessive tension applied to the cable. The system also may include an end terminal of the anti-torsion cable having a quick side mount or bayonet type connection to the rotary drive unit.

Claims (4)

1. A release for use in a top-down furling sail system having an anti-torsion cable, a terminal receiving device for connection to the anti-torsion cable, and an end terminal on at least one end of the anti-torsion cable, the release wherein:

the end terminal has outwardly extending lips, and

the terminal receiving device has a receptacle for receiving the end terminal, the receptacle having undercuts to receive and releasably hold the end terminal lips so as to provide a tensiley and torsionally secure connection between the anti-torsion cable and the terminal receiving device.

2. A release for use in a top-down furling sail system according to claim 1 wherein the terminal receiving device further includes a spring loaded button adjacent the end terminal receiving receptacle for releasably retaining the end terminal in the terminal receiving receptacle.
