Abstract
A sailboat winch basically includes a support, a winch drum, a drive shaft and a transmission mechanism. The support is mounted to a sailboat. The winch drum is rotatable with respect to the support. The drive shaft is rotatable with respect to the support and the winch drum. The transmission mechanism is operatively disposed between the drive shaft and the winch drum to transmit rotation from the drive shaft to the winch drum in a single output rotational direction. The transmission mechanism increases an output rotational speed of the winch drum with respect to an input rotational speed of the drive shaft as the drive shaft rotates in a first rotational direction. The transmission mechanism also decreases the output rotational speed of the winch drum with respect to the input rotational speed of the drive shaft as the drive shaft rotates in a second rotational direction.
