Abstract:
A winch has a color area or other indicium that indicates whether an elongate member extending from winch spool is or is not tensioned. The winch includes a biasing member between a winch drive system and the spool that allows only limited rotation of the spool relative to the drive system. Movement of the drive system relative to the winch spool causes the indicium to signal that the elongate member is under tension.
