ABSTRACT:
A two-speed winch, particularly for nautical applications, comprises a stationary base, a hollow rotary drum supported on the base and a direction-reversible rotary shaft on the base and extending into the drum. The rotary drum may be driven by a first gear train at a first ratio, or by a second gear train at a different second ratio, in dependence upon the direction of rotation of the shaft.
