摘要： This invention relates to a marine winch for hauling sheets, lifts, halyards and analogous tackle. The invention provides a winch having a circular main casing adapted to be fixed to a deck, a winch drum rotatable about the axis of an upper generally cylindrical turret of said casing, first unidirectional clutch means operatively located between the drum and the turret and permitting relative rotation between the drum and the turret in one direction only; a circular sub-casing having an upper sleeve portion extending through and coaxial with said turret, said sub-casing being rotatable about the axis of the turret, second unidirectional clutch means operatively located between the sleeve and the drum and permitting relative rotation between said sleeve and said from in one direction of rotation only, an operating spindle located axially of the turret and rotatable relative thereto, gearing adapted to transmit drive from said operating spindle to a flared circular lower part of said rotatable sub-casing, said gearing including two output gear wheels engaging diametrally opposite regions of a toothed ring formed within said flared circular lower portion of said rotatable sub-casing. Preferably the gearing is arranged to drive the output gear wheels in two ratios of say 3.5 : 1 and 11 : 1 selectable on rotating the operating spindle in opposite directions.
