A latching winch comprises a spool having a drive pin offset from the axis and extending out from one side. A drive/latch assembly comprises a drive plate formed with an opening coaxial with the spool and carrying in the opening a bushing having internal crank-engaging opening and a lateral drive lug spaced from the bushing. A pair of mirror-image pawl plates are stacked sidewise each having against the drive plate, the pawl plates each having an aperture in one end pivotally receiving the spool drive pin, a central opening loosely receiving the bushing and pawl detents extending outward, the pawl plates having projections, on the other end, the projections being disposed on opposite sides of and being adapted to be selectively engaged by the drive lug on the drive plate. A spring biases the pawl plates with their pawl detents outward. A stationary ring-gear-like cam is concentric with the axis and surrounds the drive and pawl plates, the cam having inwardly facing peaks and valleys, the cam and detents comprising the latch.
