A manual marine winch includes a safety knockout override preventing release of winch tension without the handle in stowed position. The winch includes a housing; a rotating drum on the housing; a winch line on the drum; a control for spooling and un-spooling the winch line on the drum, wherein the control includes a handle for selectively tensioning the drum and moveable between a position engaged with the drum and a disengaged stowed position; a tension holding mechanism on the housing comprising a ratchet gear coupled to the drum, a pawl selectively engaged with the ratchet gear, and a knockout configures to selectively disengage the pawl from the gear to allow for release of winch tension; and a safety knockout override coupled to the housing and selectively engaged by the handle and configured to prevent release of winch tension when the handle is not in the stowed position.

A manual winch with dual locking dogs is designed to be easily retrofitted into existing winches. The design of the winch includes a housing supporting a rotatable drum upon which the cable is reeved. A pair of gears are attached to the drum with locking dogs that may be independently engaged with each gear, wherein the drum is prevented from unwinding with at least one locking dog engaged with a respective gear.

A manual winch includes a housing supporting a rotatable reel, a ratchet assembly coupled to the reel movable between an engaged and disengaged position, and a load releasing system for moving the ratchet assembly system to a disengaged position. The ratchet assembly includes a rotatable ratchet gear which is adapted to be engaged by a pivotable locking pawl. The locking pawl is pivotable into and out of engagement with the ratchet gear for moving the ratchet assembly between the engaged and disengaged position. The locking pawl is mounted on a movable base which secures the locking pawl to the housing. The load releasing system includes a linear actuator for moving the relative position of the base relative to the ratchet gear and the housing, and a separate brake for holding the reel and ratchet gear in position under a load.
