A swivel device with rotation damping, adapted to rotationally couple a hoist cable to a hoist hook, the device including: a first disc fixedly mounted on a central axle and adapted to be operationally coupled to a distal end of the cable by a non-rotating coupling; a second disc rotationally mounted on said central axle and spaced apart from said first disc, said second disc adapted to be operationally coupled to the hoist hook by a non-rotating coupling; a first set of magnets mounted on said first disc; and a second set of magnets mounted on said second disc, magnetic fields of said first set of magnets interacting with magnetic fields of said second set of magnets to damp rotation of said second disc about said central axle.
