A marine rail lift has a lift deck assembly configured to receive a watercraft thereupon and move between a raised position and a lowered position relative to a parent dock. A plurality of track rails connected to the side walls of a berth of the parent dock define a movement path of the lift deck assembly between the raised position and the lowered position. A plurality of retractable track pins engage the lift deck assembly to the track rails. A lift control system is operatively engaged with the lift deck assembly and configured to displace the lift deck assembly between the raised position and the lowered position. The lift control system manages the volume of air contained within one or more lift tanks of the lift deck assembly to control displacement of the lift deck assembly through buoyant force.
