ABSTRACT:
A submarine hull which has a half wing-like sail which projects vertically upwards, is provided with a keel-wing that also is half wing-like, but projects vertically downwards. By preference the keel-wing has a lower end plate and its main portion is trailed by two slotted flaps which can be pivotally moved in both directions about respective vertical axes in coordination with movement of the rudder of the submarine. If needed for permitting operation in shallow water or with the hull close to the bottom, the wing can be made to retract. The keel-wing not only counters the sail's rolling movement and keeps the hull upright, but also adds a side force to assist in tightening the turn.
