An inflated roll-stabilizing keel system has a first trough-shaped bladder nd a second trough-shaped bladder attached to the underside of a forward portion of the first trough-shaped bladder. Holes pass through from the first trough-shaped bladder to the second trough-shaped bladder to allow inflation to flow therein. A plurality of shaped bladders are attached successively along and to the first trough-shaped bladder immediately aft of the second trough-shaped bladder. Each shaped bladder has a rectangular base portion attached to the underside of the first trough-shaped bladder. Each shaped bladder tapers downward from its base portion to an open apex. An inflation hole passes through from the first trough-shaped bladder to each of the shaped bladders to allow inflation air to flow therein. Once inflated, adjacent shaped bladders contact one another between the base portion and open apex in an area of contact. Each shaped bladder forms a substantially rectangular shape between its fore and aft areas of contact.

[ What is claimed as new and desired to be secured by Letters Patent of the United States is:] [1.] An inflated roll-stabilizing keel system for a hovercraft, comprising:a supply of pressurized air;a first trough-shaped bladder disposed longitudinally along and attached to the underside of the hovercraft's hull, said first trough-shaped bladder coupled to said supply for inflation thereof via said pressurized air;a second trough-shaped bladder attached to the underside of a forward portion of said first trough-shaped bladder, wherein a plurality of holes pass through from said first trough-shaped bladder to said second trough-shaped bladder to allow said pressurized air to flow therein for inflation thereof;a plurality of shaped bladders attached successively along and to said first trough-shaped bladder immediately aft of said second trough-shaped bladder, each of said plurality of said shaped bladders having a base portion attached to the underside of said first trough-shaped bladder, each of said plurality of shaped bladders tapering downward from said base portion to an open apex, wherein an inflation hole passes through from said first trough-shaped bladder to each of said plurality of shaped bladders to allow said pressurized air to flow therein for inflation thereof so that adjacent ones of said plurality of shaped bladders contact one another between said base portion and said open apex in an area of contact, and wherein each of said plurality of shaped bladders forms a substantially rectangular shape between successive areas of contact; andan aft portion of said plurality of shaped bladders decreasing in height progressively from a forward-most bladder of said aft portion to an aftward-most bladder of said aft portion.
