The device includes a propeller shroud and a aft fairing each having a layer of acoustic material to reduce sound generated by the rotating propeller. The construction of the device also provides increased maneuverability, stopping and reverse to pre-existing as well new air-boats by providing operator controlled vector thrusts.
