Highly localized solitary states, driven by means of the spatially uniform, vertical acceleration of a thin fluid layer, are observed to propagate along the 2D surface of a fluid in a highly dissipative regime. Unlike classical solitons, these states propagate at a single constant velocity for given fluid parameters and their existence is dependent on the highly dissipative character of the system. The properties of these states are discussed and examples of bound states and two-state interactions are presented.
