The steamer had a flat bottom 73 and was provided for about two thirds or three quarters of its whole length, measured from the stern forward, with four or five very shallow strips (one can hardly call them keels) running longitudinally, and closed at their forward ends. Into each of the channels thus made there was injected air by an air pump, under a slight pressure, only just sufficient to overcome the "head" water, and thus air travelled along the channels and escaped at the stern. In order to keep down the species of ebullition, there was a projecting work at the stern which earned for the boat the name of "Smoothing Iron".
They could be arranged in three sets, or in one set continuous along the keel. In 1907 Thompson proposed a development of this form of craft, having 'curved aquaplanes of approximately catenary shape in a transverse direction, attached to the sides of the vessel, with additional angular or curved fins, also attached to the sides, but extending outwards'. A true American pioneer was William M. Meacham, who, on July 29,1897, at Chicago, Illinois, towed a boat, fitted with blades, until the hull rose clear.
