A model of the Dornier racing seaplane which was projected for competition in the 1929 Schneider Trophy contest.

A German Schneider Trophy Challenger? This sketch shows a model exhibited by Dornier, and representing a design for a racing seaplane. The two engines are intended to be of 1,000 h.p. each, and the long floats, of unusual cross-section, extend aft to carry the tail. The inset shows the section of the floats in the neighbourhood of the single step.
