In order to stabilize the aircraft in an upright position when it was floating on the water, the Boeing B-314, the Martin 130 China Clipper, and the Dornier DO-X used "sponsons", short stub-wings extending sideways from the fuselage at the waterline. Other flying boats of similar size, vintage and performance, such as the Short Empire and Sunderland, used stabilizing floats at or near the wing tips for the same purpose, and Martin used tip floats on their later Mars flying boat. What are the pros and cons of the two devices, and what considerations go into a designer selecting one or the other? Thank you in anticipation, Peter Wezeman, anti-social Darwinist "Carpe Cyprinidae"
