Aquaplane Debut

Model Diane Dorsey demonstrates the new motorizedAquaplane, which was put on display for the first time at the Inventor's Convention in Los Angeles, Calif., Dec. 5, 1938. The craft is powered by a four horsepower motor, which inventor Raymond Strawn says will function even when submerged, and carries two gallons of gasoline, enough for a 25 mile cruise.
