The Sea Turtle was an amphibious motor car designed by the volcanologist Dr Thomas A. Jaggar, who led an expedition to the Aleutian Islands with it. In 1945 Popular Mechanics called it the "grandpappy of the Duck", printing a National Geographic photograph of Jaggar sitting beside the vehicle.

Design

Popular Science described it as a boat built onto a Ford chassis. On land it ran as a car; for use afloat, paddle wheels were fitted to the rear wheels and drove the craft forward, while the disc-shaped front wheels served as rudders.

The sources disagree on its size: Popular Science gives the boat as 16 feet (about 4.9 m) long, while a National Geographic caption speaks of a 21-foot (about 6.4 m) steel craft. It is possible that more than one version existed.
