BOAT RUNS ON ROLLING DRUMS (Dec, 1932)
BOAT RUNS ON ROLLING DRUMS
A boat that runs along the surface of the water on drums was given a trial recently on the Hackensack River, near Newark, N. J. Five specially-designed white steel drums, having indentations like the treads on tires to increase their grip upon the water, support the craft. The free-rolling drums reduce the resistance of the water and are expected to permit high speeds with low power. An airplane engine and propeller drive the boat, which can be run up on the shore. During the experimental runs, the body, which will accommodate several passengers, was not attached to the framework.
