I took a bunch of pictures of two of George's submarines that he built. Front view of the experimental human powered K-250. The domed hatch top and front port are covered. Index Back view of the experimental human powered K-250. The domed hatch top is covered.
Large propeller is visible.
The propeller blades were hollow and would fill up with water when submerged. Index Rear port quarter view of the experimental human powered K-250. The domed hatch top is uncovered. The dome is a clear acrylic buble for the operator to look out of. The rudder is visible through the propeller, most of Kitterdge's designs have an electric motor as an active rudder.
