Silent Runner II is a two man submarine basically built around a discarded jet aircraft drop tank. Air is supplied from a standard 72 cu. ft. scuba tank with a single hose regulator. The propulsion units are two electric trolling motors, and current is supplied from three 12-volt automotive or deep cycle marine batteries. The sub's maximum running time on a full charge is about 4 hours. The Skipper of the sub rides inside the enclosed cabin in an air pocket. His diving buddy, wearing full scuba gear, rides outside in a forward lookout position. Negative buoyancy is achieved by operating a variable buoyancy valve. The two motors are tilted up or down to achieve thrust in the direction desired. Turns are made by cutting one motor or the other. You can reverse one motor and run the other forward for an even sharper turn. The sub was featured in Popular Mechanics Magazine and on the cover. It has also been featured on The David Frost Show on TV. |
