ABSTRACT:
A submersible marine vehicle, operable both upon and beneath water, includes a fluid-tight hull elongated along a longitudinal axis corresponding to an intended direction of travel of the vehicle, the hull having integral gripping elements and velocity controls proximal to each of the gripping elements, the hull further including internally energy storage elements for power control and transfer within an air space in the hull, the air space also defining a buoyancy characteristic of the vehicle, the hull and the hand gripping elements defining a total longitudinal dimension co-linearly to the longitudinal axis of the hull. The vehicle also includes a single circumferentially integral propeller shroud depending integrally downwardly from a lower surface of the hull along an axis transverse to the axis of the hull. Further included is a propeller and motor, the propeller mounted within the shroud parallel to the axis of the hull, the propeller having a diameter approximately equal to the interior diameter of the shroud, the propeller and motor defining an aggregate longitudinal dimension parallel to the axis of the hull, the aggregate dimension being generally equal to the aggregate longitudinal dimension of the hull and handle gripping elements, the motor in electrical communication with the power transfer elements within the hull and subject to actuation by the velocity control elements.
