ABSTRACT:
An underwater apparatus includes a seat portion and a pedestal extending from the front of the seat portion. A helmet is attached to the remote end of the pedestal and forms a compartment with an opening toward the seat portion. At least a part of the helmet is transparent. A tank of compressed air is attached to the apparatus and supplies air to the compartment. A diver straddles the seat portion and the diver's head extends through the opening into the compartment in order to breath air therein. In the preferred embodiment, a motorized propulsion system is operatively coupled to either the seat portion or the helmet for propelling the vessel underwater.
