A water-going vessel having a plurality of water intake turbines extendible and retractable in unison beneath the underside of the vessel. Hull construction pieces preferably comprise a plurality of hollow spheres sandwiched within containment walls, with each sphere in contact with and secured to every adjacent sphere thereto, and further secured to touching containment walls. One preferred turbine has, in sequence, (1) two water intake tunnels having disposed therein rotatable independently controllable tandemly disposed blade groups which spiral water there through in inwardly projecting angles; (2) a mixing chamber wherein water angularly exiting each tunnel collides and proceeds linearly; (3) a venturi constriction passage wherein gas is introduced into water traveling there through; and (4) an exit passage wherein gas is introduced into water traveling there through. A second preferred turbine provides one water intake tunnel having disposed therein blade groups as above-described, introduction of additional water aft of each blade group, and venturi construction and exit passages as above-described. Blade groups are preferably comprised of a plurality of blades attached to a rotor of an alternating current variable frequency submersible electric motor. The turbines operate on a projectile principle and maintain the hull of the vessel above water during cruise.
