A marine vehicle having enhanced maneuverability, which has a hull at least partially submerged in water. The vehicle has a forward bow, a longitudl axis extending rearwardly from said bow and opposed first and second sides. The first and second sides have respectively a first major opening and a first small opening and a second major opening and a second small opening. The small openings are positioned rearwardly of the first small opening. A major water conducting tunnel extending generally transversely through the hull from the first major opening on the first side of the hull to the second major opening on the said side of the hull. There is a propeller for causing water to flow through the tunnel. A small water conducting system extends between the first small opening on the first side of the hull to the second small opening on the second side of the hull. This system has a first tube that connects the first small opening with the tunnel, and a second tube, which connects the tunnel with the second small opening.
