A water craft includes two parallel, spaced-apart pontoon hulls, and a superstructure bridging between the pontoon hulls. A propeller is operatively connected to foot pedals so that the propeller can be rotated to drive the craft. The propeller is supported between the two pontoon hulls, in such a way as to allow the propeller to shift laterally across the spacing between the pontoon hulls. Two rudders are provided aft of the propeller, and a steering arrangement simultaneously controls the angulation of the rudders and shifts the lateral position of the propeller toward the pontoon hull which would describe the outside arc for the turning maneuver in the desired direction.
