A paravane for a marine seismic survey system includes a float and at least one diverter operatively coupled to the float. The diverter is configured to redirect flow of water past the paravane with respect to a direction of motion of the paravane through water. The paravane also includes a steering device. The steering device is configured to controllably redirect the flow of water so as to control an amount of lateral force generated by the paravane.
