A watercraft is disclosed that includes a hull having port and starboard sides and a propulsion system that generates a stream of pressurized water through a nozzle. A helm operatively connects to the nozzle, whereby turning the helm turns the nozzle. At least one rudder connects to either or both of the port or starboard sides. The rudder is capable of pivoting inwardly and outwardly and can also be moved upwardly and downwardly with respect to the side to which it is connected. The rudder is located a certain distance from the respective side of the hull, which allows the rudder to utilize its inner and outer surfaces to assist in steering the watercraft by deflecting water flowing thereacross. Also, a linking element can connect the nozzle to the rudder. An off-power steering system is also disclosed.
