<p>The present invention relates to a steering device for a waterjet propelled boat, which can easily switch the direction of a hull with a simple structure, and to a waterjet propelled boat including the same. The steering device for a waterjet propelled boat can adjust the direction of a sea route of the hull by being installed in a waterjet propellant which forms waterjet and discharges the waterjet to the nozzle type rear unit thereof. The steering device for a waterjet propelled boat comprises: a double flow path casing installed in the back side of the nozzle type rear unit and including a first discharge flow path which guides waterjet in order to be discharged toward the back side of a hull, and a second discharge flow path which is formed in the lower part of the first discharge flow path in order to guide the waterjet to be discharged toward the lower part of the first discharge flow path; and a discharge guide unit which switches the direction of a sea route of the hull by guiding the waterjet, discharged to the lower part of the first discharge flow path through the second discharge flow path, in order to be discharged toward one side of the bottom of the hull under the water through the bottom of the hull.</p> |
