Rudder device for a hydrojet vessel

A rudder device for a hydrojet vessel, the hydrojet vessel having a hull including a stern, a port side and a starboard side, a vertical pivot pivotably coupling a hydrojet to the stern for producing a directional thrust and propelling the hydrojet vessel through a body of water, the rudder device comprising:

• a mounting plate having a front edge, a rear edge, a primary side and a secondary side;
• a primary rudder coupled to said primary side of said mounting plate;
• a secondary rudder coupled to said secondary side of said mounting plate;
• said mounting plate, said primary rudder and said secondary rudder defining an elongated general inverted U shape rudder coupled to the hydrojet for providing steerage as the hydrojet vessel is displaced through the water;
• and
• said mounting plate defining a downward deflection slope for providing an ascending force against said mounting plate by the body of water during forward displacement of the vessel and creating an upward force against the stern of the vessel.
