Claims

[Scope of utility model registration request]

A notch is provided at the bottom of the rear end of the hull, and within this notch, a propulsion water jet jet pipe with its outer surface exposed in the open water is arranged so as to be rotatable to the left and right. A water jet propulsion vessel, characterized in that an inner wall is formed to widen toward the rear to allow left and right rotation of the water jet jet pipe.
