PROBLEM TO BE SOLVED: To provide a marine vessel improved in propulsion performance and steering performance.SOLUTION: A water current forming path 3 is formed on a ship bottom 2. A propeller 6 is arranged in the water current forming path 3 and a steering 8 is arranged at the back of the propeller 6. The movable side of the steering 8 is arranged toward the stem direction. As a result, a rapid water current is generated in the water current forming path 3 by action of the propeller 6, to thereby increase the thrust force and enhance the propulsion performance, and the rapid water flow rate in the water current forming path 3 is applied on the steering 8 to increase the steering performance. In a marine vessel 1 with an outboard motor, a vertical groove is formed in a stern 4, so that the outboard motor can be lowered and exchanged in the water current forming path 3 through the vertical groove, and a countermeasure in the event of failure can be simply performed by oneself, and a boat can be pulled out onto a sand beach or can be pulled back out of water as it is, because a propeller portion of the outboard motor is set back from the ship bottom surface. |
