The present invention relates to a human-powered boat that a user can relatively easily operate with his/her athletic ability even though the boat powered by using human power is in the form of a shipwith a large resistance to propulsion, and the human-powered boat is equipped with a propulsion apparatus that imitates the tail fin of a fish. The propulsion apparatus, in which an oscillating foiltechnology is applied to an "L-shaped oar", enables a rider to perform forward-facing rowing and can easily change a direction and prevent damage due to a collision with an underwater obstacle. Typically, the human-powered boat of the present invention has the following three limitations in order to maximize brevity while maintaining propulsion efficiency, compared with a prior art in the same technical field: First, a rider has a specific limitation in tilting the propulsion apparatus through an up-down motion of his/her arm. Second, the foil of the propulsion apparatus does not make contactwith the longitudinal center line of a ship hull in a predetermined range of motion. Third, the propulsion apparatus has a predetermined level of limitation in generating a propulsive force below thesubmerged portion of a ship hull.
