The present invention relates to a surfboard propelled by human power in surfing. The surfboard includes: an upper board on which a surfer steps, wherein a part thereof is uncovered outside the water surface; a lower board connected to the lower part of the upper board and sunk underneath the water surface; a streamlined body comprising a foam filler generating buoyancy by being filled between the upper board and the lower board; a water jet pump providing propulsion to the surfboard by being embedded in the foam filler; a pedal unit connected to the water jet pump and linearly reciprocating by being and unfolding motions of legs of the server; a handle unit protruding to both sides of the body by passing through the surfboard in the horizontal direction; and a direction changing unit comprising a direction key controlling a propulsion direction by being installed in the rear of the surfboard by being engaged with the handle unit.

    본 발명은 서핑시에 인력으로 추진할 수 있는 서프보드에 관한 것으로, 수면위에 일부가 드러나고 서퍼가 밟고 올라서는 상판, 상판의 아래쪽에 결합되어 수면 아래에 잠기는 하판, 그리고 상판과 하판 사이에 충전되어 부력을 발생하는 발포충전제로 이루어진 유선형 몸체를 가지는 인력추진 서프보드에 있어서, 발포충전제에 매립 내장되어 서프보드에 추진력을 제공하는 워터젯펌프와, 워터젯펌프에 결합되어 서퍼의 다리 굽힘 및 폄운동으로 직선 왕복운동을 하는 페달부, 서프보드의 가로방향으로 관통되어 몸체의 양쪽 측면에 돌출되는 핸들부와, 핸들부에 연동되어 서프보드의 후미에 설치되어 추진방향을 조정하는 방향키로 이루어지는 방향 전환부를 포함한다.
