A body surfing board includes a flexible hull having a lower surface, an upper surface adapted to receive a swimmer, and a nose section defining a forward end of the hull. A tail section including a keel extends downwardly from the lower surface of the hull. A pair of fins extend downwardly from the hull along opposite lateral edges thereof. The fins are each pivotable along their respective attachment to the hull, inwardly and outwardly with respect to one another. A plurality of slits extend between the pair of fins for translating the force of a water wave into forward movement of the body surfing board. In one embodiment, a plurality of ribs fixed to the lower surface of the hull define the slits. In another embodiment, a plurality of ribs are positioned within the nose section of the hull to open and close the slits in response to movement of the fins. In still another embodiment, the slits are incorporated into a diaphragm member. A pair of pommels are fixed to the hull to support the backs of the swimmer\s arms. The tail section may include a tail fin attached to the keel within one of a plurality of channels. The fins may include sleeves or external hand grips.
