A personal watercraft designed to advance suitably in a forward direction, to prevent an influence of side waves, and to incline to the turning center side when being steered by an operator from a forward direction to a turned direction. The personal watercraft includes a keel provided at a middle portion in the widthwise direction of the bottom of the body and extending from the bow to the stern. The keel is formed in an arc in the widthwise direction of the body. The keel is configured such that, at the rear half portion of the body, the center of the arc of the keel substantially coincides with the position G of the center of gravity of the body. On the other hand, at the front half portion of the body, the radius R2 of the arc of the keel gradually decreases in the forward direction.
