A personal watercraft has a hull and left and right flow attachment features connected to an underside of the hull near a stern thereof. The left and right flow attachment features are disposed on opposite sides of a longitudinal centerplane of the personal watercraft and are laterally spaced therefrom. For each flow attachment feature of the left and right flow attachment features: the flow attachment feature has a flow surface facing downwardly, the flow surface having a front end and a rear end, the flow surface extending upwardly and rearwardly from the front end to the rear end; and the flow surface is curved in a longitudinal direction of the watercraft such that, in response to water flowing along the flow surface as the personal watercraft moves forwardly on the water, the stern is pulled downwards relative to a bow of the hull.
