Abstract: Personal watercraft having extruded rigid rub rails that can be curved in vertical and horizontal dimensions to provide complex geometries in watercraft. One rub rail has a pair of resilient opposed converging wings extending outwardly from the rub rail to form an open channel along the rub rail length. A first bottom lip can extend inwardly to hug the downwardly facing surface of the top deck. A second lip can curve upward and inward beneath the first inwardly extending bottom lip. The second lip can provide an increased ability to hug sharp horizontally curved corners of the watercraft without wrinkling, for example, the rear corners of the watercraft. The rub rail can be both vertically and horizontally curved in the same region and be affixed to a vertical bond flange. In some personal watercraft, the rub rail is formed of a rigid material having a Shore A hardness of at least about 90.
