Abstract: In one example, a method includes positioning, within a mold, a device with a movable element that defines a portion of a volume, and the volume is contained within the mold, as part of a molding process, at least partly defining a molded watercraft by introducing plastic into the mold, disposing the plastic about the movable element, and with the movable element, excluding the plastic from the portion of the volume that is defined by the movable element so as to define a recess and an undercut that are integral with the watercraft and extend lengthwise with respect to a centerline of the watercraft, and the recess and undercut are integral, and communicate, with each other.

Abstract: In one example, a watercraft includes a hull that defines a recessed portion, and the hull is a unified, single-piece, structure. The watercraft further includes a self-draining scupper with a passageway that is integral with the hull and communicates with the recessed portion, the passageway extending from the recessed portion through an exterior surface of the hull. The self-draining scupper further includes a stopper disposed in the passageway, and a flow plate that helps to confine the stopper in the passageway.

Abstract: In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

Abstract: In one example, a method includes positioning, within a mold, a device with a movable element that defines a portion of a volume, and the volume is contained within the mold, as part of a molding process, at least partly defining a molded watercraft by introducing plastic into the mold, disposing the plastic about the movable element, and with the movable element, excluding the plastic from the portion of the volume that is defined by the movable element so as to define a recess and an undercut that are integral with the watercraft and extend lengthwise with respect to a centerline of the watercraft, and the recess and undercut are integral, and communicate, with each other.
