Abstract: In one example, a method includes positioning a tool in a mold, forming a parison of melted plastic, closing the mold around the parison and tool such that part of the tool is positioned between a portion of the mold and the parison, creating a blow molded structure by inflating the parison so that the melted plastic comes into contact with an interior portion of the mold and into contact with the tool, and after the mold is closed, operating the tool to form an integral compression molded element within the mold, and a parting line formed by the mold in the blow molded structure forms no part of the integral compression molded element.

Abstract: In one example, a watercraft includes a hull in the form of a unitary, single-piece structure that is substantially hollow, and made of plastic. A grip is provided that is integral with the hull and includes a recess that is formed in a skin of the hull and is integral with the hull, and the grip also includes an undercut that is formed in the skin of the hull proximate an edge of the recess. The undercut is integral with the hull and communicates with the recess.

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 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.
