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.

First claim

What is claimed is:

1. A watercraft, comprising:
a plastic body having a unitary, single-piece construction, the plastic body having a substantially hollow interior, and the plastic body including a parting line; and
a solid compression molded element that is integral with the plastic body, and the solid compression molded element is configured and arranged such that the parting line is not part of the solid compression molded element, and the solid compression molded element is a permanent part of the watercraft.

2. The watercraft as recited in claim 1 , wherein the solid compression molded element is completely disposed within an envelope defined by outermost surfaces and outermost edges of the watercraft.

3. The watercraft as recited in claim 1 , wherein the solid compression molded element lies in a plane that is non-parallel with respect to a plane in which part or all of the parting line of the watercraft lies.

4. The watercraft as recited in claim 1 , wherein the solid compression molded element lies in a plane that is approximately perpendicular with respect to a plane in which part or all of the parting line of the watercraft lies.

5. The watercraft as recited in claim 1 , wherein the solid compression molded element includes a depression and/or a hole.

6. The watercraft as recited in claim 1 , further comprising a recess located proximate the solid compression molded element, and the recess is integral with the plastic body.

7. The watercraft as recited in claim 1 , further comprising a first recess and a second recess, wherein the first recess and the second recess are located proximate the solid compression molded element, and the first recess and the second recess are integral with the plastic body.

8. The watercraft as recited in claim 1 , further comprising a first recess and a second recess, wherein the first recess and the second recess are located proximate the solid compression molded element, and the first recess and the second recess are positioned opposite each other and do not communicate with each other, and the first recess and second recess are integral with the plastic body.

9. The watercraft as recited in claim 1 , further comprising a first recess and a second recess, each of which is integral with the plastic body, wherein the first recess and the second recess are disposed proximate opposite respective sides of the solid compression molded element, and the first recess and the second recess are substantially mirror images of each other.

10. The watercraft as recited in claim 1 , further comprising a recess located proximate the solid compression molded element, where the recess is integral with the plastic body, and the recess has a concave configuration located on an exterior of the watercraft.

11. The structure as recited in claim 1 , further comprising a recess located proximate the solid compression molded element, where the recess is integral with the plastic body, and the recess has a convex configuration within the substantially hollow interior of the structure.

12. The structure as recited in claim 1 , further comprising a first recess and a second recess, each of which is located proximate the solid compression molded element, where the first recess and the second recess are integral with the plastic body, and both the first recess and the second recess have a convex configuration within the substantially hollow interior of the structure, and both the first recess and the second recess have a concave configuration located on an exterior of the structure.

13. The watercraft as recited in claim 1 , wherein the watercraft comprises a kayak.

14. The watercraft as recited in claim 1 , wherein the watercraft comprises a paddleboard.

15. The watercraft as recited in claim 1 , wherein the plastic body comprises a hull.

16. The watercraft as recited in claim 1 , further comprising one or more tack-offs that are integral with the plastic body.

17. The watercraft as recited in claim 1 , wherein the entire solid compression molded element is set back from an edge of the watercraft.

18. The watercraft as recited in claim 1 , wherein the solid compression molded element does not contact the parting line.

19. The watercraft as recited in claim 1 , wherein the parting line extends a majority of a length of the watercraft.

20. The watercraft as recited in claim 1 , further comprising another solid compression molded element that is integral with the plastic body.
