Watercraft hull

1. A watercraft hull comprising:

a hull body defining a bow, a transom, and a longitudinal centerline extending from the bow to the transom along a center of the hull body, the hull body having an inner surface and an outer surface;

at least one port rib extending at an angle to the longitudinal centerline on the inner surface, the at least one port rib having a first portion disposed on a port side of the longitudinal centerline and a second portion disposed on a starboard side of the longitudinal centerline, the first portion being longer than the second portion; and

at least one starboard rib extending at an angle to the longitudinal centerline on the inner surface, the at least one starboard rib having a first portion disposed on the starboard side of the longitudinal centerline and a second portion disposed on the port side of the longitudinal centerline, the first portion being longer than the second portion,

one of the at least one port rib and the at least one starboard rib being disposed at least in part forwardly of the other of the at least one port rib and the at least one starboard rib.

2. The hull of claim 1 , wherein the at least one port rib is a plurality of port ribs and the at least one starboard rib is a plurality of starboard ribs; and

wherein the plurality of port ribs and the plurality of starboard ribs are disposed in an alternating arrangement along a length of the hull body.

3. The hull of claim 2 , further comprising a secondary rib extending at an angle to the longitudinal centerline on the inner surface, the secondary rib being disposed completely on one side of the longitudinal centerline.

4. The hull of claim 2 , wherein the plurality of port ribs and the plurality of starboard ribs extend generally perpendicularly to the longitudinal centerline.

5. The hull of claim 2 , wherein at least one of the plurality of port ribs and the plurality of starboard ribs has an enlarged portion adapted to receive a fastener.

6. The hull of claim 5 , further comprising a threaded insert disposed in the enlarged portion.

7. The hull of claim 1 , wherein the hull body defines a port side wall and a starboard side wall;

wherein at least part of the first portion of the at least one port rib extends along the port side wall; and

wherein at least part of the first portion of the at least one starboard rib extends along the starboard side wall.

8. The hull of claim 1 , wherein the hull body, the at least one port rib, and the at least one starboard rib are integrally formed.

9. The hull of claim 8 , wherein the hull body, the at least one port rib, and the at least one starboard rib are made of a mixture of cut glass fibers and urethane resin.

10. The hull of claim 1 , wherein a height of at least one port rib is greater than a width of the at least one port rib; and

wherein a height of at least one starboard rib is greater than a width of the at least one starboard rib.

11. The hull of claim 1 , wherein a width of the at least one port rib is at least 1.5 times a thickness of the hull body at a position adjacent the at least one port rib; and

wherein a width of the at least one starboard rib is at least 1.5 times a thickness of the hull body at a position adjacent the at least one starboard rib.

12. A watercraft hull comprising:

a hull body defining a bow, a transom, and a longitudinal centerline extending from the bow to the transom along a center of the hull body, the hull body having an inner surface and an outer surface;

at least one first rib extending at an angle to the longitudinal centerline on the inner surface, the at least one first rib being disposed completely on one of a port side and a starboard side of the longitudinal centerline; and

at least one second rib extending at an angle to the longitudinal centerline on the inner surface, the at least one second rib having a first portion disposed on the other of the port side and the starboard side of the longitudinal centerline and a second portion disposed on the one of the port side and the starboard side of the longitudinal centerline, the first portion being longer than the second portion.

13. The hull of claim 12 , wherein the at least one first rib is a plurality of first ribs and the at least one second rib is a plurality of second ribs.

14. The hull of claim 12 , wherein at least one of the at least one first rib and the at least one second rib has an enlarged portion adapted to receive a fastener.

15. The hull of claim 14 , further comprising a threaded insert disposed in the enlarged portion.

16. The hull of claim 12 , wherein a height of at least one first rib is greater than a width of the at least one first rib; and

wherein a height of at least one second rib is greater than a width of the at least one second rib.

17. The hull of claim 12 , wherein a width of the at least one first rib is at least 1.5 times a thickness of the hull body at a position adjacent the at least one first rib; and

wherein a width of the at least one second rib is at least 1.5 times a thickness of the hull body at a position adjacent the at least one second rib.

18. The hull of claim 12 , wherein the at least one first rib and the at least one second rib extend generally perpendicularly to the longitudinal centerline.

19. The hull of claim 12 , further comprising:

at least one third rib extending at an angle to the longitudinal centerline on the inner surface, the at least one third rib being disposed completely on the other of the port side and the starboard side of the longitudinal centerline; and

at least one fourth rib extending at an angle to the longitudinal centerline on the inner surface, the at least one fourth rib having a first portion disposed on the one of the port side and the starboard side of the longitudinal centerline and a second portion disposed on the other of the port side and the starboard side of the longitudinal centerline, the first portion being longer than the second portion.
