BACKGROUND OF THE INVENTION
Boat hulls may have stiffeners to keep shape of various portions, such as the bottom or hull of the boat.
The relevant art method of making the bottom of boats is clamping the bottom of the hull to a jig, and then welding stiffeners to the inside bottom. Once the jig is released from the bottom, the bottom stresses and strains created by the weld cause deformations in the bottom, which makes each bottom different, which reduces shape and structural consistency.
What is needed is a method of assembling a bottom of a boat of bottom of a hull to create a consistent structure, with consistent tension and compression forces throughout. What is also needed is a method of using ribs to give and provide the shape to a bottom, and to provide strength, without using jigs. What is also needed is a method to create or provide the shape of the boat hull. The ribs may also prevent deformation of the hull. Also, a rib that provides support for a full level floor is needed.
BRIEF SUMMARY OF THE INVENTION
One aspect of the present invention is a method of making a portion of a boat (100), comprising the steps of: shearing a flat piece of metal to cut to a size (300); attaching said flat piece of metal to a moveable carriage (400); cutting apertures in said flat piece of metal (500); cut final outside dimensions in said flat piece of metal (600); bending said flat piece of metal to create a rib (700); and securing said rib to the floor (800).
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

FIG. 1 illustrates one embodiment on the present invention 10, which is a method of making a portion of a boat 100, such as a bottom of a boat. FIG. 1 includes a first step of obtaining a flat piece of metal 200, followed by shearing said flat piece of metal to cut to a size 300, clamping said flat piece of metal to a moveable carriage 400, cutting apertures in said flat piece of metal (reduce weight) 500, cut final outside dimensions in said flat piece of metal 600, bending said flat piece of metal (longitudinally, stiffener, helps keep shape) to create a rib 700, and welding said rib to the floor 800.
FIG. 2 illustrates an embodiment of a rib that may be created from the method 100 of FIG. 1. The rib 20 may have a rib first portion 22 that has a bottom edge 26 that may be curved so that it has a greater height at the middle than compared with the ends 60, such as the front or rear end 60. The rib 20 may have a rib second portion 24 that is oriented at a different angle than the rib first portion 22. The rib first portion 22 may have a rib aperture 50 therein. The rib aperture 50 may be created by the cutting step 500.
FIG. 3 illustrates the hull floor support system 10 with the rib 20. The angle 70 between the rib first portion 22 and the rib second portion 24 is also illustrated. The boat has a hull 30 and a floor 40.
FIG. 4 illustrates an embodiment of a rib 20 that is secured to the inside bottom of the boat hull 30.
FIG. 5 illustrates an embodiment of the present invention showing that the rib 20 is disposed upwardly from the inside bottom of the hull 30, and also illustrates that the boat floor 40 is disposed upwardly from the boat rib 20.
FIG. 6 illustrates one embodiment of the present invention showing the floor 40 above the ribs 20.
In one embodiment of the present invention, the ribs are aluminum having a thickness of about 0.118 inches.
