## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present application is a CIP to U.S. patent application Ser. No. 11/139,939 filed on May 27, 2005 now U.S. Pat. No. 7,111,569.


FIELD
The present embodiments relate generally to seat for a lightweight floating watercraft wherein the watercraft can be used for fishing and repair of bridges, installation of endangered water plants and other uses. The lightweight floating watercraft enables a person to sit or stand on the watercraft without flipping over during poling, rowing, fishing and other activities.
BACKGROUND
Fishing boats traditionally are standard monohull designs, such as those used for bass boats, Boston WhalersTM or standard rowboats. With monohull designs, fishermen could not stand up in a boat without flipping over the boat or simply falling out of the boat.
A need exists for a safer boat design with a hull design in which fisherman can stand up in during fishing, or poling without concern for tipping over that can be molded in a unitary construction that is fast to make, durable, and inexpensive to manufacture and has a sturdy seat that can be multifunctional and removable.
Metal bass boats, wooden boats and thick hulled fiberglass boats, like Boston Whalers' are heavy, and generally require at least two people to lift the boat onto a car top due to the weight. A need exists for an 11 foot to 18 foot watercraft that can be lifted and used by one person without strain and has a removable seat.
The present embodiments provide the seat for these types of stabilized fishing watercrafts.

The present embodiments relate to a molded two piece seat for sitting on or standing on, when using a lightweight watercraft. The seat can be used with watercraft that enables a person or two persons weighing up to a collective weight of 500 pounds to paddle or pole the watercraft from a standing position for fishing, for biological study of plant life or planting of endangered species or for repair of floating structures.
The molded two piece seat enables a biologist to safely protect samples taken during study, or a fisherman to hold his catch in a cool and safe container and then remove the seat without disturbing the contents for transport.
The molded two part seat is a floatation device wherein the walls of the seat can have foam filler disposed therein for insulation and floatation purposes.
The molded two piece seat is particularly usable on a watercraft described in detail in below.
The molded two piece seat has the benefit of being made from a strong, high density polymer homopolymer or copolymer for material, such as a polyamide like nylon.
The seat has a benefit in that it can hold at least three fishing poles simultaneously.
The seat has a benefit of having a pivoting lid that can also be sat upon or stood upon without deformation.
The seat is made of a material resistant to ultraviolet radiation degradation and is resistant to corrosive action from salt. The seat is also highly impact resistant and will hold it shape in the event it is dropped.
The inventive seat is made quickly, in 10% of the time of conventional wooden seats or other non-molded seats. The seat can be made at a fraction of the cost because material costs for molded seats are extremely low and only 1 person can run the molding process compared with multiple persons needed to craft custom seats in other fishing boats.
In an embodiment, the seat has four legs for engaging in grooves formed on the deck of a watercraft. Other embodiment have six legs. The grooves could be in the form of an insert placed in non-molded watercraft. The insert containing the grooves can then be secured to the deck of other types of flat watercraft, using screws or a similar device.
The exemplary watercraft to which this seat can be used is a highly stable watercraft requiring only a few inches of water to float, generally less than six inches of water, and generally not more than 3 inches of water.
The exemplary watercraft is a one piece molded watercraft having a port and a starboard hull extension connected by a bridge and a tapered graduated water channel formed between the bow and stern in the bottom of the watercraft.
The graduated channel provides for increased stability in the watercraft and allows a person(s) to stand and sit on the exemplary watercraft without tipping the watercraft or enabling the watercraft to be loaded to over 500 pound of gear without tipping over, while maintaining a draft of only a few inches. Embodiments of the exemplary watercraft can be watercraft between 10 feet to 20 feet in length. Exemplary watercrafts for use of the seat can have lengths of 10.5 feet, 14 feet, 16 feet, and 18 feet.
The exemplary watercraft has sloped edges that extend from bow to stern. A deck is formed located over and integral with the sloped edges.
In a preferred embodiment, the material of an exemplary watercraft on which the seat would operate is a watercraft made from a moldable curable polymer, or polymer composite. If a simple curable polymer is used, the polymer may be a homopolymer or a copolymer. The polymer can be polyamide but can contain optionally polypropylene, polyethylene, resins, or even some fiberglass,
Inside the exemplary watercraft is inserted an expandable liquid foam to enhance buoyancy of the watercraft and to increase strength of the watercraft to prevent deformation or collapse of the watercraft from selected weights being placed on the watercraft.
In one embodiment a molded seat for individually propelled watercraft having a deck with sloped sides extending there from and a plurality of opposing grooves of a defined shape formed in the deck and sloping sides. The seat can have a multi-component raised friction fitting non-sliding removable base expending above a deck comprising a molded foam filled insulated container. The base can have at least 4 legs to integrate into corresponding grooves formed into the deck, where the base can have a bottom integral with the at least 4 legs and 4 integral side walls rising from the bottom, and where two side walls opposing each other can have small extensions to extend over the sloping sides of a watercraft for a secure engagement with the watercraft and where at least one side wall comprises at least one rod holder. The base can also have a pivoting insulated lid secured to the base container in addition to having the ability for the legs of the base container fit snugly into the opposing grooves of substantially the same shape as the legs.

The graduated channel 11 is between the port hull section 12 and the starboard hull section 14.
In this bottom view, the port and starboard hull section and the graduated channel each contain 4 support columns that extend from the bottom of the hull interior to the deck. The port hull section bottom 28 sports port support columns 13a, 13b, 13c, 13d, and 13e while starboard hull section bottom 30 sports starboard support columns 15a, 15b, 15c, 15d and 15e. The vessel can have at least 4 support columns and up to 10 support columns are in each hull section and between 3 and 10 support columns are in the mid hull section.
The bottom of the hull forming the channel is the mid hull section 16 and has mid hull section support columns 17a, 17b, 17c, 17d, 17e and 17f. 
Integral to the bottom of the hull and penetrating to the deck, is a bow hole 20 forming the bow handle 22 and a stern hole 24 forming the stern handle 26.
The port hull section and starboard hull section each have sloped edges, the port side hull is shown in FIG. 2. The sloped edges enable waves to roll down the craft, giving the craft a quieter effect on the water, having less wave noise, making the vessel less likely to scare endangered species like manatee, and to provide fishermen with the ability to not scare fish off. The sloped edges enable the vessel to have a stealth quality, it is designed to be extremely quiet with this design.
The watercraft requires very little draft. For example, the watercraft can use only three inches of draft, thereby making the watercraft usable in the shallowest of bodies of water of just a few inches while supporting a 165 pound man and a 100 pound Labrador retriever.
