What is claimed is:

1. A pontoon boat, comprising: first and second inflatable elongated pontoons arranged to be approximately parallel to each other and separated by a predetermined distance; a plurality of pairs of upwardly extending strips formed in a longitudinal direction on both sides of a centerline of a top of the first and second pontoons; a plurality of transversal slats connecting the first pontoon to the second pontoon, a bottomof each slat including engaging means for engaging the strips of the first and second pontoons, a number of the plurality of slats being equal to a number of the plurality of pairs of strips; and first and second underbars, the first underbar beingpositioned in a longitudinal direction on the top of the first pontoon in between the pairs of strips and below the slat, the second underbar being positioned in a longitudinal direction on the top of the second pontoon in between the pairs of strips andbelow the slat.

2. The pontoon boat of claim 1, wherein the strip further comprises a dowel formed longitudinally on an uppermost part of the strip and the engaging means comprises a seat hook dimensioned and configured to secure the dowel.

3. The pontoon boat of claim 1, wherein the first and second pontoons are each constructed of polyester fabric and further include an air valve.

4. The pontoon boat of claim 1, wherein the first and second pontoons each further comprises: a tapered fore and aft end; a molded nose cone attached to each of the tapered fore and aft end; and four skegs, one skeg attached to a bottom sideof the fore and aft end of each of the first and second pontoons.

5. The pontoon boat of claim 1, further comprising a bow bar footrest extending between the first and second pontoons at a forward end of the pontoon boat.

6. The pontoon boat of claim 1, further comprising a bench stepboard extending between the first and second pontoons at a forward end of the pontoon boat.

7. The pontoon boat of claim 1, wherein the slats are aluminum.

8. The pontoon boat of claim 1, wherein the slats include at least one fishing rod holder.

9. The pontoon boat of claim 1, wherein the slats include a bracket for a chair.

10. The pontoon boat of claim 1, wherein the slats include a transom.

11. The pontoon boat of claim 1, wherein each of the first and second underbars comprises two or more sections.

12. The pontoon boat of claim 1, wherein the first and second underbars are aluminum.

13. The pontoon boat of claim 1, further comprising a flexible floor extending between the first pontoon and the second pontoon, the floor being positioned below the slats and connected to an inboard side of the first pontoon and an inboardside of the second pontoon.

14. The pontoon boat of claim 1, further comprising a plurality of floor segments removably attached to a fore and aft side of successive slats, wherein each floor segment covers an open space between the slats.

15. A method of assembling a pontoon boat, the pontoon boat including first and second inflatable pontoons, the pontoons being connected to each other by a plurality of transversal slats, each slat being connected to the pontoon by a pair ofupwardly extending strips formed in a longitudinal direction on both sides of a centerline of a top of the first and second pontoons, the method comprising: unrolling the pontoon boat so that the pontoons are substantially flat; inserting one or moreunderbars along a top of each pontoon so that the underbar is positioned in between the strips and below the slats; and inflating the pontoons with air so that the one or more underbars are secured between the top of the pontoons and the bottom of theslats.

16. The method of claim 15, wherein the first and second pontoons are each inflated through an air valve.

17. The method of claim 15, further comprising extending a bow bar footrest between the first and second pontoons at a forward end of the pontoon boat.

18. The method of claim 15, further comprising removably attaching at least one fishing rod to the slats.

19. The method of claim 15, further comprising removably attaching a chair to the slats.

20. The method of claim 15, further comprising connecting a flexible floor between the first pontoon and the second pontoon, the floor being positioned below the slats and connected to an inboard side of the first pontoon and an inboard side ofthe second pontoon.

21. The method of claim 15, further comprising connecting a plurality of flexible floor segments between a fore and aft sides of successive slats, wherein each floor segment covers an open space between the slats.
