A twin-hull paddle board for use while standing or sitting down, the twin-hull paddle board consists of two elongated hulls, a flat platform portion having two side edges, a front edge and a back edge, the platform portion connected across the top of the two hulls intermediate between the front ends and the back ends of each hull, the flat platform portion and the tops of the hulls forming an upper deck portion, the upper deck portion comprising two recessed foot wells placed adjacent to the side edges of the flat platform portion, the recessed foot wells contoured to prevent accumulation or puddling of water during use, and a coupling mechanism for removably coupling the leg portion of the removable seat to the upper deck portion of the paddle board.

1. A twin-hull stand up paddle board, the twin-hull paddle board comprising: two elongated hulls, the hulls contoured to have top surfaces, pointed front ends and pointed back ends, the two hulls positioned parallel to each other; anda flat platform portion having two side edges, a front edge and a
1. A twin-hull stand up paddle board, the twin-hull paddle board comprising: two elongated hulls, the hulls contoured to have top surfaces, pointed front ends and pointed back ends, the two hulls positioned parallel to each other; anda flat platform portion having two side edges, a front edge and a back edge, the platform portion connected across the top of the two hulls intermediate between the front ends and the back ends of each hull, the flat platform portion and the tops of the hulls forming an upper deck portion, the upper deck portion and the top surfaces of the elongated hulls having a very low profile such that the distance between the upper deck portion and the top surfaces of the elongated hulls and the surface of the water is minimized, thereby decreasing resistance to wind against the twin-hull paddle board, the upper deck portion comprising two recessed foot wells placed adjacent to the side edges of the flat platform portion, the recessed foot wells contoured to prevent accumulation or puddling of water during use, the upper deck portion further having a lower surface which stays above the surface of the water, the upper deck portion further having a deep-V shape at the front edge of the platform area and a deep-V shape at the back edge of the platform portion, whereby instability of the twin-hull stand up paddle board caused by waves and front wake is eliminated. 2. The twin-hull paddle board of claim 1, wherein the top surfaces of the hulls have a side-to-side cross section profile selected from the group of shapes consisting of flat, curved, bell, arched, and V-shaped. 3. The twin-hull paddle board of claim 1 in which each of two hulls further comprise a rear fin, thereby increasing stability of the paddle board. 4. The twin-hull paddle board of claim 3 in which each of the rear fins has an upper portion in which a section of material has been removed and an enlarged lower portion which provides increased stability compared with a conventional, solid fin. 5. The twin-hull paddle board of claim 1 in which the removable seat further comprises a lower plate portion and the coupling mechanism couples the lower plate portion to the flat platform portion. 6. The twin-hull paddle board of claim 1 further comprising a viewing window portion attached to the front edge of the flat platform portion by mechanical means, the viewing window portion further comprising a top panel and a bottom panel, at least the bottom panel made of transparent material, four side panels positioned between the top and bottom panels, four side panels further assembled to a shape fitted snugly to the front panel of the flat platform portion. 7. The twin-hull paddle board of claim 6 in which one or more side panels of the viewing window portion are constructed with transparent materials. 8. The twin-hull paddle board of claim 3 in which each of the rear fins has a center portion in which a section of material has been removed and an enlarged lower portion which provides increased stability compared with a conventional, solid fin. 9. The twin-hull paddle board of claim 1 wherein the deep-V shaped front edge of the upper deck portion begins at a point about 20% of the length of the paddle board from the front ends of the hull portions and extends rearward to a point about 37.5% of the length of the paddle board from the front ends. 10. The twin-hull paddle board of claim 1 wherein the upper deck portion further comprises an opening placed centrally in the flat platform portion. 11. The twin-hull paddle board of claim 1, further comprising a removable seat comprising a flat seat top integrally connected to a leg portion, wherein the stand up paddle board of the present invention can be used for stand up paddling as well as paddling while seated on the removable seat. 12. The twin-hull paddle board of claim 11 further comprising a coupling mechanism for removably coupling the leg portion of the removable seat to the upper deck portion of the paddle board.
