The watercraft as recited in claim 1, wherein the ramp has an upper end, and a lower end located proximate the stern, and the upper end of the ramp is relatively wider than the lower end of the ramp. 19. The watercraft as recited in claim 1, further comprising a first side rail located proximate a first side of the ramp, and a second side rail located proximate a second side of the ramp, wherein the first and second sides of the ramp are disposed opposite each other. 20. The watercraft as recited in claim 1, wherein the ramp is recessed within the body. 21. The watercraft as recited in claim 1, wherein the ramp is located on top of the body. 22. The watercraft as recited in claim 1, wherein the ramp is located proximate the stern of the watercraft. 23. The watercraft as recited in claim 1, further comprising a transom located proximate the stern and intersected by the ramp. 24. The watercraft as recited in claim 1, wherein one of the longitudinal recesses is relatively wider in a middle portion of that longitudinal recess than at an end portion of that longitudinal recess. 25. The watercraft as recited in claim 1, wherein one of the longitudinal recesses has a width that is less than about 20 percent of an overall width of the watercraft. 26. The watercraft as recited in claim 1, wherein one of the longitudinal recesses has a width that is greater than about 20 percent of an overall width of the watercraft. 27.
