Abstract: A folding portable boat is disclosed comprising two end hull sections and two middle hull sections each hull section being of a floatation material. The hull sections are hingedly interconnected adjacent to each other so they can be folded and unfolded in an accordion manner. The portable boat further comprises two seat boards, each collapsibly associated with one of the middle hull sections, and an arrangement of elastic cords for causing the seat boards to erect as the hull sections are unfolded and to collapse as the hull sections are folded.
