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.

A folding portable boat comprising:
- a. two end hull sections and two middle hull sections each hull section being of a floatation material and each hull section having an outer portion, an inner portion and opposed lateral side portions;
- b. the hull sections being hingedly interconnected adjacent to each other so they can be folded and unfolded in an accordion manner with the inner portion of each end hull section hingedly connected to the outer portion of one middle hull section and the middle hull sections hingedly connected to each other at their inner portions;
- c. two seat boards each collapsibly associated with one of the middle hull sections;
- and
- d. an erecting/collapsing means for each seat board for causing the seat board to erect as the hull sections are unfolded and to collapse as the hull sections are folded.

- b. the hull sections being hingedly interconnected adjacent to each other so they can be folded and unfolded in an accordion manner with the inner portion of each end hull section hingedly connected to the outer portion of one middle hull section and the middle hull sections hingedly connected to each other at their inner portions;
- c. a back having an upper edge, a lower edge and two side edges the lower end hingedly connected to the outer portion of one of the middle hull sections;
- d. two flanges each extending perpendicularly from one of the two side edges of the back and each flange having an opening in that part of the flange extending from the upper edge of the back;
- e. two side boards, each being hingedly connected to one of the two lateral side portions of one of the middle hull sections;
- f. a seat board hingedly connected to the upper edge of the back;
- g. two elastic means each being affixed to one lateral side portion of one of the end hull sections and each elastic means extending through one of the openings in one of the flanges and from there affixed to one of the two side boards so that as the hull sections are unfolded in an accordion manner the two elastic means operate to pull the back to an upright vertical position while simultaneously pulling the two side boards to upright vertical positions with the seat board falling by gravity to a horizontal position perpendicular to the side boards and the back;
- d. a side board securing means for securing the side boards in upright vertical positions during use;
- and
- h. back securing means for securing the back in an upright vertical position during use.
