Abstract: A rigid collapsible boat has a plurality of rigid hull sections hinged together along mating, longitudinally extending edges throughout the hull length. The joints are hinged with flexible nylon cord and are sealed watertight by sealing strips that extend longitudinally along the hinged edges. A flexible, watertight stern panel is fastened across the stern ends of the hull sections. A stern thwart, with a transom reinforcing back, a midthwart, extending across the beam of the boat, and a bow thwart provide rigid support to the boat. The hull sections and thwarts are all fastened together by means of flexible nylon cord that is laced through apertures in the thwarts and in the hull sections.
