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.
Claims6
A collapsible boat comprising:
- a plurality of rigid hull sections hinged together along edges which meet in mating curves to form a hull prow and which extend longitudinally throughout the hull length and which are hinged together by means of flexible cord laced through mating apertures therein,
- flexible, water tight sealing strips that extend along said hinged edges,
- a flexible water tight stern panel that is fastened to stern ends of said hull sections in watertight engagement therewith,
- a stern thwart having a transom reinforcing back for positioning against said flexible stern panel,
- a midthwart having an upright panel for positioning in contact with said hull sections,
- a bow thwart extending across bow ends of said hull sections,
- and a single length of flexible cord that passes along one side of said hull to the other, laced to hold said stern thwart, said midthwart, and said bow thwart to said hull sections.
A collapsible boat comprising:
- a plurality of rigid hull sections hinged together along edges which extend longitudinally throughout the hull length and which are hinged together by means of flexible cord laced through mating apertures therein,
- flexible, watertight, sealing strips that extend along said hinged edges,
- a flexible watertight stern panel that is fastened to stern ends of said hull sections in watertight engagement therewith,
- a stern thwart having a transom reinforcing back for positioning against said flexible stern panel, and
- a midthwart having an upright panel for positioning in contact with said hull sections, opposing side braces at either end of said upright panel, spacer panels hinged to the upper extremities of said side braces, a transverse seat hingedly joined to said spacer panels so that said transverse seat resides at a level between the vertical extremities of said side braces, an upright seat support hingedly joined to the underside of said transverse seat, upright alignment blocks defining slots therebetween on said side braces for receiving and immobilizing the ends of said upright seat support, and all of said hinged joints of said midthwart are formed by flexible cord laced through mating apertures in the joined parts thereof.
