Collapsible boat with enhanced rigidity and multi-function chair

A collapsible portable boat with enhanced longitudinal rigidity, comprising:

• a skeleton frame and hull, said hull comprised of flexible material, including at least one end stem section, and gunwales connected to each other by a gunwale connector, and lengthwise support stringers disposed along the length of the boat along the bottom and sides of the boat and support formers arranged transverse to said lengthwise support stringers;
• a floor section affixed to that portion of the hull section which defines the bottom of the boat and which floor section is disposed as between the stringers and the flexible material of the hull;
• and
• an inflatable tensioner for tensioning as between said skeleton structure and the outer flexible hull positioned as between the hull and support stringers, characterized in that the tension substantially reduces hull flex, and wherein the end stem section contains an end stem connector for connecting and securing the gunwale connector in said end stem section, further characterized in that said tensioner for tensioning as between said skeleton structure and outer flexible hull is itself retained by said support stringer such that said tensioner will not substantially reposition itself relative to said stringer when said canoe is exposed to a longitudinal hull flex.

A collapsible portable boat with enhanced longitudinal rigidity, comprising:

• a main skeleton frame and hull, including at least one end stem section, and gunwales connected to each other by a gunwale connector, further characterized in that the hull is of flexible material and lengthwise support stringers are disposed along the length of the boat along the bottom and sides of the boat and support formers are arranged transverse to said lengthwise support stringers, wherein the end stem section contains a connector for connecting and securing the gunwales connector to said end stem section,
• a floor section affixed to that portion of the hull section which defines the bottom of the boat and which is disposed as between the stringers and the flexible material of the hull,
• characterized in that the support stringers themselves comprise a plurality of sectional support elements which are affixed to one another by tension;
• and
• a tensioner for developing tension as between said skeleton frame and the outer flexible hull positioned as between the flexible material of the hull and the skeleton, characterized in that the tensioner for tensioning as between said skeleton structure and outer flexible hull is itself retained by said support stringers such that said tensioner will not substantially reposition itself relative to said stringer when said canoe is exposed to a longitudinal hull flex.

A multi-function/positioned chair or saddle for a watercraft which can be adjusted as between sitting, kneeling and portaging positions, comprising

• a seat which contains a front, rear, top and bottom sections;
• a portaging support on the front section of said set for supporting the seat when used as a portage yoke wherein the portaging yoke comprises a cut-out section;
• and
• a supporting framework connected to said seat, said supporting framework comprising a first and second leg member pivotally attached at the rear of said seat, wherein said first and second leg member are substantially disposed in use in the form of an inverted V, and a third leg member pivotally attached to said seat wherein said third leg member can support said second leg member to thereby position said seat in a sitting, kneeling or portaging position.
