Collapsible kayak

A collapsible water vessel comprising:

• a center hull section;
• a first plurality of hull extensions longitudinally slidable through an opening at a first end of said center hull section between extended and collapsed positions;
• a second plurality of hull extensions longitudinally slidable through an opening at a second end of said center hull section between extended and collapsed positions;
• wherein when said first plurality of hull extension are in the extended configuration adjacent hull extensions thereof form a sealing contact therebetween and an inboard most hull extension thereof forms a sealing contact with said center hull section;
• and
• wherein when said second plurality of hull extension are in the extended configuration adjacent hull extensions thereof form a sealing contact therebetween and an inboard most hull extension thereof forms a sealing contact with said center hull section;
• a first extensible tension spar attached at one end to an outboard most hull extension of said first plurality of hull extensions and connected at an opposite end to said center hull section;
• a second extensible tension spar attached at one end to said outboard most hull extension of said plurality of hull extensions and connected at an opposite end to said center hull section;
• a third extensible tension spar attached at one end to an outboard most hull extension of said second plurality of hull extension and connected at an opposite end to said center hull section;
• a fourth extensible tension spar attached at one end to an outboard most hull extension of said second plurality of hull extensions and connected at an opposite end to said center hull section;
• said first and second extensible tension spars disposed along opposite sides of said first plurality of hull extensions, and when said first plurality of hull extension are in the extended position said first and second extensible tension spars are curved in opposite directions;
• and
• said third and fourth extensible tension spars disposed along opposite sides of said first plurality of hull extensions, and when said second plurality of hull extension are in the extended position said third and fourth extensible tension spars are curved in opposite directions.
