A watercraft comprising a chair with seat securely carried on said watercraft; said chair having a frame and comprising a seat frame,a back frame, said seat and back frames being joined via a hinged connection,the frames of both said seat and said back having material extending across the frame to provide a supported seating area and back support area,the underside front of said frame having two receptacles,an upper surface of said watercraft having secured thereto two spaced apart engagement elements for receiving said receptacles and engagement elements being shaped such that the receptacles can be inserted into and removed from the engagement elements only when the rear of the chair is rotated upwardly and forwardly about said engagement elements, said engagement elements and receptacles being locked together when the chair is rotated downwardly and rearwardly. 3. The watercraft of claim 2 wherein the watercraft is a kayak. 4. The watercraft of claim 2 wherein attachment means connect the rear of the seat to said watercraft to prevent said seat from pitching forward and disengaging said receptacles from said engagement elements. 5. A watercraft comprising: a deck surface,a cockpit,a seat secured to said cockpit,a support element pivotally attached to the bottom rear of said seat and having a distal end,a spring to hold the support element in a stowed position beneath said seat,a means for pivotally deploying said support element,said cockpit having multiple vertically disposed notches on a generally upright surface adjacent the rear of said seat, to receive the distal end of said support element when deployed and support the rear of said seat at multiple heights. 6. The watercraft of claim 5 wherein the watercraft is a kayak. 7. The watercraft of claim 5 wherein said support element comprises spaced apart members each having distal ends and said cockpit has spaced apart vertically displaced notches to support the rear of said seat. 8. A watercraft comprising: a seat securely carried on said watercraft, said seat having a frame,four tapered holes in proximity to the underside of the corners of said frame,four legs each having upper and lower ends, the upper ends being adapted to be removably receivable and held in said tapered holes,tension cords passing through each leg, one of end of said cord being attached at the underside of said frame, the other end being attached at the lower side of said leg,holding means associated with each leg to hold said leg in stowed position beneath said frame,said tension cords pulling the upper end of said legs toward said tapered holes when said holding means are released, allowing said upper end of said legs to be secured in said tapered holes and allowing manual withdrawal of said legs from said holes by applying tensioning force to said tension cords and allowing said legs to be returned to the stowed position. 9.
