Longitudinal bow and stern beams are disposed vertically within a kayak hull. A stiffening tube extends beneath the beams. A tube and the beam holder overlaps a lower portion of each beam and rests on the center portion of the stiffening tube for holding the stiffening tube in place and tying the bow and the stern beams together. The holder is maintained in place by a seat which is pressure fit within the cockpit of the kayak. The upper ends of the bow and stern beams are restrained from lateral movement by upper beam holders mounted to the kayak hull. The system allows greater flexure of the kayak hull with less likelihood of the bow and stern beams becoming dislodged.
