  • Portable self-rescue device for kayakers
    Patent number: 6769378

The invention has an extendible telescopic arm with a proximal end and a distal end, a collapsible container attached to the distal end of the extendible telescopic arm and a collapsible ladder platform assembly with a retractable step.
