When I was developing our Pack Canoes I really wanted them to be self rescue-able in the same way as a kayak so I incorporated self rescue loops that would later become the foundation for our catamaran system. This technique is dependent on the right kind of flotation, a kayak paddle, a canoe there is only carrying a day load, or if camping, the (hopefully waterproof) pack can be tossed over the side briefly. . So not a solution for every situation but absolutely worth practicing to add another
