The very first line of my first post said this was intended for canoes and rec-kayaks. Large open cockpits with limited flotation and the likelihood of swamping beyond bailing once back inside.
I believe that is what was lost in the conversation.
In my case and what I believe should be normal for these boats is without flotation added to some degree and a group of boaters large enough to aid in rescues on calmer waters the boater should stay an easy swimming distance from shore at all times because self rescue and assisted rescue would likely be imposable. Swim to shore drag filled boat along tip and empty in shallow water resume paddling.
My hope like some others is to combine adequate flotation in two paired boats along with conservative paddling in calmer waters where assisted rescues would be possible for both parties. I don’t want to replace any other technique of reentry someone may be skilled at doing just possibly add another.
There is nothing new about using a stirrup in these open boats as mentioned above what may be new is how this couples the two boats with a hook to apply the weight of the one boat and passenger to keep the other boat from rolling. The coupling is only momentary when the stirrup is bearing weight. I kind of prefer that to anything like tying off to the second boat (mentioned above) as if something went wrong and the one climbing the stirrup became tangled once they stopped climbing they could quickly be free of the attachment.
Again I’m not suggesting anyone use this method with conventional kayaks
