At the dink dock I would guess 1 out of 50 dink have air floor. so it can be done. I have also seen carpet laid on top of the air floor to add some durably
I would say that I see more Porta-Bote and that is the way I would go for a 26' boat,
We have an 37 ft cutter and there is no room for a 10' RIB on our decks unless we deflate it, it hangs off the stern and I would question if that what a seriously cruiser would do. I think it would be easy to lose the whole thing if it ever fill up with water.
