TB - good thought.
My dinghy typically is on the davits, 4 part block and not quick release -able.
I do carry a bright orange kayak awarthship on my aft walkway in front of the hammock and right next to my life ring. It would be a fast toss for me (it weighs 36 pounds so I can 'shot put' it off the back). My admiral would not be able to shot put it off (thank god, I think) but it would be better than nothing if she kicked it and let it fall over (it's normally tied with a quick knot).
