And KayakMike, good thoughts there, but I kinda like the idea of the self-inflating feature incase I bang my noggin on the way outta the boat and can't pull the ripcord myself.
That's definitely a worthwhile consideration.
However, I recommend double checking with the manufacturer and perhaps even coast guard/OPP at boat show etc....as that is in fact the distinction between life vest and pfd....a pfd is not rated to keep your noggin out of the water in the event of such a mishap. If that is a major concern, I would take my time and do more research.
