Brad, I split this off into its own topic. One (maybe limited) perspective ...
Space aside, there are inflatables and inflatables. Jim (Wasoki) and I have/had what is called a RIB, aka rigid inflatable boat; They have a fiberglass hull with inflatable tubes attached. These are very stable, sit "high" in the water, can handle rougher water, and usually are rated for a higher hp engine. Ours is 13 ft long and has a 40hp engine. It also has an off-center console/helm with a steering wheel and throttle/gear shift, in addition to comfortable seats. That fiberglass hull makes it quite heavy, and tough to carry on a larger boat without a davit or crane, so many folks tow them. Our mother boat has a hydraulic swim platform, making it much easier to carry the RIB.
Non-RIB inflatables are much lighter and easier to carry aboard as a dinghy. They usually have a stern-mounted outboard engine with a tiller, and they often have less comfortable "plank" seats (a solid piece of fiberglass). Their inflatable keel means that they're a lot more "flexible" (and uncomfortable) in rough water.
There's an in-between type of inflatable that has a "rigid bottom", often pieces of wood inserted on the floor of the boat. They're frequently meant to be "rolled up" after use (after removing the wood floor), but my experience with this type of inflatable was such that it wasn't easy putting it together and taking it apart; As a result, it was kept inflated with the floor inserted.
All 3 versions of inflatables make great boats for toodling around the neighborhood, but their comfort level in rough water varies..
FWIW when we lived in the UK, the Royal National Lifeboat Institute used near-unsinkable lifeboats for offshore rescue, but their inshore boats were all Avon inflatables, and considered quite safe.
