As far as the small fires, if its in a light enough vessel you could slide it around so that no one part of the raft gets too hot. A water jacket would probably be the most practical though.
It's true that a very thin vessel full of water can be directly exposed to fire, but unless you can make your rafts out of giant very strong doritos this isn't going to help.
(sorry- that was supposed to be an edit, not another post.)
