Like a brick. Not even close. Sorry. It does, however, come with a lanyard and a hole on the case through which to attach it. So I'm thinking as long as you keep it attached to yourself and you float, you should be good to go. And if you don't float, well then your phone isn't going to be much of a concern to you any more.
A floating key chain attached to it might do well...
