First line can just about sum it up...........He comes out and tells you that he's using water as the metaphor. He knows that men can't fly meaning he's gonna have to deal with this water somehow. He's pretending to be a boat. While being the boat, he's gonna ride upon the rough waves (hard times) and just "go with the flow" to get through it anyway he can. If his life is goin well, he's just gonna float in the water without a boat.
