It was just assumed he was on the ferry because his car was in the parking lot. His partner was taken from the ferry the night before, killed, and fed to crocs. His body and/or phone could never have been in the water near the ferry.

If he just called his partner and a cell phone in a body bag started ringing at the same time it seems to me a trained official of the law would be a little curious and take a peek inside.

that the two timelines partially morphed into one? That's what it appears to be. In the beginning of the movie, the car with the bomb is locked, has keys in the ignition, and the radio is playing...because in Dimension # 2, the girl has done that in the car (turned it on, radio on). Also, same with the answering machine message from Beth ("Beth, is this a joke?"), which shouldn't have had Claire talking on it if she was killed earlier that day in Scenario #1.

Also, the thing that Jim Caviezel tells Denzel about fate, he only says it to Caviezel because Denzel says it to him on the ship before the bomb goes off...And that's why he tells Denzel...and that's why Denzel tells Caviezel...and so forth and so forth. It's all sort of "The Terminator" syndrome, I guess, which I actually think is always a nifty thing, even though it can give you a headache to think about it too much

Towards the beginning after the ferry gets blowed up, Denzel arrives, and is looking at rows of bodies in body bags. A cell phone rings, he looks at his phone thinking its his, but its not. He looks over at the body bag and notices its coming from inside of the bag? Whats the deal? Is that Denzel's body in the bag? I thought that was interesting.
