Raft tied to a boat, just offshore
From BearWiki
Claim: Bear's raft was right next to the camera chase boat.
While Bear labels this photo as from after the shooting, it is clear that he wasn't the only person on the raft (given the camera angles). Also given that there was a diver involved in the filming of at least part of this scene, and the director talked about how "we" beat on the raft to try and scare the sharks away, Bear must have been in close contact with the chase boat the whole time.
