Factual error: After the boat has blown up and sunk, Ben swims over to it and checks it out, very little to anything is even a little charred, with that big of an explosion everything would be burnt, and black.
Factual error: In the beginning of the movie after Tess' divorce and she wants to pursue Nigel to weigh anchor she says that it doesn't make sense to wait at Key West for the helicopter with Gemma. However in the background there are islands with quite high hills visible. The highest elevation in the whole Florida Keys (where Key West belongs to) is 18 feet. (00:27:25)
Factual error: Toward the end when the speedboats steer toward Ben, if you look at his hair you can see that part of it is dry even though he just came up from under the water.
Factual error: When the 206 crashes towards the end of the movie, you can see the prop still spinning under the water. In reality the engine would have stopped and compression would not have allowed this to happen. Also the blades would have been bent and not broken off as you only see two.
