From the direction, I'd say that's a fair guess. Hopefully, the hull breach is small.

[A smaller hole means more time afloat. The Titanic took less than three hours, he expects that the Gamemakers will want more footage than that would allow.

He readjusts the rope on his shoulder as they come to a cross section, pausing to look down both corridors, but nods for them to continue straight.]

Well, they'll draw this out, so my guess is four to seven hours.
