Continuity mistake: The way Annie holds the grenade changes instantly between shots. (01:09:30)
Continuity mistake: When Geiger is setting off from the ship, in the background, the stern door is almost shut. Camera cuts to Alex on the stern door and it is nowhere near shut. (01:23:15)
Continuity mistake: At the start the doors to the van are open in some shots and closed in others. Mainly noticeable when the driver spots the SWAT team. (00:04:50)
Other mistake: The bow thruster is activated to avoid colliding with the oil tanker. Since the thruster is never turned off, the cruise ship should have continued on traveling in circles. However, after scraping the oil tanker the cruise ship travels in a straight line into the island.
Continuity mistake: Just before the evacuation, the ship stops. When Merced runs to the computer in the bridge, the speed indicator shows 18.2 knots.
Continuity mistake: When Alex surfaces from under the ship, he chucks his mask off and it floats away. Once Geiger has forced Annie to drop Alex back into the water, he suddenly has the mask back. (01:21:00)
Answer: The ship has no way to stop or steer. By hitting land it would bring the ship to a stop (at a considerable cost) where as if they go out to sea, they would just continue to keep going until out of fuel or hit something they can't avoid and risk everyone drowning. A risk that is not present if they hit land.
