"(After the ship has capsized) Now we're not sure exactly what happened here, but our best guess is that we were struck by what is known as a rogue wave. They are rare, they are unpredictable, and they are lethal, Now the good news. The instant this ship was struck, emergency GPS locater beacons were launched, so we are at most, several hours from rescue. [This announcement causes panicked chatter to rise from the Passengers; a few ask if the ship is sinking] Please, do yourselves a favor. Follow the directions of my officers, and stay calm. This room is a giant air bubble holding up the ship. Once these bulkhead doors are sealed, we will be safe from gas leaks, fire, and flooding. We will be safe."
