Narration:

This animation graphically demonstrates the heeling accident on the passenger ship Crown Princess.
Slightly more than an hour after departing Port Canaveral, the ship’s automatic steering system began a turn to port.
The second officer sees the ship turning to port at a high rate and becomes concerned.
He turns off the autopilot and takes manual control of the steering.
Instead of turning the wheel to starboard to slow the port turn, he turns the wheel to port.
He then starts turning the wheel back and forth between port and starboard.
The ship begins to heel to starboard.
The second officer continues turning the wheel between port and starboard.
The three senior officers return to the bridge.
An officer orders, “Reduce the speed”.
The ship reaches its maximum angle of heel to starboard.
The captain orders, “Stop the engines”.
The captain uses the public address system to advise the passengers to sit down where they are.
While the ship slows, a senior officer turns to wheel hard to starboard.
As the rate of turn is reduced, the ship approaches even keel.
About three minutes after the second officer engaged manual steering, the Crown Princess returns to even keel.
