Video has captured the Queen Mary 2 battling a ferocious storm far out at sea.
The Cunard ship is specifically built to cruise smoothly through the most unrelenting of weather.
But powerful storms can still be an unsettling experience for passengers on board.
The footage – posted to YouTube in 2011 – captured raging seas bashing the sides of the huge boat as it crossed the Atlantic Ocean after it departed Southampton.
Taken from a window in the lower deck, the stomach-flipping clip showed the cruise rise up and crash down against the giant waves outside.
One of the railings had been ripped off by the violent walls of water lashing the upper decks.
The incredible video has been viewed more than 5.7 million times since it was shared online.
One YouTube user commented: “Certainly a cruise more exciting than a rollercoaster ride!”
Another wrote: “I get sea sick just watching this”.
One person said: “At first I thought. Ahhh that’s nothing. But then went he went to the lower decks, and I saw how big the swells were. I ate my words.”
The Queen Mary 2 regularly traverses the Transatlantic Crossing as it travels between the UK and New York.
It weighs 148,528 tons and can carry up to 1,300 passengers at a time.
Express.co.uk has reached out to Cunard for comment.
Another video of a cruise ship being battered by a storm quickly went viral online.
The CCTV camera from one of the dining areas of the ship overlooked the bar and a series of pillars, surrounded by tables and chairs.
As bar staff leaned on benches to steady themselves, the chairs and tables swung with the rocking of the ship.
Flying towards one end in a heap, the furniture crashed past passengers and other staff members who were trying to get out of harm’s way.
