Don't book a cruise

I wouldn't call a 25M wave mini. That's pretty f'in big.

Yeah, but full-on tsunamis can be 100s of metres high. It's all relative.

[Cliphead]

Yeah, but full-on tsunamis can be 100s of metres high. It's all relative.

Not unless you're near the shore. A tsunami out at sea would pass unnoticed by any ships.

[Moscow Mule]

Yeah, but full-on tsunamis can be 100s of metres high. It's all relative.

Nah, that's them mega-tsunamis. Regular tsunamis are in the 10-30M range.

I sometimes study this phenomenon. Every now and then a big wave builds up in the gym's jacuzzi and you get jacuzzi water in your eyes, which is most unpleasant. The effect is less pronounced in the main swimming pool, where waves big enough to sink an oil tanker are very rare.

I once depth-charged from the low board and the three centimetre shock wave was enough to get me banned for a month

so even small waves can be serious

Details:

As Hurricane Luis churned the Gulf and later the Atlantic Ocean, the seas became unfit for fish or man.

She was on Trans Atlantic Voyage Number 1014, Westbound from Southampton and Cherbourg to New York City. The vessel disembarked on September 7 set to arrive in New York on September 12.

The ship was slammed by a 95 foot high wave, followed by two smaller waves. The captain, Captain Warwick, reported winds to 130 miles per hour with average wave heights of 40 feet.

The 95 foot wave hit as most passengers were asleep in their beds, those who could sleep being tossed all night, at 0410 hours (4:10am)

The captain had changed course to avoid the hurricane, but the storm had created high seas, with huge swells over a wide area. Even though the swells were high, the captain and crew on the bridge say they were not hit by a swell, but instead a rogue wave.

The captain said, "At 0410 the rogue wave was sighted right ahead, looming out of the darkness from 220°, it looked as though the ship was heading straight for the white cliffs of Dover. The wave seemed to take ages to arrive but it was probably less than a minute before it broke with tremendous force over the bow. An incredible shudder went through the ship, followed a few minutes later by two smaller shudders. There seemed to be two waves in succession as the ship fell into the 'hole' behind the first one. The second wave of 28-29 m (period 13 seconds), whilst breaking, crashed over the foredeck, carrying away the forward whistle mast."

The presence of extreme waves was also recorded by Canadian weather buoys moored in the area, and the maximum measured height from buoy 44141 was 30 meters (98 feet.). This further verified the captain's report.

While this wave was huge, it was nothing compare to predicted waves of the future.

Scientists predict that if a future volcanic eruption sends a large part of the island of La Palma in the Canaries into the sea, it could cause a wall of water 2,950ft high.

Thought I remembered something about this...

"Scientists predict that if a future volcanic eruption sends a large part of the island of La Palma in the Canaries into the sea, it could cause a wall of water 2,950ft high. "

Yes that would cause a tsunami that would wreck the south coast of England.
And it's only a matter of time.

And they say flying is dangerous.

Who says flying is dangerous? It's extremely safe. As is going on a cruise.

But tell you what - you just stay in Swindon and hide.

[BrilloPad]

There was a steel ore cargo ship sumk on one of the great lakes. Reckoned to be by a super wave.

Something to do with normal waves combining or something.
