The bridge that is flooded seems to be located much lower than the bridge of the cruise ship. It's scary enough to look at, but I think it's a smaller vessel that gets hit by the wall of water.


Your theory seems very true...becasue when i checked back the clip i realised something on the bow. The Forecastle doesnt look like Voyager...then the bridge windows doesnt look like it either. The spacing and shape of the windows arent correct...If i reemember corrrectly, all the Wheelhouse windows on the Grand Voyager and Explorer are the same size right across...and in the clip it doesnt seem like that.. Looks like they merged two separate clips...

Flexing Innards

Look at this video, submitted by one Charles Daniel from a commercial container ship to Military.com Entertainment, with the comment:
'The seas I could deal with. Same goes for the pitching of the vessel. I don't know about those flexing passageways though...'

Hi,

That is a well put together video of the whole ship not just the water over the front.

I have heard an ex shipmate talk about the waves in the steel deck on a 95m Factory Trawler whilst fishing in 80 kt winds, he also told me that in 6 yrs of trip on trip off as Chief Engineer they only had to stop fishing once because it was too rough.

Needless to say he now works on a yacht!!

This looks a little unsettling

That's a video of the 'Grand Voyager' (ex. Olympia Voyager, Olympic Voyager). One of two twin vessels constructed originally for Royal Olympic Cruises (ROC). The other is 'Explorer' (ex. Olympia Explorer, Olympic Explorer). Funny enough both ships were involved in very rough seas on the opposite sides of the globe really around the same time.

Rogue waves VS Freak waves

With modern satellite imagry scientist are seeing rogue waves and freak waves on a regular basis. Rogue waves are fairly common especially on along the Northwest USA in the winter time or the Bay of Biscay. Freak waves will take out just abut any size ship. There is very little understanding of why they are formed but they are seeing now fairly often popping up to close to 100' on satellite imagry.the following is abrief description.

Rogue waves are relatively large and spontaneous ocean surface waves that are a threat even to large ships and ocean liners. In oceanography, they are more precisely defined as waves whose height is more than twice the significant wave height (SWH), which is itself defined as the mean of the largest third of waves in a wave record. Therefore rogue waves are not necessarily the biggest waves found at sea; they are, rather, surprisingly large waves for a given sea state. A 6-metre (20 ft) caused the loss of the RV Ballena in Southern California.

Freak waves have been cited in the media as a likely source of the sudden, inexplicable disappearance of many ocean-going vessels. The 1978 loss of the freighter MS München. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough west of Scotland encountered the largest waves ever recorded by scientific instruments in the open ocean, with a SWH of 18.5 metres (61 ft) and individual waves up to 29.1 metres (95 ft).[5]


"Waves Happen" and even the most capable and well built boats when encountering a wave of this magnitude can suffer heavy damage or worse.

An interesting explanation.
Documentary on Freak Waves in 5 parts.

After watching the above a couple of times and thinking about the forces noted I looked at some structures that I'm familiar with and what would happen if they were nailed with a hundred tonnes per square metre. Not nice.
