Rogue Wave Video - Best I Have Seen
Ahoy Sailors!
Sailors Fear Rogue Waves (For very good reason!)
This new (just published yesterday) outstanding short video does an excellent job of explaining the phenomenon known as a “Rogue Wave.” The video has excellent graphics, animation, narration, and comparisons of sizes of waves.
It includes recent information (data on wave height) and very good animations that “put you on the bridge” of a ship about to hit one. As the video shows, recorded wave height of 155 feet is something that has a lot of force and energy.
While I have read many things about Rogue Waves, this is the best presentation I have seen that describes them in such a short video.
I encourage you to watch this and share it with other sailors.

Re: Rogue Wave Video - Best I Have Seen
Good video
Trust me when I say you never want to encounter one of these .
I encountered a 10o ft + one in the south China sea in 1989 thankfully I was on the biggest military vessel that existed at the time .( the USS Carl Vinson CVAN70) we suffered millions in damage to the ship and the loss of life of one of my men .solid water washed the flight deck . That experience is one I never want anyone to have.

Re: Rogue Wave Video - Best I Have Seen
Great, I’m adding rogue waves to my list of personal nightmares. Thanks

Re: Rogue Wave Video - Best I Have Seen
Newhaul, how did the smaller vessels escorting the Vinson fair?

Re: Rogue Wave Video - Best I Have Seen
Thanks a lot for posting. The steepness is what terrifies me. Great fun running hard in big swells but only if they aren't breaking OR TOO STEEP

they were not involved in the area due to 2 super typhoons they were thankfully on typhoons evasion except the USS Texas she was at general quarters when hit she thankfully dove straight through the first one and was out of the strike zone of the second.
Superficial damages only

Re: Rogue Wave Video - Best I Have Seen
Wow, very sobering. It seems that these waves are most often in storms, but that doesn't seem like a necessary component.

been through small ( under 7 to 10 meter) rogues that just appeared out of nowhere on nice sunny days

Re: Rogue Wave Video - Best I Have Seen
Kind of disagree with the video , a rogue wave can't make a big ship to lose steering , even with the bridge destroyed you can still control the ship within the engine room or even directly above the rudder controling the pumps.
About breaking ships apart this used to happen even without rogue waves so we can't blame rogue wave for that .
The real question is not what the cargo ships will suffer from a rogue wave but a sail boat .
If we think a monohull will right up .
Trimarans will stay capsized but afloat.
Catamarans are doomed.
But the most important question is : will a sailboat hull endure the pressure ?

that would depend on several factors primarily angle of attack take it head on or on a high angle quarter much different than broadside . Also depends on build and material.
My current boat would likely survive ( she is morc ) a benehuntalina less likely due to a much lighter build. Steel hull likely survive as well . Now the crew may not fare so well.

Re: Rogue Wave Video - Best I Have Seen
Video doesn't mention using satellite technology to help identify rogue waves, or recent research showing (IIRC) the rapport with wave patterns that converge at 120º angles to form them. The real-life measuring they do showcase from oil platforms does point out how these waves are much more prevalent than previously believed.

Re: Rogue Wave Video - Best I Have Seen
There was a good BBC video on this exact topic, available on You Tube. Since I don't know how to embed it, you can search for it as "BBC2 Horizon freak Wave."

I watched that video last weekend and was thinking of it when I saw this discussion. Here is the link to the video from 2002.
Later,

Re: Rogue Wave Video - Best I Have Seen
The example of the fate of the recovered lifeboat of the ms Muenchen is somewhat comforting.It shows that a vessel of the size we putter about in will be thrown about by these kind of waves rather that demolished. So, as far as hull integrity goes we likely fare better that the "big" boats.
In addition, commercial traffic tends not to slow down when the weather pipes up.
You will loose the rig but may stay afloat.A hardhat may be a useful attribute though.

And why would you think catamarans are doomed? They have no keel and in my case, 4 permanent foam filled enclosed flotation chambers to make them unsinkable.
