It seems to me that
a) this article has been used on the front page as "Freak wave"
and
b) "Freak wave" is used most often in the journals
so is there some reason why this was moved from Freak wave to Rogue wave??
I propose putting it back to the original name back?
If not, then it should be copy and pasted back to the original article and moved properly to preserve the edit history.

Examples of Rogue waves
I think that examples of near shore "rogue waves" could be inappropriately construed as open ocean rogue wave examples. The probability extremely large, near-shore waves is bathymetry dependent. The existence of exceedingly large waves near shore isn't questioned by the scientific establishment. The existence of open ocean rogue waves is governed by different differential equations. The frequency of open ocean rogue waves is still questioned by scientists. —Preceding unsigned comment added by 75.170.41.119 (talk) 09:36, 14 February 2009 (UTC)
Rogue wave in Korea
It seems that on May 5th, 2008 there was a rogue wave occurrence in South Korea, resulting initially in nine people confirmed dead and around 15 missing. FFLaguna (talk) 16:26, 6 May 2008 (UTC)
Drauper event
Ocean Drauper sank on February 15th, 1982 as far as I know. Can somebody confirm this.
- The mobile offshore drilling platform Ocean Ranger sank on 15th February, 1982. The Draupner oil rig was around to be struck by the new year's day wave which all sources agree occurred on 1st January 1995. I think you are confusing the two. Benea (talk) 10:03, 29 May 2008 (UTC)
Merge Sneaker wave into Rogue wave

"Perfect Storm" reference
According to the commentaries on the DVD, the final wave was simply a large storm wave possibly caused by the collision of two other waves and exaggerated for dramatic effect. However, earlier in the movie, a rogue wave was encountered while fishing on relatively calm seas. Amschmid (talk) 01:35, 1 September 2008 (UTC)
Hundred year wave
I removed hundred year wave (which was in bold) from the first sentence, since it is just a statistical measure (a wave with a height which has a probability of exceedance of once per 100 years, on average) and not necessarily a rogue wave (higher than twice the significant wave height of the sea state). Most often, 100-year waves are design waves (since there are no wave records for hundreds of years anywhere), which are computed using linear wave statistics (no rogue waves). Although rogue waves have been measured of a height near the 100-year design wave -- for the offshore structure where they were measured -- this does not imply the two concepts are related.
Despite hundred year wave being a redirect to this article (by lack of a page on wave statistics, or wave forces in structure design), it should not be confused with rogue wave. -- Crowsnest (talk) 22:00, 8 September 2008 (UTC)
- Interesting; thanks for catching that. I agree that "hundred year wave" would be best discussed in an article on wave statistics, based on your explanation. But since nobody's written that article yet, I'm in favor of editing Hundred year wave into an actual article; if need be, it can be merged into another article when the time comes. I can start on that later tonight-- I've found a few sources on Google Book Search-- but since all my knowledge on this topic was compiled in the last five minutes, I fear my contribution will be the stubbiest of stubs. Whatever expertise you have would be a great help. Also, I've found at least one source which equates "hundred year wave" with "freak wave", so there probably should be a note of clarification in the "rogue wave" article. --Fullobeans (talk) 23:55, 8 September 2008 (UTC)
- Looks a good approach to me. Books which should contain something on this are (by head): Goda, Design of maritime structures; and Holthuijsen (2007?). Further there should be quite some information in the Shore protection manual of the US Corps of Engineers (free downloads available online). I have to stop now, but will look on it in one or two days. It would be great if you can make a start on this. -- Crowsnest (talk) 00:17, 9 September 2008 (UTC)
- And a start has been made. It's not much, but it's better than a redirect. I'd look into the references you suggested, but I'm afraid I'm in a bit over my head; so, rather than continuing to edit the article, I'll start working on a time machine so I can go back and tell my sixteen-year-old self to pay attention in physics class. --Fullobeans (talk) 06:16, 9 September 2008 (UTC)

Excellent source from Norway. FX (talk) 13:03, 1 November 2008 (UTC)
- I agree. And from well-known experts in the field. It already appears twice in the external references. -- Crowsnest (talk) 17:59, 1 November 2008 (UTC)
But not used a source? FX (talk) 23:03, 2 November 2008 (UTC)

Historical doubt of Rogue Waves
This article should mention in the history section how no one believed in rogue waves until someone caught one on a camera on an oil platform only a few years ago. Up until at least the late 1990s no one believed in these waves. —Preceding unsigned comment added by 138.88.149.130 (talk) 23:39, 19 December 2008 (UTC)
I saw one in Cuba 1959
172.129.15.180 (talk) 02:00, 18 February 2009 (UTC) *** 1959 I was off Cuba on a Destroyer when a Rogue wave hit our ship. It was a clear ,beautiful day when it came with no warning and washed a Sailor overboard with a power that that gashed his body greatly.He was dead.we were doing asw exercises and a blimp hovered over his body and they reported the sharks came to the blood like a cloud as there were so many of them. The crew on the blimp threw hand grenades to keep the sharks away.I would sure like to hear from any one that also experienced that wave. It must have covered a large area.
Miley Cyrus Fan Page Link?
Removed a bit of vandalism (Miley Cyrus fan page link) from the External Links section. I trust that this is something someone was trying to removed at some point but couldn't figure out how (it was camouflaged as a Template:Commoncat@ tag in the edit page of the first group of External Links. I've added the @ to the tag to prevent a link to the same fan page here in Discussion. Please go to the edit tab of this Discussion page to see what the tag looks like and imagine it without the @ sign. Ultatri (talk) 16:49, 10 March 2009 (UTC)
- The Template:Commoncat was vandalized by a spammer. Thanks for pointing the problem out. I will restore the page to what it was. -- Crowsnest (talk) 16:57, 10 March 2009 (UTC)
Introduction doesn't really make sense
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.
- Therefore? It didn't really provide an explanation as to WHY they're not the biggest waves found at sea. In fact it stated that they were twice as large as the largest waves =/ —Preceding unsigned comment added by 203.59.105.199 (talk) 19:53, 15 April 2009 (UTC)
- It doesn't say they're not the biggest waves found at sea, it says they 'are not necessarily the biggest waves found at sea'. A 10 meter wave in a 5 meter sea state would be a rogue wave, but a 10 meter wave in a 15 meter sea state is nothing out of the ordinary and not a rogue wave. It's not about the raw height of a wave, it's the height of the wave in relation to the average height of the surrounding waves. Benea (talk) 22:09, 15 April 2009 (UTC)
Split of rogue wave list
This should be a no-brainer. The list of rogue wave occurrences is bulky and unnecessary for this article (only the most notable instances should be covered here). The "Reported encounters" section should be split into a List of rogue waves. I'll get to working on it myself eventually, but in the meantime it would be great if someone else could get it started. -RunningOnBrains(talk page) 13:33, 22 July 2009 (UTC)
Photos
I would urge fellow editors to try including a few more legitimate photos of rogue waves. Yes, rogue waves are seldom photographed and when they are, it's hard to get a license free photo. But I think that the photo found here ([1]) at least is available somewhere (like NOAA) and can be added. In fact I think it was in the article 2 years or so ago with proper licensing.--RossF18 (talk) 17:26, 30 September 2009 (UTC)
Lore of rogue waves.
Accounts of rogue waves are well known by seamen. The fact reports were ignored by scientists just shows academic arrogance. Like cold brittleness in steel ships it was not acknowledged until someone wrote an academic paper on the subject. We hit a wave after leaving Sydney on the Tasman Venture in the 80's which was at least three times the SWH which did considerable damage to the foredeck. . At the time it was considered a combination of effects from the Australian coast current, the wind which was about 60 knots after a tropical revolving storm had passed and the effect of the continental shelf. (Bathymetric).
Rogue wave definition
In many articles about rogue waves (freak waves) the definition for these waves is that they are higher than twice the significant wave height. I think there should be a minimum height for rogue waves as well. Now, if the significant wave height is 25cm, then waves higher than 50cm are - per definition - rogue waves. This doesn't seem correct to me. Has any research been done on this part? --FritsKoek (talk) 13:25, 2 December 2010 (UTC)
- The probability (per wave period) of encountering a rogue wave of 50cm height -- at a certain location -- in a Hs=25cm sea is the same as that for encountering a 30m individual wave height in a seas with significant wave height Hs=15m. There is no need for setting a minimum wave heigth (as long as the wavelength is long enough for surface tension to be negligible). Note that rogue wave effects are relative: a 10m rogue wave might have devastating effects on a small yacht, while hardly having an effect on a supertanker. -- Crowsnest (talk) 18:52, 4 December 2010 (UTC)
Texas Tower No. 4 -- January 15, 1961
Examination of the wreckage of the tower, which was overwhelmed and toppled by an Atlantic gale, indicates wave damage at 85 feet above sea level. See L.

Terrigal Tragedy
n the list of 20th-century rogue wave examples someone added -- out of list order, which appears chronological -- an incident in which two people were washed off some rocks by a "huge" wave in Australia in 1939. No estimates are given in the source material for the size of the wave, and what appears "huge" to witnesses on shore isn't necessarily a rogue wave. I'm going to delete the item until more information can be offered supporting the wave as "rogue." — Preceding unsigned comment added by McGehee (talk • contribs) 14:16, 4 June 2012 (UTC)
Error in References
Hello there,
I am new to Wikipedia editing, and tried inserting a reference "Laird1", which somehow screwed up the "Econ1" reference. As far as I can remember, I did not make any changes to "Econ1" and only removed "citation needed" and used the Citation tool to add a citation.
Can someone please help to fix that Econ1 reference?
Thank you. — Preceding unsigned comment added by Hanxue (talk • contribs) 18:10, 25 December 2012 (UTC)
Which kind of wave production has been simulated?
Derek1G (talk) 22:01, 1 July 2013 (UTC) I like the video of the Lego boat in the wave tank, but I can't tell WHICH of the listed mechanisms of rogue wave formation were used in that experiment/video. This should noted in the caption under the video image.
Uncommon?
The article claims rogue waves are uncommon. Of course that word is subjective. But I am not sure I would use that word. For example, a Natl. Geo. article mentioned that scientists found 10 rogue waves in one three week period ( via analysis of satellite imagery.)
