Too late.

What if you could muster hundreds of oarsmen and or oarswomen though?

I too picked up on your 'wicked sense of humour', but wanted to give you the satisfaction of believing there were nothing but numbskulls on CF...

Exactly. When weather reporters talk about the wave height in a storm, they're talking about the AVERAGE. Some will be smaller, like the one to port of the boat, and others much bigger, as the starboard one. Rather than calling this a "rogue" wave, maybe a better title would have been something like "this is what average really means ..." It doesn't mean you have to pbe prepared for 10 ft waves -- it means you have to be ready for much bigger. There may not be many of them, but they're there.

Re: Sailboat about to be clobbered by a 100-foot rouge wave (pic)

1998, Sydney to Hobart Yacht race, Film, Part 1,

Video and piccys from a sailor on one of the yachts crossing, It also gives a description of the conditions the Race is run under,

They also have another race leaving on Boxing day, The Melbourne to Hobart Yacht race,

But it goes down the west coast of Tasmania, Hahahahaha,

FYI,

You dont have a good boat here, Dont go out there, Simple,

This must definitely be a bad photoshop job! The OP never called this a rogue wave, but called it a "rouge" wave so must also be colour blind.

The yacht in that boat is/was VC Offshore Stand Aside, and at 12 metres (40') long you can get an appreciation of how big the seas actually were. Stand Aside was the first to issue a mayday in the 1998 Sydney to Hobart after being rolled and dismasted by an estimated 80 foot wave.

The images of the race do not do the sea state any justice. They were truly huge seas and yes, many of the waves had no backs to them.

This isn't meant as aggressive or questioning you -- but there's an "immediacy" about your post. Were you in that race?

Well maybe, I'm not sure what reporters are talking (writing) about,but wave heights are generally reported by oceanographers as significant wave heights , I.E. the average of the highest 1/3 of the waves.

A great example of a horrifyingly large "swell" - but not a "breaking" wave.

A bad bar crossing with "only" 20' breaking waves onto shallow sand is more of a killer than this.

Think of the recent SF race with the S/V "Slow Speed Chase" - it was relatively small breaking waves that killed the crew.

Yes, they were dashed against hard surfaces - but it is incredibly rare for conditions in the open ocean to produce real breaking waves versus just large scary swells with a bit of white water on top...

Yeah, and remember, wave height is measured from the trough to the crest... so a 10 ft wave is more or less 5 ft high from sea level..... right?

My points are 1) don't hear a number like "10 ft waves" and assume there will be no 20' ones out there, and 2) don't count on the media to get technical details right when they are reporting on something specialized, like -- oh, say, sailing.

Just to be a bit pedantic . . . Usually (but not always) the wave heights quoted are the "significant heights", which is the average of the highest 1/3 Waves. This metric was developed way back as the closest to what a human observer says the average wave height is.

The 1 in 1000 waves will be 1.86x bigger than the significant height. You get one of those about every 2-4hours with typical storm wave periods.

2x the significant height is the technical definition for a "rogue".
