You will recall that the boat in "Perfect Storm" was swollowed by a wave,
that if scale means anything, the wave must have been about 600 feet
high.(This assumes you saw the movie, but did not read the book).
A wave that high would have almost magical qualities. For instance it would
not require teeth in order to swollow it's victims whole. It would have
enough energy to light up the city of Los Angeles for perhaps a whole
minute, just before it covered it up in foam.

Makes you wonder where the human mind gets this kind of silliness.

The misunderstandings about LARGE waves are almost beyond getting under
control.
A few pictures of waves so large that the pictures themselves are legends.

The Mojo crossing the Moro Bay Bar, California.
The freighter in the Bay of Biscay, with a wave that more resembles a 60'
plunging breaker, overtaking the ship from behind.(from the Drag Device
Data Base book).

Then there are the stories. The USS Ramapo, and the wave 112 feet high, as
measured in the cross trees at the bow of the ship. The stories from
magazine articles and books going back at least a thousand years.

Stop and think about it. We have the ability to collect the stories and
pictures, but our ability to put this into perspective is colored by our
individual inexperience and natural tendency to overblow that which almost
everyone of us will never be a witness to.
.
Fact is the ocean is full of freak waves. It's just that most of them are
no problem. And you may live an entire lifetime and never see one that is
worthy of note.
Most professional sailors live an entire lifetime without ever seeing
anything like the picture in the Drag Device Data Base.

On the other hand. The ocean is full of freak surprises and the shallower
the water, the more likely you are to attract the attention of one of them.

More about this some other day.

Hey all,

The biggest wave ever recorded ran up the water's edge almost 1,400 feet
above sea level. The event was an earthquake induced landslide which fell
into the Lituya Bay, Alaska, on July 9, 1958. Boats were carried OVER trees
which were 80 - 90 feet high, and huge trees were entirely stripped from
the soil.

(Another huge wave was caused by the Vaiont Dam failure in Italy on
October, 1964. The wave was caused by a huge landslide into the water
behind the dam. The landslide was almost 2 miles wide, 1/2 mile long, and
hundreds of feet thick, and the resulting wave swept up the river with a
wave about 850 ft high. The water completely washed away a village, and
then rebounded back downriver. When the wave went over the edge of the
concrete dam, it was estimated at 820 ft. high. It should be noted that the
concrete dam suffered no damage (other than a slight spalling at the top)
and is still in use today for energy generation.

Does anyone have a copy of the picture Michael is referring to here?

This is a very interesting subject!

Best all, John

I have nothing to offer but blood, toil, tears, and sweat.
We have before us an ordeal of the most grievous kind. We
have before us many, many months of struggle and
suffering.

You ask, what is our policy? I say it is to wage war by
land, sea, and air. War with all our might and with all
the strength God has given us, and to wage war against
a monstrous tyranny never surpassed in the dark and
lamentable catalogue of human crime. That is our policy.

You ask, what is our aim? I can answer in one word. It is
victory. Victory at all costs -- victory in spite of all
terrors -- victory, however long and hard the road may
be, for without victory there is no survival.

Commons as Prime Minister, May 13, 1940
