CQR anchors

[guernseyman]

Thank you Mirelle for that interesting snippet.
And Angus. I should have guessed he'd be in the Wikipedia. Isn't it great?

This story is not relevant to CQR's but it is about another great fluid dynamicist: Professor Sir James Lighthill, also a Trinity, Cambridge man.

He married a Sark lady and spent many holidays there. With an increasing knowledge of the tides there, he theorised that if you entered the water, swimming, at a certain point at a certain time, the tidal currents would sweep you completely round Sark, hardly swimming a stroke.

He put his theory to the test - and it worked. Thus for many years he repeated his unique method of circumnavigating the island.

Until a few year's ago, he tried for the last time, had a heart attack and died in the water. At least that is what they worked out had happened after fishing his body out of the water.

I knew him. not through the local connection, but because he chaired the steering committee of a research unit I worked in .

SPADE is an acronym in French by the way and pronounced "spahd".

Perhaps Alain can tell us if the English meaning was a deliberate coincidence (like that for a good non committal phrase?) when the word is read as English.

Perfectly right..

S.P.A.D.E. is the French Acronym for: "S"ociété de "P"roduction d’"A"ccastillage et "D"ivers "E"quipement

This means . “Company Manufacturing Boat and Miscellaneous Equipment”

I have to admit that the English meaning was not a coincidence /forums/images/graemlins/laugh.gif It was made on purpose.. /forums/images/graemlins/tongue.gif

"Due to the time required and the large number of anchors to be tested, only one test per anchor was made."

So anchoring in bad ground (soft mud) should always work the first time?
Some test.
There have been much more comprehensive and independent tests over the years.

They can be found on the net.
