Vendee Globe : Cape Leeuwin

Saturday 15th 04:00 UTC situation : the two leaders François Gabart and Armel Le Cléac'h
passed the longitude of SW Australia’s Cape Leeuwin,  the second of the course’s three Great Capes,
34 days 10h and 23 minutes after the departure, so 2 days 2h and 25 min better than 2004 best time

Cape Leeuwin is the most south-westerly mainland point of the Australian Continent, in the state of Western Australia.

In Australia, the Cape is considered the point where the Indian Ocean meets the Southern Ocean.

entitled "Caert van't Landt van d'Eendracht".
This detail shows a section of coastline discovered by the Leeuwin in 1622,
and subsequently referred to by the Dutch as 't Landt van de Leeuwin ("The Land of the Leeuwin")

The Royal Australian Navy's Leeuwin class survey vessel HMAS Leeuwin is named after the cape, which is named after the ship the Leeuwin, a Dutch galleon that charted some of the nearby coastline in 1622.
The south-west corner of Australia was subsequently referred to by the Dutch as 't Landt van de Leeuwin ("The Land of the Leeuwin") for a time, subsequently shortened to "Leeuwin's Land" by the English.
This name Leeuwin still survives in the name of Cape Leeuwin, the most south-westerly point of the Australian mainland, so named by Matthew Flinders a distinguished navigator and cartographer, who was the first to circumnavigate Australia and identify it as a continent in December 1801.

Where the Indian and Southern Oceans meet, stands Cape Leeuwin Lighthouse as a solitary sentinel.

Galešnak (also called Island of Love, Lover's Island, Otok za Zaljubljene) is located in the Pašman channel of the Adriatic, between the islands of Pašman and the town of Turanj on mainland Croatia.

The small heart-shaped island of Galešnjak is featured in this image acquired on 19 March 2010 by ALOS. The 500 m-wide island is situated off the Croatian coast in the Adriatic Sea, between the city of Turanj (visible in white stretching along Croatia’s mainland coast) and the Island of Pasman (bottom left).
Other visible islands include (left to right): Garmenjak (bottom), Mala Bisaga, Vela Bisaga, Ricul and Komornik.

It is one of the worlds few naturally occurring heart-shaped objects.

Chasing Ice movie reveals largest iceberg break-up ever filmed


We’ve already written about photographer James Balog’s documentary film Chasing Ice in the past.
His team spent years shooting time-lapse photographs of glaciers around the world using solar-powered Nikon DSLRs, which allows changes over a long period of time to be seen in just seconds or minutes.

One particular scene in the movie shows an epic event: the largest iceberg breakup ever caught on camera.
Here’s what the team says about the 75-minute event, which is known as ice calving:
Pieces of ice were shooting up out of the ocean 600ft and then falling.

The only way that you can really try to put it into scale with human reference is if you imagine Manhattan, and all of a sudden all of those buildings just start to rumble and quake and peel off and fall over and roll around.
This whole massive city just breaking part in front of your eyes.

Online maps switch to 'Algeciras Bay'


 Bing Maps (Yahoo Maps / Nokia)

From Gibraltar Chronicle

Spain has long referred to the Bay of Gibraltar as the Bahía de Algeciras, much to Gibraltar’s annoyance.


But now, in a move that will spark a furious response here in Gibraltar, Madrid appears to have won influential international support for the Spanish version of the name.

Google Earth view
Note : not any label on Google Maps

Two major online map services, Google Earth and Bing maps, have labelled the Bay of Gibraltar as Bahía de Algeciras in their latest updates.

In a similar development, the latest version of the Encyclopaedia Britannica also refers to the bay as the Bay of Algeciras, even though historical editions named it as Gibraltar Bay.

It is not clear why all three outlets have chosen to opt for the Spanish name, but the decision comes at a time when Spain is pushing hard to exert influence and jurisdiction in Gibraltar waters.

The Spanish Government has long referred to the bay as Bahía de Algeciras, in part because of its assertion that the waters around the Rock are Spanish and not British.

But admiralty charts and nautical maps used worldwide refer to the bay by its English name.

 but 'Bahia of Algeciras' is still there in some international nautical chart (INT 3152 / ES 445A )
see SHOM #7026 (2009)

so the job for the online mapping service leaders is not simple...

The bizarre amphibious vehicle inventor claims is driven by perpetual motion


MSV Explorer semi submersible delivery mechanism
Inventor builds amphibious vehicle that will be powered 'by self-sustaining energy' to prove that perpetual motion IS possible
Chris Garner has released prototype of his first amphibious vehicle

From DailyMail

Chris Garner has released prototype of his first amphibious vehicle
He claims it is powered by what describes 'Gyro Generator' technology that he says will revolutionise the way we travel

He came up with the idea for his range of personal marines after a close encounter with a large shark.
But now concept designer Chris Garner is also preparing for coming face-to-face with predators on land - with his first attempt at an amphibious craft.
But he claims that is not the remarkable aspect of his new Explorer MSV.
Mr Garner claims to have found a solution to the age-old puzzle of perpetual motion and is now poised to go public with his scientific breakthrough.

Amphibian ambition: The vessel works both in the water and on land

He believes his new 'Gyro Generator' technology will revolutionise the way in which we travel and enable electric vehicles to run indefinitely with no requirement to stop and recharge at regular intervals.
His company's website describes the current submarine version 'as an electrically powered, dual joystick controlled, dry cockpit surface water craft, meticulously designed and engineered to place two observers within an acrylic cockpit below the surface of the ocean at a constant 1.2m, with a topside principal pilot seat.'


 
The Discovery Channel Canada recently aired a documentary featuring a tracked, amphibious prototype of the Explorer and is keeping a close eye on recent developments.
They are also hoping to return and showcase Garner's latest model using what the inventor prefers to describe as 'self-sustaining energy'.
The technology itself will be put to the test in the next two weeks by academics from the University of Plymouth.
Then we can decide if his theories hold water.
