Sydney Hobart : Wild Oats XI unveils secret weapons


Sydney-Hobart in 2011

From BrisbaneTimes

A new sail the size of two tennis courts has been unveiled as Wild Oats XI's secret weapon as she tries to win Sydney to Hobart yacht race line honours for a sixth time.
High-tech new keel "winglets" and a retractable bow centreboard have also recently been added to the 30-metre super maxi in a bid to make her much faster in light winds.
Wild Oats XI is the overwhelming favourite for the 2012 blue water classic and has shown superb form in all the lead-up races - including setting a record in November's Cabbage Tree Island 180-nautical mile race.
But she will face tough competition for line honours in the form of Ragamuffin Loyal - which pipped Wild Oats XI to victory in the 2011 Sydney-Hobart by just over three minutes - and the highly-fancied Wild Thing.

"We're hurting from last year's result," Wild Oats XI sail trimmer Josh Whittaker said. "The new modifications are worth seconds to us every mile.
"Last year, we lost by three minutes and, with these modifications, we could have been 12 minutes faster."

 'XI, WILD OATS XI, Sail No: 10001, Owner: Mark Richards,

The new headsail measures 535 square metres and was ordered by Wild Oats XI owner Bob Oatley, 84, who said last year's defeat "hurt like hell".

His skipper Mark Richards described the new sail as like "replacing a rifle with a cannon" and insisted Wild Oats XI could complete the 628-nautical mile run down to Hobart in less than 24 hours, given the right weather conditions.
That would break the yacht's own race record of just over one day and 18 hours, which was set on the way to victory in 2005.

"We can't control the weather but we can go into the race knowing that we can do no more when it comes to having the fastest possible yacht," Richards said. "And that is the case this year."
The new winglets operate on a similar principle to the wing tips on modern passenger aircraft and are designed to reduce drag.
They were produced with help from Boeing and tested over two weeks in a hydrofoil tank in Tasmania.

Ragamuffin Loyal competed under the name Investec Loyal in 2011 and, this year, is skippered by 85-year-old veteran Syd Fischer.
The super maxi, which suffered rigging damage last Wednesday, will have her mast put back in on Tuesday and will have training runs on Thursday and Friday.
The fleet dropped a boat on Monday following the withdrawal of the 52-foot Dodo.

The end of the map : why the World looks the way it does



On the Maps by Simon Gardfield
Cartography enthusiasts rejoice: the bestselling author of Just My Type reveals the fascinating relationship between man and map.

From WSJ

Apple Maps stands at the end of a long line of cartographic catastrophes.
Say goodbye to the Mountains of Kong and New South Greenland—the enchanting era of geographic gaffes is coming to a close.

It's not often that maps make headlines, but they've been doing so with some regularity lately.
Last week, tens of millions of iPhone users found that they could suddenly leave their homes again without getting either lost or cross.
This was because Google finally released an app containing its own (fairly brilliant) mapping system. Google Maps had been sorely missed for several months, ever since Apple  booted it in favor of the company's own inadequate alternative—a cartographic dud blamed for everything from deleting Shakespeare's birthplace to stranding Australian travelers in a desolate national park 43 miles away from their actual destination.
As one Twitter wag declared: "I wouldn't trade my Apple Maps for all the tea in Cuba."

There was one potential bright spot, though: Among the many mistakes found in Apple Maps was a rather elegant solution to the continuing dispute between Japan and China over the Senkaku islands. Japan controls them; China claims them.
Apple Maps, when released, simply duplicated the islands, with two sets shown side-by-side—one for Japan, one for China.
Win-win. (At least until the software update.)
Call it diplomacy by digital dunderheadedness.

As some may recall, it was not so long ago that we got around by using maps that folded. Occasionally, if we wanted a truly global picture of our place in the world, we would pull shoulder-dislocating atlases from shelves.
The world was bigger back then.
Experience and cheaper travel have rendered it small, but nothing has shrunk the world more than digital mapping.

In medieval Christian Europe, Jerusalem was the center of the world, the ultimate end of a religious pilgrimage.
If we lived in China, that focal point was Youzhou.
Later, in the days of European empire, it might be Britain or France.
Today, by contrast, each of us now stands as an individual at the center of our own map worlds.
On our computers and phones, we plot a route not from A to B but from ourselves ("Allow current location") to anywhere of our choosing.
Technology has enabled us to forget all about way-finding and geography.
This is some change, and some loss.

Maps have always related and realigned our history; increasingly, we're ceding control of that history to the cold precision of the computer.
With this comes great responsibility.
Leading mapmakers used to be scattered around the world, all lending their distinctive talents and interpretations.
These days by far the most influential are concentrated in one place—Mountain View, Calif., home of the Googleplex.

There is something disappointing about the austere potential perfection of the new maps.
The satellites above us have seen all there is to see of the world; technically, they have mapped it all. But satellites know nothing of the beauty of hand-drawn maps, with their Spanish galleons and sea monsters, and they cannot comprehend wanderlust and the desire for discovery.
Today we can locate the smallest hamlet in sub-Saharan Africa or the Yukon, but can we claim that we know them any better?
Do the irregular and unpredictable fancies of the older maps more accurately reflect the strangeness of the world?

The uncertainty that was once an unavoidable part or our relationship with maps has been replaced by a false sense of Wi-Fi-enabled omnipotence.
Digital maps are the enemies of wonder.
They suppress our urge to experiment and (usually) steer us from error—but what could be more irrepressibly human than those very things?


There is something valuable about getting lost occasionally, even in our pixilated, endlessly interconnected world.

Among cartographic misfirings, the disaster of Apple Maps is rather minor, and may even have resulted in some happy accidents—in the same way that Christopher Columbus discovered America when he was aiming for somewhere more eastern and exotic.
The history of cartography is nothing if not a catalog of hit-and-miss, a combination of good fortune and misdirection.

The story starts at the Great Library of Alexandria around 330 B.C., the place where the study of geography really began.
Its first scholars constructed an important proto-map of the world, based largely on the writings of the Greek historian Herodotus.
His nine-volume "Researches" had been completed a century and a half earlier, but his description of the rise and fall of the Persian Empire and the Greco-Persian wars remained the most detailed source of information on the shape of the known world.

These early scholars got a lot right—and inevitably a fair bit wrong.
The map they constructed depicted the world as round, or at least roundish, which by the fourth century B.C. was commonly accepted (dismissing the Homeric view that if you sailed long enough you would eventually run out of sea and fall off the end).

 Eratosthenes of Cyrene (in modern-day Libya) was one of the first scholars to marshal the new geographical knowledge into the art of cartography.
His world map was drawn in about 194 B.C.E., and the Victorian-era reconstruction of it (the original has long vanished) resembles a dinosaur skull.

Eratosthenes of Cyrene (in modern-day Libya) was one of the first scholars to marshal the new geographical knowledge into the art of cartography, making fullest use of the Library of Alexandria's scrolls, the accounts of those who had swept through Europe and Persia in the previous century, and the pertaining views of the leading contemporary historians and astronomers.

His world map was drawn in about 194 B.C., and the shape of the Victorian-era reconstruction of it (the original vanished long ago) resembles nothing so much as a dinosaur skull.
There are three recognizable continents—Europe to the northeast, Africa (described as Libya and Arabia) beneath it and Asia occupying the eastern half of the map.
The huge northern section of Asia is called Scythia, an area we would now regard as encompassing Eastern Europe, the Ukraine and southern Russia.

The map is sparse but sophisticated, and noteworthy for its early use of parallels and meridians in a grid system (with, bizarre as it seems to us now, the island of Rhodes—then a major trading post—at the center of everything).
The inhabited world (something the Romans would later call "the civilized world") was believed to occupy about one-third of the northern hemisphere and was wholly contained within it.

The northernmost point, represented by the island of Thule (which may have been Shetland or Iceland), was the last outpost before the world became unbearably cold; the most southerly tip, labeled enticingly as Cinnamon Country (corresponding to Ethiopia/Somaliland) was the point beyond which the heat would burn your flesh.
There are no poles, and the three continents appear purposely huddled together, as if the huge encroaching oceans and the vast areas of the unknown world are joining forces against them.
There is no New World, of course, no China, and only a small section of Russia.

In the second century, the work of Eratosthenes would be one of the templates used to produce what is traditionally regarded as the bridge between the ancient and the modern world: Claudius Ptolemy's "Geographia."
This contained a vast list of names of cities and other locations, each with a coordinate, and if the maps in a modern-day atlas were described rather than drawn, they would look something like Ptolemy's work, a laborious and exhausting undertaking based on a simple grid system.
He provided detailed descriptions for the construction of not just a world map but 26 smaller areas.

Claudius Ptolemy's Geographia contained a vast list of names of cities and other locations, each with a coordinate.
However, Ptolemy was prone to the biggest cartographic vice: when lacking precise information, he made things up.

As one would expect, Ptolemy still held a skewed vision of the world, with distortions of Africa and India, and the Mediterranean much too wide.
But his projection of the shape of the world is still something we would recognize today, and the placement of cities and countries within the Greco-Roman empire is highly accurate.
He gives due credit to another key source, Marinus of Tyre, whose map was the first to include both China and the Antarctic.

But Ptolemy was prone to the biggest and most contagious cartographic vice: Lacking precise information, he just made things up.
Like nature itself, mapmakers have always abhorred a vacuum.
White space on a map reveals ignorance, and for some this has always been too much to bear.
Ptolemy could not resist filling blanks on his maps with theoretical conceptions, something that plagues exploration to this day.
The Indian Ocean was displayed as a large sea surrounded by land, while many of his measurements of longitude (something that was very hard to measure accurately until John Harrison's timepiece won a famous competition in the 18th century) were way off beam.
The biggest miscalculation of all, the longitudinal position of the Far East, would eventually suggest to Columbus that Japan could be reached by sailing West from Europe.
But Ptolemy was at least attempting to map on scientific principles.

Not so the wonderful mappae mundi, a collection of large conceptions of the world that filled our imaginations from the 11th century to the Renaissance.
These maps, which primarily adorned the world's churches and other places of power and learning, succeeded in returning mapping to the dark ages, getting much wrong and gleefully so.
Their goal was not navigation and accurate knowledge but rather religious instruction.
The maps contained places we seldom see on modern charts these days—Paradise, for instance, and fiery Hell—and the sort of bestiary and mythical imagery one might expect to find in Tolkien's Middle-earth.
We can marvel at the mythical bison-like Bonacon, for example, spreading his acidic bodily waste over Turkey, and the Sciapod, a people whose enormously swollen feet were said to make fine sun-shields.

Gerardus Mercator famous projection map in 1569 forms the basis of schoolroom teaching and Google Maps.
The projection provided a solution to the puzzle of how to represent the curved surface of the globe on a flat chart.

The Renaissance and the golden age of exploration brought forth a stricter regime and hot-off-the-deck maps from Portuguese and Spanish explorers.
Cumulatively, these resulted in the famous projection map of Gerardus Mercator in 1569, a plan of the world that still forms the basis of schoolroom teaching and Google Maps.
The projection provided a solution to a puzzle that had troubled mapmakers since the world was recognized as a sphere: How does one represent the curved surface of the globe on a flat chart? Mercator's solution remains a boon to sailors to this day, even as it massively distorts the relative sizes of land masses such as Africa and Greenland.

For more than two centuries, California was not attached to the West Coast mainland but was thought to be an island, drifting free in the Pacific.

The catalog of cartographic inaccuracies goes on.
Those living in California may be curious to know that for more than two centuries their homeland was not attached to the West Coast mainland but was thought to be an island, drifting free in the Pacific.
This wasn't a radical act of political will, nor a single mistake (a slip of an engraver's hand, perhaps), but a sustained act of misjudgment.
Stranger still, the error continued to appear on maps long after navigators had tried to sail entirely around it and—with what must have been a sense of utter bafflement—failed.
Between its first appearance on a Spanish map in 1622 and its fond farewell in a Japanese publication of 1865, California appeared insular on at least 249 separate maps.
Whom should we blame for this misjudgment?
Step forward one Antonio de la Acensión, a Carmelite friar who noted the "island" in his journal after a sailing trip in 1602-03.

 The Mountains of Kong, shown in Africa on an 1839 American atlas, were 'discovered' by English cartographer James Rennell in 1798.
Rennell based his map showing the fictional range on an erroneous account from a Scottish explorer.
It persisted on maps for almost a century—until it was discovered not to exist.
(courtesy of David Rumsey collection

But my favorite cartographic error is the Mountains of Kong, a range that supposedly stretched like a belt from the west coast of Africa through half the continent.
It featured on world maps and atlases for almost the entire 19th century.
The mountains were first sketched in 1798 by the highly regarded English cartographer James Rennell, a man already famous for mapping large parts of India.
The problem was, he had relied on erroneous reports from harried explorers and his own imagined distant sightings.
The Mountains of Kong didn't actually exist, but like an unreliable Wikipedia entry that appears in a million college essays, the range was reproduced on maps by cartographers who should have known better.
It was almost a century before an enterprising Frenchman actually traveled to the site in 1889 and found that there were hardly even any hills there.
As late as 1890, the Mountains of Kong still featured in a Rand McNally map of Africa.

And then there was the case of Benjamin Morrell, who had drifted around the southern hemisphere between 1822 and 1831 in search of treasure, seals, wealth and fame.
Having found little of the first three, he apparently thought it amusing to invent a few islands en route.
The published accounts of his travels were so popular that his findings—including Morrell Island (near Hawaii) and New South Greenland (near Antarctica)—were entered on naval charts and world atlases.


The map here, from explorer Ernest Shackleton's account of his 1914-17 journey to the Antarctic, notes the purported location of 'New South Greenland' (highlighted).
Described in 1823 by Capt. Benjamin Morrell, the island could not be located.
(Project Gutenberg Australia)

In 1875, a British naval captain named Sir Frederick Evans finally began crossing some of these phantoms out, removing no fewer than 123 fake islands from the British Admiralty Charts.
It wasn't until Ernest Shackleton's 1914-17 Endurance expedition, however, that the matter of New South Greenland was put to rest.
Shackleton found that the spot was in fact deep sea, with soundings up to 1,900 fathoms.
Morrell Island came off maps not long after that.

Benjamin Morrell, who had drifted around the southern hemisphere between 1822 and 1831 in search of treasure and fame, thought it amusing to invent a few islands en route.
It wasn't until shortly after Ernest Shackleton's 1914-16 Endurance expedition that Morrell Island came off maps.
But perhaps we shouldn't be too hard on the early mapmakers, these pioneers of error.
I would argue that Morrell and his misguided fellow adventurers made the world a more exciting and romantic place in which to live.
Haven't we lost something important as mapmaking has become a science of logarithms and apps and precisely calibrated directions?

Though those who gratefully downloaded Google Maps on their smartphones last week might disagree, there is something valuable about getting lost occasionally, even in our pixilated, endlessly interconnected world.
Children of the current generation will be poorer for it if they never get to linger over a vast paper map and then try in vain to fold it back into its original shape.
They will miss discovering that the world on a map is nothing if not an invitation to dream.

NOAA warns large ships to avoid sanctuary

>>> geolocalization with the Marine GeoGarage <<<

"...here there is no place to land on from out of the grey water. For without are sharp crags, and round them the wave roars surging, and sheer the smooth rock rises, and the sea is deep thereby, so that in no wise may I find firm foothold and escape my bane, for as I fain would go ashore, the great wave may haply snatch and dash me on the jagged rock - and a wretched endeavour that would be."
- Homer, The Odyssey


The National Oceanic and Atmospheric Administration is asking ships of 400 gross tons or greater to stay farther away voluntarily from part of the Olympic Coast National Marine Sanctuary when traveling along the coast to protect the area from possible oil spills.

The “area to be avoided,” known as an ATBA, extends as far as 25 nautical miles (28.7 miles) west of the coast from Tatoosh Island at the north to Pacific Beach State Park to the south.

It was developed by NOAA and the Coast Guard when the sanctuary — which includes 2,408 square nautical miles (2,771 square miles) of marine waters off the Olympic Peninsula Pacific Coast — was established in 1994 to reduce the risk of a shipwreck and resulting pollution to the sanctuary.

The ATBA has been marked on nautical charts since then, and vessels greater than 1,600 gross tons were asked to avoid the area.

Since Dec. 1, smaller ships also have been asked to find another route to travel south in the Pacific Ocean from the mouth of the Strait of Juan de Fuca.

“The consequences of an oil spill can be devastating to the environment and regional economy, and the maritime industry recognizes that supporting such precautions is good for their business as well as the environment,” said Carol Bernthal, superintendent of NOAA’s Olympic Coast National Marine Sanctuary, which is based in Port Angeles.

In the years since the ATBA was adopted, 99 percent of the nearly 9,000 ships that pass through the region annually have complied with the boundaries, said George Galasso, assistant sanctuary superintendent.

Ships greater than 400 gross tons are required to prepare oil spill response plans because of the large amounts of fuel they carry, Galasso said.
Most of that oil is for their own use, such as fuel oil for propulsion, but is enough to damage the sanctuary in the event of a wreck.

According to the new rules, the voluntary avoidance area does not apply to fishing vessels, research vessels and naval ships that are taking part in activities allowed in the area.

The International Maritime Organization adopted the revised ATBA for charts used by the international shipping industry, while the Coast Guard is working with NOAA to have these changes added to nautical charts and included in the U.S. Coast Pilot.

Compliance with the ATBA will be monitored by the sanctuary and the U.S. and Canadian coast guards, which work together to manage the shipping lanes in the Strait of Juan de Fuca, which is dissected by the international border.

The sanctuary, in cooperation with the U.S. Coast Guard, will continue an education and outreach campaign to the maritime industry, distributing informational charts and informing ship owners when their vessels enter the area, Galasso said.

Lying in fifth place in the Vendee Globe Bernard Stamm has stopped Cheminees Poujoulat in the Auckland Islands to the south of New Zealand in order to effect repairs to his hydro generators.
He then intends to continue.
Stamm stopped on the sheltered side of island late afternoon yesterday (UTC).
After struggling to find a protected spot, Stamm is ended up moored in Sandy Bay, on the side of south of Enderby Island, to the northeast of the main Auckland island. (Vendee Globe info)

This has offered him protection from the 25 knot northwest wind.
He has reported sightings of whales and sea lions.
The islands represented the last possibility of shelter before Cape Horn, 4,000 miles away.

Samuel Enderby & Sons was one of the most prominent English sealing and whaling firms, active in both the Arctic and Southern Oceans. 
Also in 1830, Charles became a founding member of the Royal Geographical Society (RGS).
Charles encouraged masters of Enderby vessels to report geographical discoveries and had notable successes with John Biscoe and John Balleny, who between them discovered Enderby Land, Graham Land, the Balleny Islands and the Sabrina Coast.
Another Enderby captain, Abraham Bristow, discovered the Auckland Islands in 1806, naming one of the islands Enderby Island.

Shipwrecks have always been an unfortunate part of New Zealand’s maritime heritage.
For the castaways marooned on offshore islands, particularly in the subantarctic, life was a very grim prospect.
Apart from the trauma of shipwreck, once the basics of food, shelter and fire had been secured, and discipline and social organisation established, there was the dreadful prospect that castaways might never be rescued.
New Zealand’s subantarctic island groups lie in a semicircle to the south and south-east, and many ships that strayed into their path have been wrecked.
The islands lie on the Great Circle Route, which was used by sailing ships leaving the southern Australasian ports for Europe.
The ships dropped down into the Southern Ocean to take advantage of the prevailing westerly winds, which blew uninterrupted on the way around Cape Horn.

The figurehead can now be viewed at the Canterbury Museum in Christchurch, New Zealand.
The reef where she ran aground is called "Derry Castle Reef" and the bay this reef is in, is called "Bones Bay".

The Derry Castle, on a voyage from Geelong to Falmouth, was wrecked on this rocky northern coast of Enderby Island on 20 March 1887.
Fifteen drowned, but eight reached Enderby Island and eventually built a punt, which they sailed to Auckland Island and its provision depot. The survivors were rescued in June. (see link)

This cover is from the 1880 edition of Wrecked on a reef (or Twenty months on the Auckland Islands)
which was republished in New Zealand in 2003.
FranƧois-Erdouard Raynal’s epic account of the wreck of the Grafton and the five castaways’ survival on Auckland Island
helped make castaway stories important in maritime folklore.
Raynal’s account, first published in French in 1870 and in English in 1874, was used by Jules Verne for his book Mysterious island.
