Coast a 'graveyard' of lost ships

More than 2,000 Delmarva wrecks featured on new map

For beachcombers, Delmarva's waterways are delivering constant reminders of a bygone era.

The artifacts that have washed ashore from long-forgotten shipwrecks -- everything from button covers to Buddha statues -- hold both historical and mythic value to collectors like Bill Winkler of Ocean View.

"The history is more important than a piece of pottery or glass bottles," he said.
"Literally tons, as in 2,000 pounds per ton plural, have been collected over the past 100 years."

Although not all the items can easily be traced to a particular wreck, given the daunting number of ships lost offshore since the days of the first 17th century settlers, Winkler said they all tell a story.

Now, at least part of the region's sunken history is being told through a map of the Shipwrecks of Delmarva commissioned by National Geographic.

Don Shomette, who's written volumes of literature about nautical history, was tasked with culling the 7,000 known shipwrecks to the 2,200 featured on the map.
Based on predictive modeling, he said between 10,000-12,000 wrecks are believed to lie on or beneath the sea floor.

The region's waterways rival the Outer Banks of North Carolina as the "graveyard of lost ships," he said.
"It was an embarrassment of riches," he said.
"There were so many important sites, and a number of them couldn't be included."

The process of selecting the sites to be included took more than a year itself, Shomette said.
He and cartographer Robert Pratt made the selections based on cultural and historical relevance, as well as diversity. Revolutionary War-era privateers exist alongside 1850s paddle steamers, Navy submarines and modern pleasure cruisers.

"We didn't want to put every work boat and every barge -- even though some of them are enormous in size -- in there," Shomette said.

Assembling the list meant pulling from his life's work: decades spent poring over government documents, letters and old newspapers, determining the location and details of wrecks across the region.

Just like Winkler, Shomette said the importance lies in what the wrecks have to tell him.
"Ships at sea have their own laws, customs and ways separate from land society," he said.
And Shomette said most mariners, whose "roots were at sea," left little or no record in the wider world.

Conversely, he said shipwrecks also serve as time capsules of what society was like at the time they were lost.
"A ship is unique," Shomette said. "A ship is a container of the society that built it, sailed it, fought on it and died in it."

Beth Gott, an interpreter at the Zwaanendael Museum in Lewes, said the site's shipwreck displays -- of the Dutch
H.M.S. De Braak, which was captured by the British and capsized off Lewes in 1798, and a wreck discovered during beach replenishment dredging near Roosevelt Inlet in 2004 -- are among the most popular.

"People are fascinated by the story of what happened to it and all the mysteries behind it," she said.

Although an estimated 40,000 artifacts were collected by researchers at the wreck site, Gott said people are still finding items believed to have come from the ship.

"A gentleman just walked in yesterday," she said.
"He found a piece of brown stoneware; he was so excited."

Aside from a few news articles which crop up from time to time, Winkler said most people are unaware of financial and historical wealth beneath the waves.

"The people who know where these shipwrecks are don't really blab about it," he said.
"If I found gold bullion over here, I wouldn't either."

NOAA satellites aid in the rescue of 295 people in 2010


Cospas-Sarsat Programme - The First Generation

From NOAA

In 2010, NOAA satellites were critical in the rescues of 295 people from life-threatening situations throughout the United States and its surrounding waters.
The satellites picked up distress signals from emergency beacons carried by downed pilots, shipwrecked boaters and stranded hikers, and relayed the information about their location to first responders on the ground.



 

NOAA’s polar-orbiting and geostationary satellites, along with Russia’s COSPAS spacecraft, are part of the international Search and Rescue Satellite Aided Tracking system, called COSPAS-SARSAT.
This system uses a network of satellites to quickly detect and locate distress signals from emergency beacons onboard aircraft and boats, and from smaller, handheld personal locator beacons called PLBs.

Alaska had the most people rescued last year with 77, followed by Florida with 37, and West Virginia with 17, who were aboard a downed Army Reserve helicopter.

“With each rescue, the
COSPAS-SARSAT system performs the way it was intended — as a real, life-saving network,” said Chris O’Connors, program manager for NOAA SARSAT.

When a NOAA satellite finds the location of a distress signal within the United States or its surrounding waters, the information is relayed to the
SARSAT Mission Control Center based at NOAA’s Satellite Operations Facility in Suitland, Md.
From there, the information is quickly sent to a
Rescue Coordination Center, operated by either the U.S. Air Force, for land rescues, or the U.S. Coast Guard, for water rescues.

Now in its 29th year, COSPAS-SARSAT has been credited with supporting more than 28,000 rescues worldwide, including more than 6,500 in the United States and its surrounding waters.


2010 SARSAT Rescue Highlights

Of the 295 saves last year, 180 people were rescued from the water, 43 from aviation incidents, and 72 in land situations where they used their PLBs.

  • In a joint U.S. Coast Guard-Navy operation, a man was rescued from his capsized boat, 250 miles off of Cape Hatteras, N.C.
  • Although not included in the 295 count, Abby Sunderland, a California teen attempting to set a new record for youngest solo sail around the world, was rescued when she activated her emergency beacons. A storm took her mast — which also left her satellite phone inoperable — and left her boat adrift in the southern Indian Ocean over 2,000 miles from shore. Hers is among the non-U.S. rescues in 2010; those numbers will officially be released later this year.

By law, owners of emergency beacons are required to register them with NOAA at: www.beaconregistration.noaa.gov
That registration information often helps provide better or faster assistance to people in distress. It may also provide information about the location of the emergency situation, how many people need assistance, what type of help may be needed and other ways to contact the owner.

AC45 wing-sailed catamaran under sail in Auckland



From AmericaCup

New Cat Class Centerpiece of 2011-2012 America’s Cup World Series

Auckland’s Viaduct Harbour (position on the Marine GeoGarage) showcased a glimpse into the future of the America’s Cup with the debut of the wing-sailed AC45 catamaran.
The forerunner to the next generation of America’s Cup boats, the AC45 made its maiden voyage, the first of many sea trials planned over the coming weeks.

“Thanks to the efficiency of the New Zealand boat building industry and a huge effort by our team, the first AC45 is now ready for sea trials just a mere four months after this exciting new multihull class was first conceptualized,” said Tim Smyth, co-construction manager for Core Builders Composites of Warkworth, New Zealand.

The AC45 will be the centerpiece of the 2011-2012 America’s Cup World Series, which will start mid-2011.
The high-tech carbon fibre catamaran is the first in a fleet of the new 45-foot one-designs that will be tested by America’s Cup teams before racing on the America’s Cup World Series circuit.

The AC45 is an essential element of the vision for the 34th America’s Cup, which will feature 72-foot catamarans raced on San Francisco Bay in 2013.
Focused on creating more on-the-water excitement for both the teams and the fans, the AC45 is designed for both speed and close racing.
While capable of closing speeds of up to 30 knots, the AC45 was designed to remain nimble enough to handle the tight race courses planned by America’s Cup Race Management (ACRM).

“The biggest challenge with multihulls is learning how much to anticipate.
With the AC45 being a big, powerful multihull capable of tripling the wind speed, your reactions and skills are accelerated.
It’s all about being ahead of the cycle,” said Oracle Racing skipper James Spithill.
“I think the AC45 will enable all teams to advance to hard-core race mentality very quickly.”

The AC45 was designed by the Oracle Racing design and engineering team, which developed the catamaran on behalf of the America’s Cup community.
At task was designing a boat that would not only meet the racing criteria, but could also fit inside a 40-foot container, which is the shipping vessel for the America’s Cup World Series.

“The boat was designed for all-around performance so it can be sailed in wide range of conditions, and that means the next America's Cup will see races start on time,” said Ian Burns, Oracle Racing design coordinator.
“Plus it’s a regatta boat, meant for lots of racing, so quick assembly and disassembly was a must to accommodate an active competition schedule.”

The AC45 had to be robust enough to sail through a wide wind range, from 5 to 30 knots, as well as survive in the event of collisions, which are foreseen as teams learn to adapt to multihull closing speeds.

Utilizing the same technology used in the aerospace industry, the hulls are built in carbon epoxy with honeycomb cores, making them extremely stiff and light structures.
The sandwich construction involves two carbon skins less than 1mm thick laminated over an ultra-light honeycomb core.

“The new America’s Cup is for those who are hungry for a challenge and the AC45 is really a fresh take on the multihull,” said Vincenzo Onorato, President, Mascalzone Latino.

“We plan to run tight race courses that will force boats to engage with each other, creating really close racing situations. Multihulls are very fast boats and will therefore reach the course boundaries sooner, so races will become a true test of skill and strategy, not just speed,” said Iain Murray, CEO, America’s Cup Race Management and Regatta Director.
“The AC45 will fast-track teams to state-of-the-art wingsail technology and crew technique in the first season, and will greatly prepare them for the AC72.”

Global piracy costs billions, says study

Somalian Piracy Threat Map 2010 evolution from 2005 to 2010 (full resolution)

From BBCNews

Maritime piracy costs the global economy between $7bn (£4.4bn) and $12bn (£7.6bn) a year, a study says.

The report, compiled by US think-tank
One Earth Future (Oceans beyond Piracy), calculated the amount from the costs of ransom, security equipment and the impact on trade.
The majority of costs came from
piracy off Somalia, it says.

Although the costs are said to be difficult to assess, one researcher estimated they had increased roughly five-fold since 2005.
Despite an international effort to patrol waters, the number of reported incidents of piracy has risen over recent years, and the areas in which they operate has grown.

'Treating the symptoms'

The study, launched at the offices of UK think-tank
Chatham House, said there had been some 1,600 acts of piracy, causing the death of over 54 people, since 2006.

Looking at the problem in three regions - the Horn of Africa, Nigeria and the Gulf of Guinea, and the Malacca Straits - the report suggests that the biggest costs arise from re-routing ships to avoid risky areas, which is estimated at between $2.4bn and $3bn.
Meanwhile, about $2bn is spent on naval operations off the coast of Somalia each year.

"Some of these costs are increasing astronomically," said researcher Anna Bowden from the Colorado-based One Earth Future Foundation, which conducted research for the study.
"What is even more concerning is that all these are simply treating the symptoms. Almost nothing is being done to treat the root cause."

At the start of this year, around 500 seafarers from more than 18 countries were being held hostage by pirates around the world.
Somalia has been ravaged by internal conflict for two decades, and pirates have flourished amid the lawlessness.
