Rough seas for tough mariners


Deadliest catch : respect to these guys working in terrific conditions

From AssociatedContent

Previous week (on Friday),
Reuters reports that U.S. Coast Guard cutters and helicopters rushed to assist a disabled freighter adrift in the Bering Sea with 20 crew members aboard and carrying a cargo of oilseeds and fuel.

The 738-foot, Liberian-flagged vessel
Golden Seas, owned by Paragon Shipping Inc of Greece, alerted the Coast Guard before dawn of a main engine failure in rough seas about 70 miles north of Adak in the Aleutian Islands chain, Coast Guard officials said.

Two Coast Guard cutters and two MH-60 Jayhawk helicopter rescue teams were dispatched to aid the crippled vessel, which was drifting to the southeast at roughly 2 miles per hour.

No accidents, spills or injuries were reported, said Coast Guard Petty Officer Jon-Paul Rios.
But weather was bad with gale-force winds and 28-foot seas, he said.

The ship was loaded in Vancouver, British Columbia, before embarking on a voyage for the Middle East, said Darrell Wilson, a spokesman for the vessel's management company, All Seas Marine.
The freighter apparently was traveling a busy shipping corridor known as the Great Circle Route, which extends from the West Coast of North America through the Aleutian Islands to Alaska and on to Asia.

"They had some type of engine problem. They have not lost all power," Wilson said. "They have limited power, but it's just not enough out there in these weather conditions."
The route is known to be treacherous due to stormy weather, icy seas and high winds.

Remember the
Deadliest Catch serie from Discovery Network.
Deadliest Catch is a documentary/reality television series produced for the Discovery Channel since 2005.

It portrays the real life events aboard fishing vessels in the Bering Sea during the
Alaskan king crab and C. opilio crab fishing seasons.

The Aleutian Islands port of
Dutch Harbor (located in Unalaska, Alaska - see Marine GeoGarage-) is the base of operations for the fishing fleet.
The port of
Unalaska/Dutch Harbor is the main port and field base for the storied Bering Sea king crab fishery.
Dutch Harbor has also been the largest fisheries port in the United States, in terms of volume of seafood caught, for nearly every year since 1981.
Until 2000, it also ranked first in terms of the dollar value of its catch; since 2000, however, the port of
New Bedford, Massachusetts, has outranked Dutch Harbor in that category

The show's name derives from the inherent high risk of injury or death associated with the work.
The Deadliest Catch on the Discovery Channel is about life and death, fighting the elements, the bonds that are formed among men that put their lives in danger while trying to make a living.

The show itself centers around four main commercial fishing vessels; the
Cornelia Marie, Wizard, Northwestern, Time Bandit and the crews that man them.
On occasion the show will have other vessels as well.

Alaskan crab fishing is one of the most dangerous jobs in the world, so dangerous that the U.S. Coast Guard is on stand by when the commercial boats are out.
The vessels brave the icy waters of the Bering Sea in search of King Crab in October and the C.Opilio Crab in January.
An average of one fisherman loses their life each week during the season with 80% of the deaths due to drowning or hypothermia.

Here are some reasons to watch this show:
  1. Adventure is the number one reason to watch 'The Deadliest Catch'. The icy cold waters of January or the gale wind enforced waters in October are both considered hazardous season's. Either way they bring danger and adventure to the person watching at home.
  2. Appreciation of the price of C.Opilio Crab and King Crab. Every season lives are lost bringing in the catch. Think about it the next time someone complains about the price of Alaskan crab.
  3. Many of the crew members are related and the ones that are not still have a powerful bond. Being physical relatives and spiritual brother's gives strong ties to the crew members. Out in the Bering Sea it is just them against the sea and the elements.
  4. Danger is all around the cast and crew of 'The Deadliest Catch'. Anything can happen from a ship sinking as in Season 1 when the Big Valley sank losing 5 of its 6 member crew, to someone getting knock overboard with the heavy crab traps.
  5. Competition from ship to ship is another good reason as it would seem fishermen are always competing to see who is best.
Watch the 'The Deadliest Catch' on the Discovery Channel.

Open Boat Orchestra, music created by sailing


OBO (Open Boat Orchestra) Generation 1 playing a file from the Artemis IMOCA 60 during the Sevenstar Round Britain Race July 2010.
The venue on this occasion was Richard's Tinley's work bench at Tinley Marine Electronics in Lymington.
Shot by film-maker Richard Gooderick with sound recorded by Mark Ty-Wharton.

From Lia Ditton website

What if a state-of-the-art race boat could be transformed into a live, digital orchestra?
What sounds would be created from the force of wind and water on its sail and keel, and by even the smallest of adjustments of its skipper?
How would this music change over the course of an oceanic race?
And what if this soundtrack could be heard and mixed live by audiences around the globe?
These questions form the basis for Open Boat Orchestra or
OBO, the latest project from 30 year-old British artist and professional sailor Lia Ditton: using real-time data from a sail boat to create a unique experience in sound.

The idea originated in 2003 while Lia Ditton was watching the America’s Cup live on TV:
‘When the boat tacked, the bow moved through the wind so quickly and with such precision that the jib went flunk. The second sound was grrrhhhr. The main wasn’t being trimmed. It was trimmed: one single action, one sound bite!’ She recalls. Inspired by this and other sounds coming from the boat, the idea has since evolved into a full-blown project: translating one of the world’s most dynamic ocean races into the universal language of music.

Open Boat Orchestra (OBO) will play out on the international stage of the
Transat Jacques Vabre race which begins in November 2011.
The experimental edge to OBO lies in the unpredictability of how the boat will ‘play.’
In this respect, every stage of the race will become as much a work of music as an adventure under sail, subject to the forces of nature.

“We can’t entirely predict what the angle of the wind versus the speed of a boat through the water as it crashes off a wave will sound like; how one variable could audibly relate to a sequence of others. There could be periods of time, for example, especially in a rough North Atlantic where the music is loud and vivacious, while in the relative calm of the South Atlantic the music is wonderfully andante! What excites me as a sailor is that we might be able to optimize a boat’s performance beyond what it is possible to see and feel, by listening into the music as it is being created.”

How it works ?

Neither the sails nor anything else onboard will make an actual sound.
The sounds will instead be created digitally, using data streamed in real-time from the marine electronic instruments (
NMEA0183 output).
However, the data generated by the boat, also does not produce sine waves or audible sound.
The data streams are what control an ensemble of pre-selected instrumental sounds.
The boat moving through the water is thus the
synthesizer.

Defining exactly how many data elements are preferred to work with, what kind of function they should perform and then building the mechanics of how the data will control sound, patterns, tempo, key, etc. is the challenge.

The note, pitch and sound range of each source of monitored data will also be assigned, so that when all the different elements of the data stream ‘play’ together, they sound harmonic.
Each ‘instrument’ could be paired with a speed variable – boatspeed, SOG, or windspeed to determine volume, for example.

The music of OBO will be a blend of World influences.
As the boat races non-stop around the world, the sounds assigned to the load cell instruments will change according to a GPS trigger.
Down the Atlantic past Brazil, for example, OBO music will draw in the sounds of instruments native to Brazil; when the boat sails into the longitude of Africa, African instrumental sounds and rhythms will be brought into the orchestra.

What are we expecting to see as OBO completes its voyage?
We anticipate stronger winds and rougher seas to generate more extreme data readings and therefore more dynamic music, while in calmer seas the audio should be calmer and much softer.

Will fine-tuning the boat according to its music, also optimize the boat’s sailing performance?

“What excites me as a sailor, is that we might be able to optimize the boat’s racing performance beyond what it is possible to see and feel, by listening into the music as it is being created. We should be able to hear if there is too much backstay or head-stay tension, for example and so be able to trim the boat accordingly.” Lia Ditton.
