Live Global Ship Positioning

I couldn’t think of a better title. It’s a tongue-twister but it is in reference to the Live Ships Map on MarineTraffic.com based on Automatic Identification System (AIS) transponder data and iAIS.

You can find out a lot of information about ships underway. There is no data off the coast of East Africa, let alone Somalia, unfortunately. So here’s the Bay Area, as an example instead:

Clicking on one of the ships brings up its dox.

A micro view shows proximity of the boats and, in this example, you can even watch the pilot boat come out to greet the Filipino “Sun Right” ship and take over navigation for the Bay.

A macro view tells a very different story. If you pull out far enough on the maps you get green boxes with numbers indicating the number of data feeds. California ports show hundreds at the most. Green boxes around the Asian ports show numbers in the thousands.

Take a look at Shanghai. Pink squares represent navigation aids. Green is cargo, red is a tanker, grey are “unspecified”.

You also can create watch lists or “fleets,” search for specific vessels and ports, display their tracks, show predicted courses, and add GRIB (wind) data. Even small vessels should be able to easily incorporate this data into warning, distress and chart systems, marking a huge difference in situational awareness especially in low/no visibility conditions.

I am curious about the ability to build fleets or watch lists based on manifests such as port of call or country…imagine building a map with the tracks and the predicted courses for all the fuel tankers from or headed to a country.

I also wonder about correlating the movement of tankers to the rise and fall of fuel prices. It is said that diesel prices in the Bay Area rise when tankers arrive from Latin America and fill up. Not all the data is clean, however. I ran through the Shanghai ships reporting themselves as passenger vessels and found at least one that was actually a oil/chemical tanker.

SL33 Catamaran

Morrelli & Melvin’s new catamaran is a beautiful example of modern efficiency in sailing technology and design. The crew tells me that with just 17 knots of breeze on an easy-going day they were easily topping 24 knots of speed. During the Three Bridge Fiasco race in 8 knots of breeze the boat was sailing at 12 knots. They finished in second place and just 48 seconds behind last year’s winning time.

This will be a serious competitor to the eXtreme 40 design and may lead to the sort of transition of an entire fleet that we saw with the Melges 32 from the Farr 40.

One of the key differentiations between the two catamaran designs is that the X40 uses stiff hulls to offset the risk from huge loads on its lightweight frame. The SL33 design uses construction emphasizing strength in the skeleton; it adds weight in the beams, but has light hulls. Another major difference is that the SL33 was designed to easily come apart and fit in a 40 foot shipping container. It basically looks to be a more fun, less expensive and more convenient alternative to the popular X40s.

The design also is huge news in terms of the upcoming America’s Cup in San Francisco. While the premiere match races will be on Morrelli & Melvin designed catamarans (AC45 and AC72) the SL33 gives club racers and sponsors an option to invest in a similar design at a far more affordable and shippable format. That makes it not only a competitor to the X40 class but potentially a conversion machine to pull even die-hards of the mono hulls into the future of sailing, or at the very least force mono hull designs to adapt and improve.

See you on the Bay!

Updated to add Emirates Team NZ – TV News clips on the SL33 and the computers used to design them:

Vado a bordo, cazzo!

Audio has been released of the Commander of the Livorno Port Authority yelling orders at the Captain of the Costa Concordia (nearly 115K tons and 1,000 feet long) after it rammed into rocks at 15 knots in calm waters on the 13th, began to sink and was declared abandoned.

Here’s a YouTube version with translation. Note the line at 2:10 “Vado a bordo, cazzo!” (Go on board, cazzo!):

Italian maritime criminal law says a captain who abandons ship in danger can be punished with prison.

The captain of the luxury liner shipwrecked off Italy on Friday has explained his early escape from the vessel by claiming he stumbled into a life raft and was unable to get out.

Diving Under Antarctic Ice

I get chills just looking at the series of photos from a National Science Foundation photography mission and thinking about the survival gear necessary for a human.

The National Science Foundation Office of Polar Programs sponsored an underwater photography team to dive out of the US Antarctic Program’s base at McMurdo Station, on Ross Island in Antarctica. For three visits in late austral spring, photos were taken on scuba dives and field excursions at locations around McMurdo Sound: Ross Island and the Antarctic mainland. The team was led by Norbert Wu, a professional underwater photographer/cinematographer.

Here is a very small crop from my favorite photo of the entire series. You can probably guess why.

The Norbert Wu collection says it holds more than 6,000 research images and he has been awarded the “Antarctica Service Medal of the United States of America ‘for his contributions to exploration and science in the U.S. Antarctic Program.'”
