Summerwind: Kings Point's `New' Flagship

Wow!  Summerwind - after a $8 million refit - has been donated to the U.S. Merchant Marine Academy at King's Point.  I am very excited to learn that just across the Sound from City island Y.C. will be the home of this classic designed by John Alden and built by Morse Shipbuilding, Thomaston, Maine in 1929.  The story is HERE
Update: SummerWind sailed up the St. George River to visither builders at Lyman Morse in Thomaston.  I saw her as she entered the river from the Muscongus Bay and got a great photo-op.

Lobstering - tough times in Florida and Maine



NEW YORK (CNNMoney.com) -- Maine's lobstermen are working harder for less, as demand drops for their expanding harvest.
Lobstermen pulled in a robust 76.3 million pounds in 2009, according to the Maine Department of Marine Resources. That's the largest harvest in years, according to state records and estimates, but only in terms of volume.
The 2009 take was worth $223.7 million, which is about $22 million less than the prior year, according to the department. State statistics show that the harvest has dropped in value, year-to-year, since 2005, when it totaled nearly $318 million.
As with most things, the recession is to blame. Cash-strapped consumers are avoiding delicacies such as lobsters, driving down the overall price, according to George Lapointe, commissioner of the Maine Department of Marine Resources.
"I think it's largely a function of supply and demand, and the world economic condition," he said. "Lobster is a luxury product."

Ode to the Gowanus Canal



The Gowanus Canal just got named a Superfund site.  So I guess it will get cleaned up.  But not restored to marsh.  The Lowes parking lot is here to stay and the bulkheads.  But the Times issued a call for photos and paintings of the Gowanus.  And there is some beautiful stuff. HERE is the link

Issuma: northbound


Richard Hudson and Issuma are northbound.  East of the continental shelf about 26 degrees South , 42 West, nearing the Rio DeJaneiro parallel.  This is sunrise at sea this morning.  From the set of the headsail it looks like the wind has shifted to the north.  Follow the track and Richard's occasional commentary and photography HERE.

Tall Ship Concordia sinks with 64 aboard - all saved



AP February 19, 2010


A Nova Scotia-based ship carrying dozens of students has sunk off Brazil, but everyone is safe and there were no serious injuries, officials say. 

The Brazilian navy said the tall ship 

SV Concordia went down about 550 kilometres southeast of Rio de Janeiro in rough seas.
West Island College International, of Lunenburg, which runs the 
Class Afloat program, said all 64 people aboard were rescued from four life-rafts by merchant vessels early Friday.

The 48 students, eight teachers and eight crew had to abandon ship and spent the night in life-rafts equipped with blankets and some food. A Brazilian navy helicopter spotted the rafts and dropped medical supplies.
The rescued people were expected to be moved to a navy frigate and taken to Rio de Janeiro. 

Ships with poor stability get struck by microbursts and ships with good stability get struck by squalls.


For intelligent discussion of the stability issues see the Wooden Boat Forum


Richard Hudson on Issuma was approaching that region as he makes his way north from Uruguay in deep water east of the continental shelf.  he did not encounter the storm system.  But Richard  went through the weather forecasts he receives on board and provides this report(with some interpolations by me):


[Note that Beaufort scale 8 is 34 - 40 Knots with waves 13 - 20 feet.  And that these are informed guesstimates.  Actual conditions may have been more severe.  We won't know the analysis for a while. - GWC]



According to the AP story, it was Thursday night, so Feb 18, and the ship was about 550 km SE of Rio de Janeiro.  That puts it likely in Forecast Area Bravo (possibly Delta--my forecast area map is not very detailed).
