The SS Lea A Tregurtha

[BrushWolf]

Today, well yesterday was Veterans Day and while we usually think of the people that have served there is a ship that sails the Great Lakes that earned two battle stars as an S type tanker in WWII the Lee A Tregurtha which started life as the USS Chiwawa a S type tanker of 501 feet launched in 1942. After the war she was acquired by Cleveland Cliffs, lengthened to 730 feet and widened to 75 feet. In 1966 she received a bow thruster. In 1976 she was lengthened to 826 feet and in 1978 was converted into a self unloader and in 1982 she got a stern thruster. In 2006 she had her steam plant replaced by a 8040 HP diesel and in 2016 she had exhaust gas scrubbers installed. She is ready for another 80 years of service.

Not sailing in fresh salt water has a tendency to  prolong the life of a steel ship.  As for new ships, the first Great Lakes steamer delivered last year was the first new steamer built in almost 40 years...

Not sailing in salt water has a tendency to prolong the life of a steel ship.  Salt water allows ion transfer at a faster rate than fresh water.

Doh - THAT"s what I meant!!!!  FW extends the life a steel hull!!  AS for wood hulls, switching between FW and SW helps get rid of the wood eating worms that are in tropical waters...
