When talking in a lock no one says to the left or right. They say port or starboard. But most of the time they say how far above or below the long wall and how wide in feet
195' by 35 ' for rake barges and 200' by 35 ' wide for box end barges. The largest tow I know of was pushed by the MV Miss Kae D(ACBL) back in 1978 when she took 72 barges past Memphis.Bet that was a lot of fun to check for water and tighten rigging every watch.
I did ,too.Too many pilots got together and bought me my first walkie talkie because they couldn't tell how many fingers I was holding up when I signalled them.
Those are not Detroit brand engines ,,those are known as EMDs built by GM , maybe in the city Detroit ,,very reliable engines hands down,I'm not sure but I think there more than 4000 horse power also
EMDs are not Detroit Diesels. also you may want to run a calculator over the number of hours claimed in a 'towing season', there's only 8760 Hrs in a year.
lol if I heard a deckhand talk like he did 'making a lock' I would walk over and smack the radio outta his hand and take over, comon ppl reserch a little!! left and right does not exist on any professional workboat....port and starboard!!
