Hey, on very cold days it seems like it takes eight hours to start my car! LOL! I may have met you in Baltimore inner harbor that day. I must say, I am very impressed by that ship, and I also admire all the love and devotion you guys (and gals) have the John W. There are very few people these days that have that much desire to preserve our history.
My guess is that since these engines cant be turned off like in a car, they have to gradually slow the main engine down while engaging the reversing engine simultaneously.I did the tour of the ship the other day and I can only paraphrase what one of the engineers told me.
I have worked on this ship for about 6 years now. In this video they are only testing the pistons and engine to make sure everything is working properly. And also, the engine is not at all like turning a car on, unless the car takes about 8 1/2 hours to turn on!
Yes I know that but look. The reversing gear is constantly shifting between ahead and astern. The piston and main rod crank aren't doing any revolutions but merely moving a bit in one direction, then one bit the next.

My guess is to keep the engines warmed up with out making any headway.

They're shifting between ahead and astern, why is that?

ahead....going forward, direction bow(front) faces.
astern......reverse, direction back end of ship.
