Often HP steam was bled to the LP cylinders to start big marine steam
engines? Do you do you do that on your tug?

Steam was admitted directly to the condenser via a "snifter valve" in
order to raise vacuum enough to allow smooth starting, never heard of
admitting drum pressure steam to the LP, it would sure jerk the poor
engine around.

My tug has a very large for its power and quite elderly diesel. I only
operate other people's steamboats for a living.
