...and once I was coming in from offshore in an old A model with Capt [redacted] and he turned off both the generators and the battery and the old girl still hummed along nicely without the slightest disturbance what-so-ever. If I remember, with one HP out you had to slow down, but with 2 out you could still maintain warp speed to ensure you weren't the 2nd last ship home and thus avoid warming a seat in the crew room until the last ship crossed the coast.
