I believe that if you do some research, you will find that the Andrea Gail was
powered by a single John Deere diesel engine. It also was equipped with a
gasoline powered ice maker which had been problematic on previous trips.

One sentence, just one sentence, but it clearly shows the Andrea Gail had a
gasoline engine. At least in the First Edition (for those out there who know
what a First Edition is, the rest of you can go fry an egg).
