It’s a beautiful craft.
For those who equate batteries with Satan, I was watching a WWII documentary on submarines. They couldn’t function without batteries. They could have used smaller, greener ones at the time.
My German great grandfather was an entrepreneur in Danzig, Germany. He owned several battery factories around 1890. All was lost when the Russians and communism came in 1945. I’ve often wondered if the batteries were used in German WW I and/or WW II submarines.
