This is, essentially, a tank that can float on water, no? One more video inside.
Interesting! I just learned from Gizmodo that there’s a giant floating prison in NYC called the Vernon C. Bain Correctional Center. It’s located at 1 Halleck Street in the Bronx, directly across the water from Riker’s Island. Vernon C. Bain Correctional Center is a 625-foot long by 125-foot wide flatbed barge with 100 cells.
This is cool and all, but if he was dreaming big, why didn’t he dream up a longer boat?
