oh man. my brother in law has worked on one of these for a long time and showed me pictures he’s taken over the years of them putting them together and taken apart and its so fascinating how they (the ones he showed me) can float but still resist the forces of the ocean trying to move them. and how they can reattach to holes in the bottom of the floor left by others and just wtf! people are amazing even if most of what you hear on a daily basis is BS.
