OK so this Sky Deck is just too cool and I've been looking through videos. The doorway is much more weather tight than I imagined, just like any commercial building rooftop access hatch, and some have sinks and water up there, coolers, and all the general features you might find on a houseboat. The awkward part is the rooftop ACs that protrude into your deck and put off heat and noise while they are operating, and not sure they are getting the total air circulation they might need as I saw the forward AC partially buried up in the front cowling. A basement style AC may have been a better match.
