If you make your way out of the Gallery, You'll come out to the Main Deck. The deck itself is an old fashioned wooden surface, splinters and all. Overall it is well-worn and in need of some repairs here and there but still good.

When docked the Mamluki Harami sits out in open air, the way a deck is meant to be. But when in space there is a clear--but durable barrier protecting the oxygen and pressure. So the deck can be enjoyed and used without being sucked into space.
