Current lego sets are often covered in tile pieces to hide all the studs, maybe out of shame of being lego, which bloats the piece counts and prices even further, and makes it a pain to pose minifigs in them. Pic related is the interior of the sail barge, what should probably just be a flat plate is tiled over.
You'd be better off doing your own airship from scratch or using the 3 in 1 pirate ship if you MUST use a currently available set
