This is the top deck of the ship. The floor planks are actually been constructed one by one, using a
flattened & resized cubes.
The 'side fences' (i don't know what it's really called ..), are mainly cylinders, arranged vertically & horizontally
for the look. In this scene, I haven't added the wooden handle which sits on top of the fence, which took me a lot of time to arrange
it to look straight.
As for the window pane & frame, it's all Boolean using cubes & cylinders. Figure it out yourself.
The big exhaust 'pipe' is a cylinder ... the rest are also Boolean results ...
