The space under the skylight is only about 1/2″ to the deck. I had originally thought to print an overhead view of a Engine Room but there is a real lack of any such image online. I then thought of 3d printing something that would give an impression of the top of the engine etc. That means I need to remove the skylight framing to have access to the area under the skylight. If I cut away some of the hull under the skylight I can probably get at least an inch of space. Here .. I have highlighted said framing in green.
I can also take time to make the skylight “Mo betta” by making it a separate piece to be added to the Engine Room superstructure after that is finished.
