Glass Boat Windows

There is not a single square nor rectangular window anywhere on the lunar lander dwelling (built like a boat) that I’m building. And the building department has forbidden any acrylic boat windows. And all windows must be double pane at least, with argon between the panes. Windows from stores like Home Depot are all rectangles. What do I do?

At Pacific Marine Expo fishing industry boat show last week I found several companies that build double pane glass windows to any shape. I simpy take them an autocad file of the shapes I want and they cut them out.  This could apply to any multi needing actual glass windows.

I do not know about price yet. These companies are:

Thorodon Bushings/Unstayed Masts

I met with the Thordon bushings guys at Fish Expo. They normally do plastic tugboat rudder shaft and prop bushings. Off the shelf mass produced products are a fine way to keep costs down. They told me that they sell bushings up to 8 feet in diameter. In their experience a polymer on polymer bushing situation is to be avoided. This is however the definition of a Tides spherical bearing.  They look ideal for unstayed rotating mast bearings.  I have been specifying them for rudder bearings on my boats for years now.
