On my last boat, I had a pilothouse with a seat. I found that I never sat down. I was always standing, leaning back against the seat - never sitting.
I didn't want to waste a lot a precious space with a seat here. Instead, I wanted something really comfortable to lean back on.
I started with a lot of cardboard cutouts and arrived at a design idea.
This is the "jig" I used to laminate the back.
