The windshield has a 3" camber, same as the cabin top
Measuring along the rake of the windshield 27" uniform across width
Tried to get the line of the coaming to flow into the side screens on a nice sweeping curve
Unfortunately impossible to get a true perspective of the scale I drew a scaled picture of Nina and scaled the windshield and cabin using my actual dimensions and it looks right (to me). I can stand at the helm and look under the top edge of the frame and see all the way to the horizon so am happy with that.
