Velomobile Stitch and Glue

I am trying to make time to work on the seat. Haven't been able to get to my dad's house where the material is. I am guessing I might take a few times to get the seat profile down.

I am thinking about how to apply stitch and glue boat building techniques into velomobile building. For my first project I figure I want to make the body as inexpensive as possible, since I can always reuse the mechanical parts for another velomobile later. I have been thinking of simple but decent shapes for the shell.

I read that the angle on the rear end should be 12 degrees or less. The idea I have drawn up has a 13 degree angle. Pretend there is an imaginary line that extends along the edge of the velomobile and you measure at the point the rear begins to narrow. The angle from the imaginary line to the point the body curves to the rear should be less than 12 degrees, which makes for a long body if it has any width to it.

I drew two lines to represent the angle that is being measured for a visual. Like the old saying goes, a picture is worth a thousand words.

I decided to play with different roof lines to see what kind of effect it gave. A lower roof line in the front gave a pretty neat effect. Will need to verify measurement to see how low the top can comfortably be. I think my ideas are within being able to use the stitch and glue technique. My drawing has a width of 38 inches and a length of over 9 feet. I am hoping to make room for a back seat.
