How was Illusion designed?

With the free Carene 2008 software:

 The software is easy to use, here is a picture of early designs on a 9ft length. I decided that was too small for comfort, eventually designing her at 10ft.

You enter the length, half beam, rocker, panel heights and press the button. It's that simple.

The only real dimensions I had were that Elusion was 9ft long and 38in wide - all other dimensions were reverse engineered from photos found on the Internet.
