For the curious:

I was interested in learning more about the pedal powered Hobie Mirage Drive, so I requested some info from the company. It turns out they have a patent on it, so if you want to check it out and don't have access to a local Hobie dealer, you can go to:

http://www.uspto.gov/patft/index

The patent number is 6,022,249

If you can view TIFF images, you will be able to see the full page drawings. I'm not sure why they don't use acrobat...if you are having problems viewing the TIFF files with Internet explorer, there is a plugin that will work, you can find it at:
