Very cool story. I wish you luck in finding it. Try running the CF's through DMV and see what comes up. If it is still in CA you may be able to track it down. Also if you have the original Hull ID you can try running those #'s. It may take some digging but it is possible. Quickjet found his parents original flattie some 20+ years after his Dad sold it and is currently restoring it. He may have some tips. Throwing it out in these circles could drum up conversation and lead you to the boat. Keep us all posted on your quest.
