I called him in the mid 80s, to ask about the boat.  His wife
answered the phone, and wanted to give me the sub!  At that
time, they told me, it was in storage, not having been in
the water for a "long time."  

He said he'd never drawn any plans for it.  He'd done the 
calculations as he needed to do them, and not kept much.
