Re: [PSUBS-MAILIST] Sensor Interfacing

Hi Matthew,  My sub "Esmae" which I am currently re-designing does sit in a upright position in it's "flipped" orientation (see moki exchange).  But moving through the water like that would require a streamlined shape around you.  Take a look at one of  John Holland's first subs where he was essentially standing with his head sticking up at the top looking out, he controlled the dive planes with a lever.
