Moving your stern planes aft of the prop will enable you to vector the thrust and thus give you a bit more pitch authority; however, if the stern planes you show are moveable, king they should provide all the pitch control you need.
The trailing ends of the horizontal fins on the NAUTILUS MINISUB are hinged to act as stern planes ahead of the prop about where yours are, and mine work just fine. The boat crash-dives really well.
If you'd like to see it diving (and haven't seen it already) go to the FREE VIDEO CLIPS page at VulcaniaSubmarine.Com and click on the link for NAUTILUS PROVING TESTS; there's also a link on the TESTING THE NAUTILUS MINISUB page.
No AutoCad. I used MSpaint on my old 133Mhz computer. "Stone knives and bear skins" I know. But it is all I gots.
Yes. Both the fore and aft planes are intended to be moveable. The drawings just show the overall plan. Fine details will be worked out in 3D as I come to them. Wouldn't do to get a faulty mindset entrenched at the get-go. Because we all know "No plan survives contact with Reality."

Yep. Reminds me of building the NAUTILUS MINISUB. After the 2-1/2 years of design development, the next 2-1/2 years of metal fab work was combined with ongoing design and redesign while I figured out all the little details of how to do what needed doing.
Wake up (oftentimes in my coveralls on the floor) with my clipboard, and go over the work list with morning coffee. Then, all day and into the night in the backyard working with the torch, grinders, and welder. Then, inside for dinner over the clipboard and a night of design work while I made sure about the next day's work list. A lot of nights I fell asleep on the floor. It went like that for 2-1/2 years. What a bee itch!
Too many cuts and burns to count. Steel in one eye. Respiratory problems from welding inside the hull. Back strains from lifting heavy weights. Almost lost one of the family jewels when a cutoff wheel exploded. Nearly crushed more than once. Pneumonia from working in the rain. Heat exhaustion from welding inside the hull on hot days. Hearing loss from high speed grinder noise. Neighbors trying to force me to quit. NONE of that was part of the plan!
Ya gotta love it!

Yes. I have seen them. And I have that paper model - not assembled yet, but I have it.
That first site looks a lot like Greg Sharpe's design. So much so that I wonder that the site owner can sell it without Greg's permission. But since it is also very close to Verne's description I suppose it falls within the public domain.
