Brian, after I replied to this email I decided to
upload ten pics to the Conceptuals section of my Kodak site. I've
"invited" the group to view them from the site itself.
Hope you like them. Bill Akins . . . you may
like these, too.
Warm regards,
Rick L

"Frankenboot"
What if you had a large surface vessel that had a
large volume of air, say just a simple cylinder, like 6' in dia by 20'
long. That would give you quite a bit of floatation. But if you
tried to go submerged with that you would be having to move a very large mass
underwater. But what if you opened the ends of the cylinder wide open
and ran propultion through that space, then that space would not really be a
displacment factor. The only dispacement would be just the rim
of the cylinder. Turning might create problems but you might be
able to get around that somehow.
This might be a way to cheat your displacement of
a large surface vessel with out paying the price for the large mass under
water. The devil would be in the details.
My 2 cents
Brian

Paul,
Yes, I found Dougs site some time ago, there's some pretty inspirational
stuff in there. It is all part of why I believe this to be possible.
And yes, the WWII boats have a shape that is much more practical for me
than my original idea and I don't need a double hull per see for the
ambient. Imagine a forward bow tank that could double as a vee berth! Large
volume, dual use, well baffled, waterproof roll up mats stowed for divening.
Fleet boat or U-boat, builders choice.
Is it doable? I don't know yet. I recently discovered the 444 cf hp
cylinder, kinda puts a little different spin on things. Long narrow shape
for a hull?, small compensated airspace for machinery?, four of those
444's?, money, time, effort...what precisely is possible?
Even though I had found it, thanks so much for the link Paul.
Joe

Boy I think I'd look at Doug Jackson's http://www.submarineboat.com
website first for comparisons. He's building a dry
ambient where
most of the SportSub's are wet ambient. Doug has a large
surface
cockpit/rear deck area which obviously floods when underwater
but which
provides a nice seating and cargo area while surfaced.
Doug's design looks different from most any other sub, and
different
from Joe's WWII look, but I think it has some great practical
ideas and
more similarities to what Joe is describing.
Paul
Rick,
This sub uses the main cabin as ballast tank http://www.ivccorp.com/
Here is proper use of the other suggestion http://pbskids.org/sesame/ernie/index.html
Thanks :)
Joe
