Hi Jim.
I remember the name of the sub owner selling C Bug now. Karl
Stanley.
Here's a link to his page from his site that shows and tells about C Bug
for sale.
You can find a few links by searching online of articles and more
pictures of C Bug in action.
C bug uses her decent and surfacing inertia to propell forward without
any motor or engine.
Karl may have installed a small electric motor recently but I am not
sure.
He is asking $50,000 dollars for it. This is a proven sub that has gone
down thousands of feet.
It is a two seater and I think looks very cool. Karl designed and built
it all himself. He has designed and
built another sub that he is using for tour in the islands and doesn't
use C bug that much anymore.
Before you consider spending $45,000 on the e bay dubious
baby nautilus, I would take a look at Karl's sub.
Kindest regards,
Bill Akins.

Hi Jim.
Don't spend $45,000 on that sub. That is WAY too
much for a sub without support hoops, any kind of practical propulsion system,
drilled thru viewports, uncertain welds, and most especially one that has
never dove.
I forget the name of it right now but there is a
PROVEN sub for sale for $50,000 that you could be certain of. . Other fellows
here might know of it. It is the two person gliding sub that a
gentleman
built that got somewhat famous for diving and
surfacing using its inertia from diving and surfacing to move forward. I think
it is called SEABUG. It has dove to thousands of feet. I saw she was for
sale since he built another one.
Although my personal hands on experience is
limited to wetsubs, I have learned a great deal from the fellows here and it
just sounds like too much money to me for that unproven propane tank hull
natilus.
If it was $1500.00 like the bid was the other
day, then maybe it might be worth buying and modifying, but $45,000? That
sounds excessive for an unproven boat.
I think you could get more value for your dollar
than that natilus sub. I would hate to see you get taken advantage of.
Kindest regards,
Bill Akins.

Hi everyone, and thanks for your replies so far. Very
helpful.
I've just learned that the Ebay sub has a modified propane tank for its
pressure hull. I believe there have been discussions about that very
subject here before. Is anyone willing to briefly outline the pros and
cons of using a propane tank as the basic pressure hull for a psub?
Also, I'm interested in your discussion of oval shaped pressure hulls,
especially since the tower on the Ebay sub is oval shaped, and sits on a
large oval shaped hole in the propane tank hull. Am I correct in
assuming that might decrease hull strength against presssure?
And can anyone tell me what a fair price of a Kittredge K-250 submarine
might be? I've learned the Ebay sub takes much of
it's design from the K-250. The owner says similar subs sell
for $100,000.00, and he is asking $45,000.00 for the Ebay sub. Does
that sound about right?
Thanks to everyone for the assistance. This is a great place to
get information about psubs.

I
can see what you mean about this ebay submarine. It
looks as if it was
built mainly for looks with no real
intentions of it diving. There
seems to be no kind of
internal bracing that a pressure hull should
have. If
you added all the additional bracing, drive
system,controls
and equipment needed to really dive
there wouldnt be any room left for
a pilot. The view
ports seem to be an after thought just cut out
and
bolted on. Who knows how well the welds were done? I
doubt that
it is even water tight on the surface.
