Hi Bill,
I wasn't planning on building a upgraded Hunley, but I just think it is
interesting the way the ballast tanks do not exhaust to the out side but instead
compress the inside cabin air. They do not compress very much air and I
doubt you would need dive tables. Does anyone know of a sub that functions
like that? I guess there is no real advantage. The onlly advantage I
could see is maybe stealth, since there would be no bubbles as you
submerge. Once you are negitive or neutral bouyant then valves would be
closed and you would maintain 1 atm inside the sub.

Hi Brian.
I know it isn't you talking about making a
replica Hunley yourself, and that you are talking about the man who made the
replica.
If the man who made the static replica,
made an exact diving replica of the Hunley except for the improvement of
closing in the tops of the ballast tanks, you still have to contend with
decompression tables like an ambient sub would, depending on how
long
you operated the replica with the interior
pressurized. You would still have to turn the crankshaft by hand using
uncomfortable, sweaty passengers and to be historically correct only have one
candlelight of light. There is no doubt
it could be done. If you enclosed the
ballast tank tops, added electric lights, scrubbers, did away with the
crankshaft taking up space and added an electric motor and modern safety
features, even though it might look like the Hunley externally,
it would be totally different. Except for the
exterior looking like the Hunley with a weaker rivited as opposed to welded
hull, I think the time and effort would be better served building a newer
design. I just think for the time and effort it would take
you wouldn't get the depth and use out of it that
you could get out of a more modern design for the same money, time and effort.
I love the old civil war era and even earlier subs. But I like them as
historical museum pieces. But as always.......
to each their own. If the gentleman has a burning
desire to build it even though it might not be practical, who am I to fault
him? More power to him. Perhaps it might be nice for civil war reenactments,
but the public wouldn't be able to see or
appreciate it working underwater unless you had
divers videotaping it underwater, and if that is the only way the public could
see it underwater, why not just do a computer simulation instead? If he wants
to build it simply for the accomplishment of
building it, then fine I guess. But would it
really be worth it? I guess that depends on the state of mind of the
person building it.
Kindest Regards,
Bill Akins.

Hunley
You're right the way they made that open at the top of the
ballast tank is not good. If the boat ever became tipped over
the water in the ballast tanks could rush into the main part of the boat and
it could become unbalanced.
the Hunley had a very heavy keel
however and it would be unlikely that it could invert it self. They
had a safety system where they could unbolt the heavy keel so they could
surface.
I guess the big error was making it so water could
continue to pour in the boat if you forgot to close the inlet valve.
But say you sealed off those balllast tanks except you put a valve open to
the main human compartment of the sub. Then it would be exactly the
same as before except that you could shut that valve when the ballast tanks
became totally filled.
With that set up it would act just like
the Hunley, in that, when the submarine submerged you would not see any
bubbles because the air would be getting compressed in the main hull
area.
and when you pumped the water out of the ballast tanks, the air
inside the sub would uncompress.
