Brian,
Yes, the over hanging tanks fore and aft on a Kittredge sub
are soft ballast tanks. They are open bottom fiberglass shells and only
have valves for venting air in and out.
On a K-250 the hard tank is inside the sub and doubles as a
seat support. It has valves for venting air, pressurizing air, and a water
in/out valve.
On a K-350 the hard tank in located under the hull between the
two battery pods but plumbed similar. It's far more roomy in a K-350 with the
tank outside the hull.

Questions
Hi,
I have a question on the
ballast set up on the Kittridge subs, Is that over hang on either side
of the sub a soft ballast area? and then is there a hard ballast
(variable ballast) directly underneath the sub? Just from looking at the
pictures that's what I'm getting .
Also, if anyone knows, Looking at Carsten's Euronaute I can't
figure out where his ballast tanks are? The sub does not appear to have
a double hull so I'm starting to get confused ! Is the ballast
inside the pressure hull so that the sub is more streamlined? And so
with no double hull the sub is not intended to have any real
freeboard? Please if anyone could straighten me out on this it
would be greatly appreciated.
Thanks
Brian
