Frank,
What about a design where your sub surfaces underneath the mother
ship. I've been toying with the idea where my mother ship is a large
Carsten type sub except it would not have very deep diving capability, in fact
maybe no diving capability at all. It would travel like a
partially submerged sub, kind of like those drug subs (but without the drugs)
-just beer. Anyway my concept, which I will try to lay out on paper, would
be to have a permanent air space where there would be enough room so that
you could open your hatch. Rather than have a lock out chamber,
which could lead to sinking your mother ship, just make it so that you have
to swim out of the bottom air chamber to get to the mothership upper
hatch. It would only be a short swim and you could have ladder rungs to
hold on to. Once you get your sub up into the air space you could give it
a little extra positive bouyancy so that is doesn't have a tendancy to bob
around in there and cause some damage. Then once you're out of your
sub you could also secure the small sub with cables or straps or
whatever.
Just thinking ahead !
