Hi Joe and Myles.
Here are some links to Kent Markham's silent runner
II ambient half dry sub.
I bought my minnkota from Kent and along with the
motor he sent me a set of plans for both his
silent runner 2 and his delta wing ambient
subs.Both plans available at psubs too.
You can see the lower side door on the photos where
the diver gets in and out.
So you can see how the air bubble in the canopy
could keep from getting
flooded but the operator could still exit the sub
if he could not surface for some
reason, then come back to retrieve the sub without
the interior getting wet.
In the silent runner 2 it would not matter if the
interior got wet, but I am just
showing you this to explain the principle of how
the interior could stay dry in
the ambient designs you both are contemplating and
you still could bail without
flooding the interior. Think of an upside down
glass being pushed underwater.
As you go deeper the water wants to rise higher in
the glass but you keep it from
rising by putting more air pressure into the glass.
Then if you need to bail you can
swim out the bottom of the glass without having to
flood the glass itself. That way
you would not flood your engine or motors or
anything else in the interior you did not
want to get wet. Just no sense in flooding the
ambient. Just make sure you design an
exit hole in the bottom when you build it and swim
out your gopher hole if necessary.
Bill.
