Apparently my smiley didn't have the intended effect. I received, what I
consider to be, a semi-nasty direct email and now this posting.
It is because I respect for the knowledge contained by those here that I
ask
such questions. I'm not demanding respect since I've read through several
chapters of a handbook. Respect given to a person is attained by what EF
Hutton used to say on their commercials, by earning it.
I know that I'm a newbie. I know that there are many things that I don't
know. I am very humble in regards to my sub (and many other fields as well)
knowledge. But as far as I can tell this is the best place to ask specific
questions to ones who have that knowledge. In fact the About Us page on
psubs.org says "PSUBS.ORG was organized to promote and encourage the
discussion, designing, building, certifiying, owning and use of personal
submersibles".
I hope that I can garner some respect for my desire to learn and to safely
and properly build a psub. Perhaps over the years I will be able to gain
some respect as a submariner.
Back to my original post:
How do you deballast? & Do you have two independent means of doing this?
By seeing how others are doing this, I learn. If someone successfully is
using a similar method to my design, then that's some confirmation of my
design and progress. Obviously my design would still need to be tested. If
someone uses a method that I couldn't conceive of, I learn about that and
see if it would work better.
I hope I have clarified myself and explained my method of madness!

Marten, I'm sorry to say that respect don't come by reading a book...
But you still have my respect anyway!
