RE: [PSUBS-MAILIST] How to trim and ballast bigger boats.

[Hugo Marrero <HMarrero@hboi.edu>]

That is correct Carsten,

The setting of this buoyancy is a fine line indeed. That is where experience
trains you to fine tune your ballast so that you can focus your attention on
your dive. On bigger subs, of course, there is much more momentum and more
horsepower, but the concept is the same. And it is indeed also a safe
practice. This is one good reason for VBT's.

I did the same trick with the thruster of -Sgt.Peppers- but I learned
that you have anyway to  mach the right weight up to some 1-2 kilogramms
on this little sub - or the Thruster have to run all the time. Hopefully
the indication system on two VBT on Euronaut will be such fine that I
get very fine figures what is in. Unfortunatlly I didnt find up today a
cheap and fine seawaterresistant sensor which is pressuretight up to 50
bars for the 1,7 m ( 5,6 feet) high tanks. Any idears ?

best regards, Carsten
