[PSUBS-MAILIST] Actual Inclinometer Usage Need?

[MerlinSub@t-online.de via Personal_Submersibles]

Steve on the Euronaut we have multiple of them on all axis.
 
One is longitudinal bubble and shows very fine + - 5 °.with less than a 
half degree.
We use it during diving to get the boat on a propper even keel periskop 
depth - before we dive deeper.
Otherwise we lost energy moving forward.
This is in use on each dive and also to trim the boat stern heavy on the 
surface..
Also helpful during refueling the submarine with fuel.
 
Another one is a weight typ from a russian submarine and in longtidudinal 
direction and rough + - 45 °
Only useful during crash dives in front of enemy aircrafts.
(Over 45° we use the handheld Microfonspeaker on a spiral cable of the UHF 
radio.)
 
One is from a sailboat +-15° and to show trim over the beam - and not very 
needed.
 
Two are from the buble globe typ (flat horizontal discs with the bubble in 
the center and showing in all horizontal direction the trim.
One of them is in the diver chamber and in use if we want to move the 750 
Kg Anchor weight out and in - and very needed.
The anchor weight nloks and goes heavy if the boat is not in all direction 
horicontal. Both have +-5° all over the horizont.
 
On a small sub I would recommend only one : A +-5°  longitudinal simple 
bubble typ.
If you are for example 2 degree stern heavy you may will not notice it.
If you drive short over the ground your stern maybe make a lot of mud 
clouds.

So how often are small subs needing to know inclination in real life 
operating experiences? I have bubble inclinometers but am debating if I 
really need them in a 1 person K-250.  I think the pilot is capable by 
observatory sensation to have enough awareness of inclination without an 
instrument. 
Thoughts?
