Trim weight

Puster Bill · 02-02-07, 04:14 PM

That is why just about every submarine had to do daily trim dives: To make sure that they had all the numbers right. Invariably, something would have been done wrong, or not accounted for. Just too many variables, at least in pre-computer days. So, every day the boat would be submerged (slowly!) so that the LI could 'balance' the boat.

I wouldn't mind having to do trim dives modeled to the extent if you don't you might run into trouble the next time you dive. This could be cumulative. Maybe you don't do a trim dive for three weeks. God, imagine the trouble you could get into you when your watch officer sees a plane and screams, "Alarrrmmm!"

Who would have thought that a sack of potatoes could ruin a whole day if not compensated for?

What if Bernard was on the toilet, releasing the last 14 (!) days of crap into the ocean? Wouldnt the boat pop to the surface like a cork? Or was toilet-patrols only allowed when surfaced?

Trimming the boat was an art that took a long time to master

You're not kidding especially when you're talking about those kinds of tolerances (only a hundred pounds!) compared to the entire weight of the boat itself! Wow.

No doubt about it, it's a tightrope of sorts...

A quick calculation shows that a hundred pounds of potatoes is 0.05 tons. Seemingly nonexistent compared to the 865 tons of a submerged VIIC! That's only a difference of 0.0058% between stabilization and falling to crush depth.

Again....wow!

The ever so famous "Prüfungstauchen" is pure mojo!:hmm:
