Where does your depth gauge show relative to your sub?
From the water line or from the keel?
Is your depth gauge already calculated for your draft?

Yikes. Go to the control room view in the game, read the depth gauge where it says "SALT WATER DEPTH TO KEEL", then hover the mouse pointer over the button that says "DEPTH UNDER KEEL".

Hey fellas, Sorry it took so long to reply.

Heres a good one for the Yellow sea:

Cool thing about the charts is how much you can zoom in. Ill have to do some testing to see how accurate the soundings are, as well as how they line up Long/Lat wise.


Update: some of the charts are not viewable online, need to be purchased. Many charts do work though

Even better:

Its an interactive bathymetric map. Happy hunting :Kaleun_Salute:

Honestly I just noticed this. I don't typically do the stroll around the sub other than being on the bridge so I never noticed the depth under keel on the meter. And I guess constantly looking at the 3 big round dials always kept me from looking down and the smaller number below. Now that I know they're there I don't have to keep switching back and forth on the dials.
Thanks for pointing that out.
Although I think if I'm within 16-17 feet of the bottom I'm already in trouble...LOL.

Try going into the control room view while on the surface and look at the big depth gauges (the fine scale ones that go to 165 feet) and you'll see the depth varies around 15-17 feet, sometimes to 20-22 if the weather is rough. Just took a look at a pic of a real one, minimum number is 15 feet. Check the game; yep, same.

The sub captains had crap for charts, often using 20 year old National Geographic map inserts to figure out where they were. Soundings? Forget it! What we have in the game is magnitudes better than what they were stuck with.
