Just what are you trying to say...? :hmm:

Yes, the depth gauge is in meters :shifty:

[THE_MASK]

Correct me if i am wrong . In SH3 the depth is the depth you are at from the surface . In the picture it is the depth under your keel .

[Tigrone]

It's measured in how far your keel is below the surface. There is so much topside variation from boat to boat that there is really no universal fixed point to use there. The keel is an absolute reference point.

Depth is measured from the keel down in the same way--depth below keel.

Almost forgot, that is one of 2 depth gauges. There is a second showing depths in a broader scale to 450' or 600' depending on the class of boat.

OK , thanks.

You mean you've seen shots of dials with imperial measurement? Where?

[NefariousKoel]

I'll be very sad if depth isn't measured with the Imperial system. :o

[Drokkon]

I also will be saddened if it's not in imperial also. It'll remind me too much of the controls of a U-boat or a russian alpha sub.

[flintlock]

I'd be surprised if it's metric. With the attention to detail the devs have shown in the past, I would imagine they would desire to keep this historically accurate. I have faith, blind or otherwise, that it will be in the historically correct US imperial system.

Yes yes -- I see the glass as half full. ;)

[DaMaGe007]

I think it will have both, like most flight sims you can choose whichever.
Its a simple mathmatical conversion and a different dial.
I would be very surprised if Im wrong.

Yes, all the screenies show the depths in feet. 165' foot shallow depth dial and either 450' or 600' deep depth gauge depending on class.

[Boris]

Strange, first it looked to me as if the left dial shows feet, and the right shows meters... but this can't be, both dials are pointing to the same value.

I'm sure they made these dial authentic. The only thing that says meters is the numeric value at the bottim right of the dial.

But if the dial shown in the first screen is obviously meant to be the detailed dial, then the increments are too many to be meters.

Looking at it this way, I doubt the devs have even included a meters option, as this would necessitate different dial textures.

As I said in another thread: In one video (the GIGA one) you see a Gato at PD and the gauge is showing the number '60', so the gauges are showing feet.

graphics are looking nice

[Captain Krunch]

Here's a photo I took of the USS Lionfish's diving station. As you can see, the real thing goes to 165, just like the image that 08x15 showed above.

In addition, the Devs said this in reply to a question on the Daily Dev Answer thread at the Ubi forum:

Q: Taifu_Noodle: What units of measurement will SH4 use?
A: Silent Hunter 3 used the same measurements system as the Kriegsmarine - based on the metric system. For Wolves of the Pacific, we will of course use the imperial system since this is the historical solution. However, we are considering to have the game switch to metric as an option.

So I don't think we have anything to worry about.

It looks to me to be just like SHIII, but in feet. 165 is the shallow depth guage, 600 is the full depth guage. 165 feet is not quite 51 meters.

I think your right steve

The shallow water depth gage is used for when the boat is operating above 150 feet. The deep water gage is used when operating below 150 feet. Both gages are in feet and not meters. Shallow gage is for more accurate depth control. All depth measurements are made from the keel, so when you go to periscope depth (58 to 62 feet) that depth is from the keel, so the top of the shears are only about 10ish feet beneath the surface. While sitting on the surface, the depth gage should read around 18 feet.

Depth below the keel is not a gage, but a sounding indication from the fathometer.

Good explaination! One extra comment - I remember reading somewhere - and have attempted to find out where - that the US subs were the only boats that registered the depth that they were at, as from the surface to the keel.

A U-boat at 12 meters is at periscope depth, which is almost 40 feet. That means depth to keel. A Fleet boat is much larger (about twice in dimension and 3 times in displacement), so her depth to keel at periscope depth is about 60 feet. In both cases the top of the shears would only be submerged about 2 to 3 meters, almost close enough to disturb a still surface.

Not to belabor the issue but I found a British web site that covers their submarine service. I received an answer to a question I sent them, about depth.

The answer came from a Chief Stoker who entered the British Submarine service in 1952 where they were still using WWII standards. Their periscope depth was 32 ft. and the depth was measured from the surface to the middle of the hull. Later they went to Nato standards - that was like most Western Navies, and now measure from keel depth.
