[REL] Surface draft and dive time mod + more (beta)

[AVGWarhawk]

You should try the S class. I think I can make England on one tank . Well, maybe not but fuel consumption is good if you use ahead standard.

linerkiller, will run tonight to see if I can get some photos, the Balao is matching perfectly with your photos though. Ran into glass calm seas in the Sea of Japan, should have taken screenshots last night when I noticed the effect.


Also, I have installed TMaru's Tench class submarine, is there any way I can adjust her to sit in the water exactly like the Balao does with this mod?

I don't know how you get 11,000 miles with a Gato at 10 kts. At 10 kts I get a range of about 9,000 miles. To get a range of 11,000 I've to manually set the speed to 9 kts.:hmm:
Wish me luck that I don't run out of gas.

I do it every time I take the Gato out on patrol. The trick was that we (the RFB team) had to multiply every sub's max range by 1.15 because the in-game files read the maximum mileage in statue - not nautical - miles. I just completed a 50-day patrol from Midway to northwest of the Marianas and back (April 17-June 7, 1942) like this by cruising to the patrol zone at 10 knots, and then I calculated I had enough fuel to get back to Midway at 12 knots. I think I pulled in to port with about 5-7% fuel left. Heck, I could have stayed out on station even longer, but I prefer to patrol my assigned area at ahead 2/3rds (7 knots in RFB).

You just gotta do the math and realize how far you can extend your fuel before having to head back to base. Do some thinking about how to best approach your patrol assignment, and you shouldn't have any problems with running out of fuel.

Just be prepared for some very short patrols in the S Class, though, as I'm sure AVGWarhawk will tell you...

Did the RFB team ever decide on a actual crush depth figure for the boats? If not you can ping off 400ft test depth and 925ft crush depth on the Balao and Tench Class (thick skins) undamaged. The other boats (thin skins) could use the same ratio working from their test depth. I haven't found any info on thin skins boats yet.

It's getting confusing... Is all the advice on speed settings (for example, Standard as best for fuel conservation rather than Ahead 2/3), or specific speeds in knots, based upon RFB?? I use only stock plus RSRDC...no RFB, No TM.

[399nkov]

Hello Doolittle81; When I first played sh4 stock I remembered reading somewhere on the forums that a specific speed of 10.5kts, on long hauls, would give the best range. I started using 10.5kts and it proved to be best for me. In really bad weather the speed would drop one or two knots.

I started using RSRDC, all ROW files, NSM and things remained about the same.

When I started using TM the speeds at different bells dropped a little and 9.5kts seemed the best.

I haven't tried RFB yet, waiting for the latest release. I'm sure it will be right on the real deal.

Hope that helps and not to confusing.

Thanks for the response. I also use RSRDC, all ROW, and NSM...so I'll follow your advice and cruise at 10.5Knots.

We're playing with this, but a number around 1.66 to 1.75 times greater than test depth is a fairly reasonable number because of the known safety margins built into calculating the test depth.

The best people to ask are the ones sending the mod out (on this one, LukeFF or me), others are just guessing unless they've poked into the range numbers in the corresponding *.sim file.

In this mod, a std bell will give you close to the ideal cruising speed for range. Vary it by up to one knot less if you want to see if you pick up any more range. Any more and you'll lose range. Any speed over a standard bell in this mod will definitely cause you to lose range.

It's the reason for the comment on the first post about the fact the std bell speeds were adjusted and why.

[silent killer]

Thanks SWDW for the mod and to those that tested the mod . Will try it out

@339nkov

in "thunder below" fluckey states test depth for gato-class was 312' and 438' for thick-skinned boats.

2 questions for swdw or anyone in the know -- i apologize as they don't have much to do with surface profiles etc. --
does your boat take damage when below test depth but above crush depth?

should balao-class boats have more hitpoints/higher armour reflecting their ability to take more of a depth-charge pounding?

I'm sure the depths were rounded off. Key here is, the enemy didn't know our newer subs could operate that deep.

Question 1- no, this has to do with the way the game is coded. And unless there's something wrong with the hull, it shouldn't. There was a considerable safety margin built into the test depth numbers.

Question 2- they do

On a side note, I found that the boats have a setting in the zone file for crush depth. So will start playing with that number and see what happens between it and the test depth setting.

The Balao has a crush depth rating of 787 ft in the zone file. Depending on what the results are, there may be more changes in this area.

Looking at those files, the hit points for each sub probably need to be cut in half. They already are in my RFB work, but that's only for the internal compartments, in the UPC files. These zone files cover the hit points for the hull. Just something you may want to look at when you decide to tinker with these files.
