(WIP)Submarine Draft Fix
 

I have been working on a fix for the problem of incorrect position of the submarines in the water. I have been comparing Screen Shots of the subs, making adjustments to match the pictures of the WW2 subs I have collected from the net. Here are three composite pictures of the work so far.

I started with the stock game but I will have a version for RFB 1.52. I don't use TMO but I could easily make one if someone wants it. Once I get a draft number to match the photo, it can be used in any MOD.

The Balao Class- notice the two torpedo tubes out of the water in the Stock Shot

Good job ! :up:

Aren't those pictures taken with a full load of fish?? Compared to of being completely empty? The subs where terrible in depth keeping when moving slowly.

I'm very interested in a TMO version. Looks good. :up:

Hi There,
With or without fish makes no difference when the boat is in diving trim. Water is used to replace the weight of fish, otherwise she would never get down! When a torpedo is fired an automatic compensating system allows water equivalent to the weight lost to enter a tank. Likewise when a bow cap is opened she doesn't suddenly get heavy 'cos water is blown into the tube from said tank.

I ignored all the just after launch pictures and concentrated on the ones of the ships at sea and on sea trials. Those pictures are all similar with small variations due to wave conditions and ship speed. As a check I looked at post commission in port pictures to confirm the look of the subs in the water. The pictures I used are representative of that work and the clearest views to use. Many of the other photos needed manipulation to enhance the details to confirm my determination of the proper look. The seas had to be quite rough in order to show the top torpedo tube.

As a side note, the stock screenshots shown are similar to the post launch pictures taken after the buntings were removed.

For the screen shots I started a career when each sub class was available, calmed the sea and saved. I restarted the saves and took the stock screen shots. I loaded the mod and used the same saves to take the screen shots under the same conditions. I used FooBor's sub skins but compared the results with a completely stock skin set and saw no difference. PE4 was used because I could not get calm seas with the stock game setup for consistent results.

there have been a couple of these but so far it looks like it's the most historically accurate so far.

can wait to see it looks great keep up the good work

looks good but one note of caution, as you change the draft heights you will also change your range and distance do to increased fuel consumption and speed can also be effected as well as it relates to the drag settings. sitting a little lower in the water can have a big effect on the drag applied to your boat so it is very likely you will have to tweak the drag settings so the sub acts correctly. there is a certain height level that if you go below it will change the drag coefficient like you are decks awash and your fuel consumption goes way up. changing the drag coeficient is not a hard thing to do but it is easy to overlook this if you dont know about it.

do some testing to see if your fuel consumption or range is different than stock

Oh kewl. I was going to lower all the boats in my gun mod but for a different reason. The lower in the water you sit, the harder it is for you to man the gun station in bad weather. I only applied it to the Sargo so far and I am running around testing it now.

if you want guns harder to man in rough weather just change the storm conditions setting in the subs cfg file to a lower number and they wont be able to man the guns if conditions are above that number

Thanks Webster.

Will that stop the player from manning the gun?

Webster thanks for the warning. I had planned to test it thoroughly before releasing but I had not really considered the fuel aspect. Mainly because each of draft numbers I came up with put the subs slightly higher in the water than RFB, but I will look at it now to make sure. Multiple fuel expended over a certain time in the same conditions run will show any differences. Although if I get slightly better fuel economy in RFB I will be tempted to leave it be.:D

It would appear that lowering the boat a meter in the water has no effect on fuel consumption.

I lowered the the Sargo almost a meter and she went 5,000 KM at manual setting for 10 knots. Fuel left was 82/100.

I then ran stock with the same settings and got the exact same results.

However, it does appear that when setting your ship speed you get this:

Make revolutions for 10 knots.

As opposed to actually going 10 knots.

So when making revolutions for ten knots you get the same fuel consuption but maybe not the same actual speed thus the drag aspect.

Timing the two would require a mod of the environmental variables to see what effect lowering the boat would do to the time of arrival when making revolutions at 10 knots.

AFAIK there is nothing that stops the player from manning the gun but it will stop the crew from automatically manning the gun if ordered and during battle stations.
