I'm glad you posted that. It will help me a great deal to be able to "drive" some surface ships around, and see how they behave.

I wasn't able to get them to work with RFB, so I will have to either figure out how to adapt them, or use GFO for some tests.

About the freighters; I would like to test a few to make sure they do what they are supposed to. Is it difficult to make ships playable? The only thing I really need, is for them to accelerate to max. speed, and check their turning. I'm thinking I need to try some of widely different sizes/speeds. If they respond ok, the the ones in between should be ok.

Yeah, I remember Duci posting about his stratagem. I think this may be the only way to get decent battery performance. When I'm done with the turning/moving stuff, I'll try to figure out how to get a special ability crewman in every boat. I've never done anything with that part of the game. (I still wished I knew why I can't just put in the right number into the file. )

On the draft issue, my understanding is RFB felt the boat sat too high in the water. What is your understanding of their thinking?

I seem to remember reading somewhere, that the widely varying figures for draft, displacement, and speed were due to modifications made to the boats over the years, but I can't remember where I read that. In any case, I don't think the difference would change much of what I'm working on. I've noticed that sometimes when I surface the boat will come up a foot higher than "normal" and get an extra knot, but if I mod the files to have it 3 feet higher, it doesn't change the speed. Whatever values we put in will be "normal".

Here is some information that I hope helps you out.

This one will open a PDF file that deals with certain aspects of submarine physics centered around torpedo avoidance of the submarine. Some information may be helpful in your search.

Here is a list of manuals and documentation:

Ah yes, those help. I like the '42 S-boat manual, good stuff.





Did some more experimentation today. I think I can start seriously nailing some things down soon. I have the S-18 pretty much like I want it. The diving and turning are much better. I think I can probably use the same numbers for the S-42. I should get easier as I progress, since I know more about these arcane details now.
