Thanks, CB, that was what I was missing. I have figured out or by your dircetion now can destroy all the files where rules are available.

But, the rudder resistance thing. I open it in a hex editor and see rudder drag A0^ (not these exactly) so wonder what i need to edit or how the tools can work without rules.
Are there more rules I do not yet have?

I also will only want to barely tweak the rudders. As it is now they can turn just a bit too well and even a little less would make a difference.
My desire is to make this much harder on player but more realistic with a more reasonable chance good actions can result in survival.

So which tool does the rudder and how? This should be enough for me to complete my tweaks.

I am also thinking some of the convoys span too long a time distance.
Some run for early 42 to the end.
I will play with copying the entire convoy, adding it to the bottom with a new group number and ending the original Dec of 43 and start the same renamed one Jan 44 with more escorts (and different) for the later version.

Am I missing something with such a simplistic approach?
