I have made some investigations and it seems that wind force will have no noticable influence for dead reckoning. There are of course some special situations when wind force will be a term to consider but for navigation purpose it is neglectable (in my opinion).

But the ocean currents are still from any interest. There will be no differentiation of surface (depth = 0) and subsurface currents because we can assume that for our depths the vector is constant.

Here is an example of ocean currents. As you can see, there are a lot of currents and it is obvious that currents of 2kt in the canal will have influence when subsurfaced and we saunter with electric motors to hide from the evil enemy. So we have to consider carefully when to dive because our battery capacity will expire much quicker. Maybe we have to choose against an subsurfaced brake through and wait for the night to sneak past.

Take a look at the map:

I still don't know how to implement external forces. Any suggestions yet? (There must be some senior modders who can give basic information!).

Greetings to you modders out there!
