How about the currents ?

Just one thought, not a new one: How about the currents? With a new weather model + celestical navig. ? "Groundbreaker"?

Modeled currents would indeed have to be a groundbreaker (and a most pleasing one).:hmm:

[Aside to any devs who may be listening: face it, we want it all!]

Any ideas how harsh it would be to do the current model?
On different sea area your boat would be moving to a certain direction with certain speed. Hmm... How is it in real life? Let's have an example:

There is a current going straight fm north to south at speed 3 knots per hour. A vessel is heading to north, speed 3 knots. How much the current affects in RL? The vessel is moving 3 knots contra water, but what could be the speed contra seafloor. I doubt it's 3 knots vs. 3 knots = 0 knots. Or is it? Then submerged sub should make 6 knots to reach even 3 knots contra seafloor. Can't be.

Sailors, please...?

The best example I can think of is Lombok Strait, where subs transiting between Fremantle and their patrol areas had to - IIRC - fight the current going to station but could drift with it coming off station. Its speed varied but I think it was about 6 knots. That, I think, is one of the fastest currents the boats had to deal with. Seems like I read about one boat making about 1 knot forward speed through there. I'll dig around and see if I can find the specifics.

Yep, I did some investigating too.
I did remeber it correct, so if you are traveling straight towards the stream with equal speed your speed will be 0 contra seafloor. Everybody can imagine what kind of affect the currents would have in your tactics.
For example, if you turn your heading in the stream after an attack, you'll get a big bonus to your speed, and in an hour you'll be 6 nm's off the point you lauched the torpedoes (if you are driving 3 knots and the speed of current is 3 knots also). So, DD's will be far away maybe, or not... If they can take this in account.

But anyway: More I think dynamic weather, celestical navig. and streams, more interested in I am. Navigation would not be a problem to a casual player, if the process is done by the navigator. (AI). There has been good ideas for the navig. system. Anyway I would like to get rid of the GPS-system.

This is actually an effect well known to pilots. When navigating in any kind of wind, wind speed and direction have to be taken into account, or you'll wind up miles from where you wanted to be. Flying at 90 knots perpendicular (right angles) to a 10-knot wind means that every hour you'll be another 9 (nautical) miles off course.

If your u-boat is submerged and making 4 knots against a 6-knot current, yes, you will actually travel 2 knots backward. Calculating the directional 'push' at any angle other than 90 degrees to your direction of travel makes the calculations much more difficult. Pilots at least have radio beacons they can use to triangulate their exact position.
