Course Plotting
 

I would like to know How exactly do you plot a course in game from point A to point B. Or do I just stick with using to way points? I want to be good at course plotting. Also I would like to know the best tactic for taking on enemy ships in raining weather or foggy weather when visibility is low and all I have to rely on is instruments. Any suggestions would be greatly appreciated. Thanks.

Sub school in the game has that laid out. pretty easy. You just make "waypoints" out as far as you want to go. Be sure to check for Islands in your path.

Attacking in rain, etc.: obviously you need to get closer. I have found around 750 yds. (+/-) you can see well enough to get the job the done. And, if they are hard to find, your periscope is harder.

you've been here since July 2009, are you asking about a different game?

Basic Captain techniques
 

I made a video some time back that covers aspects of course plotting and many other seamanship practices. Its quite long but it covers a lot. So much information that you may have to watch parts over a few times to grasp concepts.

For attacking in bad weather (that's GOOD weather for the submarine), ze doktor prescribes taking zis video und call him in ze morning:

And why can't we actually paste videos at Subsim? I'm used to being able to embed videos in forums.

In reference to setting a course, what alternative do you suggest, just setting a heading on your compass and going? That doesn't work in the game for some reason - I'd like to say that it's because of using a Mercator projection for the game map. Regardless of the reason, you can observe from setting a distant waypoint at a different latitude that the autopilot will have to correct course along the way (you can see it flipping the rudder a little every so often). IIRC, it usually has to keep readjusting in a more polar direction, ie if you are going Southwest it will be repeatedly turning left a little b/c it keeps drifting north of its intended endpoint. I would have to recheck (haven't simply played in a while), nor am I sure quite what would happen if the course crossed the equator...
