Simple question plus pro navigation quesiton in here

[bstanko6]

the game sends you to a zone for 24 hours just to send you somewhere. You dont have to follow that. In the DEF we usually get a 2 week patrol.

Your second question.

First, being submerged you will not intercept anything because you are too slow. You have to surface, and either start the 4 bearing method, or stalk your target (run parallel in an attempt to find course and speed). Once you have the course and speed, you can now plot out your "ATTACK COURSE".

The 90 degree method is solid, so if your target is traveling say north 0 degrees, then you have to attack the ship at 90 or 270 degrees. The real challenge is figuring the target ships speed out so you can plot where he will be in a certain amount of time. Once you have this, you can calculate what speed you need to travel to successfully overtake him, and be in a forward position of his track when firing the torps.

And you are wrong, 1500m is not where you want to be, go for inside 1000m. This will eliminate errors from your calculations. And attack at night!

Ill send you a link on how to.
