How to...????

[merceg100]

HI...
As you can see I am new on this forum and in this game, I never played Silent Hunter before or any familiar game to this one so the stupid questions that I'm going to ask will probably be emberasing to me but I can't help it
i finished school in Silent Hunter 4 and started career, they took me to some Philipino island and told me to observe some route until one Japanese island, all of you know that is beginig of the career in 1941... My questions are: Ploted course says that ETA is 227 hours!?!?! OK it is a great distance, but is there anyway to speed up real time or what? When will I intercept enemy ships or will ever (how often do you intercept them)? Is it beter to stay on the periscope depth (so not to get noticed, maybe there is better chances that theya will show up if they cann't see me) or go on surface? Why cann't I turn on RADAR while surfaced? I have tons of other stupid questions but they come to my mind right now, I'm really sorry but if you could help me a little bit I would appriciate it, I know that for some of you will be really pis*** off on me, but all i can tell you is that I'm a begginer as you were some time ago, so if you could please help me... thnx
