Oh yeah, the Type II.
I got a lot of love for the Type II. It's a scrappy little underdog.
However, as you have found out, it is really not suitable for a first time player. Makes everything so much harder.
You're battling the limitations of the boat and trying to learn to play the game at the same time. Can make life very frustrating.
My advice, pick a Type VII. You'll love it. It's got range, firepower and speed. Great boat to learn the game in.
It's been a while since I played stock, but I'm sure you can pick a starting flotilla that has type VII boats. Try career starts in the different flotillas, you should be able to get one in '39.
And welcome aboard
