Hi.
This is my basic crew for type VII in the year 1939:

All officers have 3 qualifications, depending on their position. The po have one qualification. All have the lowest rank and the lowest experience, because it´s the beginning of the war.
I changed the basic crew.cfg´s for type II and IX, too. They are basicly the same. Type II has no po for the deck gun and only two guys for flak. Type IX has just 4 guys for the flak - the other two guys are sent to diesel and after rest room (repair team).
In nearly future i will to change the crew cfg´s again to get more experience/ranks but lower qualifications when i start a career later. This will be done by the commander.
I play without fatique - because as commanding officer it´s not my job to manage my crew.
