You need the main 6 the last guy said. On my sub i actually run with empty R slots
for less weight (putting anything in them slows me down some). If you want to put
anything in them, you have 2 gun slots. The guns are fun to use, but a rest and a
rep would be good for keeping you alive too.

thanks a lot man.

6 main sailors:
1 BO
1 engineer
2 torpedoman
1 sonar
1 planesman

then,
repair 0~2
restore 0~1
gunner 0~2(SS4 LV 74 GUNS VERY FUNNY)

thank you but, i was asking if this are these are the sailors i need or if i need any
other specific one for sub.

Check trainworld, they have a brand new ship page that tells you how many sailors each
ship can hold. Really nifty, as I realized I need to train another rep
