dude,
welcome to subsim.
if you want to drive a Type XXI boat you will have to play OpMonsun (OpM).
this is advanced SH4 so be prepared for some challenges.
on the way to playing OpM you will need to learn how to use JSGME to manage the mods (organized changed to the base game).
here is the link to OpM. Fifi is the current lead guy for that mega-mod.

here is the link to the current version of JSGME.

if you decide to play OpM, you will need to use the ATO Forum which is a subforum to this one.

Good Luck, and Good Hunting.
