how can you get hull repaired?

well thanks to everyones help i came to realize i was very confused and incorrectly thinking i should be able to dock at any friendly port to get repairs.

i have been playing silent hunter for years but without a lot of spare time to play i only played the single missions so this campaign stuff is all new to me getting refitted and docking and all.

i finally figured it out that you can only get boat repairs and or end your patrols from pearl.

all other friendly ports just rearm and refuel your boat.

1 last question if you will - am i guessing correctly that any port you select to use as your home port would allow you to dock and make repairs the same way you do at pearl or is pearl the only repair dock?
