Welcome Aboard!
At each port there is an anchor. Your home port has a anchor that is
tilted. You can only refit there.
I see you've already found the SH4 section. You'll get the best results asking questions there, and please feel free to ask all you want.
As for posting in two different forums, there's nothing wrong with that at all, as long as you don't put the same question in five or six. Then it gets our attention.
