At the moment I play on quite a low setting, I find it a good way to learn all of the settings and controls. It also keeps my stress levels down

I have just got my brand new boat and don't want to start this career again.
Is there a way of starting again with a new captain and real navigation so that I don't feel like such a god damn cheat
So can I keep my old Captain and boat but start a new career on the higher settings, I hope that makes sense.
