Welcome to the family- having been in your shoes about 5.5 years ago, I know how you feel. As you can see, the HOF is a great place for knowledge sharing. Find someone in your marina who has a Hatteras or similar boat and can serve as an informal mentor to you. Someone you can go to with questions when you have that "am I about to screw something up" feeling. You'll continue to have questions and frustrations, as you interface with these amazingly complex systems. It's overwhelming at first, then as time goes by, empowering as you begin to learn each system and figure out how to do each task.
I also recommend keeping a meticulous log of everything you do- including some "process notes." That has helped me to remember not only when I did stuff but for things I don't do every day, how to do them the next time, including what products (e.g. paints, varnishes, filters) I used. Take pictures of complex stuff before you take something apart so you have a visual of "what went where."
I could ramble on but will stop there. It's an honor to be a steward of these wonder vessels. Enjoy, and we look forward to hearing of your experience.
