Welcome aboard. A great boat, which should serve you well for many years.
You might consider using an Excel type spreadsheet to collect the info about your boat as you gather it. Pics, text, and numbers are easily entered, and organized.
In the Library here, or on internet? is the databases written by the Captain of the Dirona, who has set them up for maintenence scheduling as well.
Even a notebook, with references to pictures will help. As you look at a system or part, record its' make, model, install date, and where to get more of them. Say a fresh water pump.
I also use the Msoft ToDo list as a place to make notes of tasks that I want to do, and what I need to get to do it. Undated, but otherwise I forget what I need to do next.
I keep one list with the numbers I may need on short notice, such as insurance policy number, Fed Registration number, MMSI number, dinghy registration number, etc.
If you dont have a copy of Nigel Calders' Boatowners Mechanical and Electrical Manual, get one, 4th edition, about $42 on Amazon. It seems to have something useful about anything that might be installed on a boat.
Have fun. JohnS
