Hmm...since we assume the person receiving the advice is a new owner, and not a prospective one, this means providing post purchase advice. So my thought would be this:
Get all of the manuals for every system on that boat - the owner and service manuals. Then go through each system individually and learn as much as you can about them, while you inspect and take stock of what work or maintenance needs to be done to each of them. This will take some time, but when you complete such a review you'll have a pretty good understanding of your boat, its systems and their actual condition, and a prioritized plan for maintenance and replacement to ensure safety, functionality, reliability, of your vessel. Your survey report (you had a survey done, right?), should be just a starting point.
