Thank you! That is a great checklist. I have a marine electronics person accompanying us on the sea trial.
I was active in marine training in the early 2000's (thus the "SeaSkills" which partnered with TrawlerFest prior to PMM). I re-entered Corporate America and have been dormant for the past 15+ years. I'm now ready to retire and head off cruising. A few things have really changed since then - Electronics is one (access to weather forecast products being another). Sure, move from NMEA0183 to NMEA2000 is now more or less complete, but what's most interesting to me is the number of wireless networks now aboard a boat. A good friend purchased a 3-year old Horizon 52' power cat a couple years ago that had all sorts of goodies running off a fixed-mount iPad, including a very sophisticated A/V system housed in an electronics rack, similar to what you'd find in a data center. If I had to guess, the previous owner spent at least $150k for everything from auto-raise blinds to sat TV (with 4 monitors). There are a ton of IP Addresses on the boat and at least four routers (one of which we've never been able to find despite a deep-exam into ceilings). The system has never worked 100% properly, and takes a network whiz to figure out the various networks and passwords, what is configured where (example, the blinds can have an independent router or can be configured as a sub-network). He tried having a Victron auto-start for his generator installed - Victron gear is now mostly WiFi controlled and it's network more or less usurped his primary wireless network and everything just stopped working (he ultimately returned the Victron and installed a Magnum which is analogue and works like a charm). Just finding someone to work on it has been difficult and very expensive.
Your prospective Selene is not that large and quite a bit older so it may be a non-issue. But try to be really thorough in making sure it works correctly, and interoperates as represented. If engine controls are interfaced to MFDs, make sure it works properly, etc.
For the anchor, at some point, run-out the entire rode to make sure it's in decent shape and not rusted into a ball.
For engine, there should be
no fluid leaks of any kind. No white fuzz at the heat exchanger or raw water pump. No oil weeps at the valve cover gasket. No water in the bilge. There is no reason a fiberglass boat should not be dry.
Good luck! Nice boat
