I would say advertise it here. I think it's nice when people give the members here first crack at it, but of course that's up to you.
In general, I think what's important is a clear ad, with good photos.
To expand on that, here are examples:
Not great as a potential buyer:
1975 XX 35', has radar, plotter, good engine.
Then you have like 5 blurry photos of the boat, which is strewn with the current owners possessions. And nothing with the engine room, bilges, steering gear, etc. Or maybe one top down photo of the engine (photo taker didn't even bother to go into the engine room).
No price.
Much much better (takes a little more work and time, but then with the type of ad above, I always wonder how much time DID the owner put into maintenance, etc. if they only put 20 minutes into the ad).
1975 XX 35'
Radar (brand and specific model)
Plotter (brand, specific model, size)
Engine: Year and model, if any non-regular type work done, specifics. If rebuilt, explain what that means.
Etc. Etc.
Specific price, location of boat, etc. all clearly delineated.
Lots of photos, in which the boat is clean and you can see everything (not the owners dishes, toothbrush, etc. which isn't what you need to see). Including photos all around the engine room, the steering gear, the cabins, the decks.... etc.
As a buyer, the second type of ad gives me something clear to look at. I don't feel like I have to beg for details. I know whether the electronics are ancient or newish.
Really, just having a boat clean and mostly empty of personal stuff is key. That probably sounds obvious, but I can't tell you how many boats for sale show a boat so full of stuff you can barely see anything!
I think people WANT to find a boat to buy. So show them what you have, clearly, with all the info, and they likely will.
PS: I'm sorry to hear about your Dad. It sounds like he had a lot of quality time with the Albin, and now he has good family looking out for him. That's gold.
