One of the earliest jobs I did on Red Ranger was replacing a hulking beast of a fan in the aft cabin. It was huge; with a wire cage and blades that had broken and were glued back together. Really.
This is kind of a mortuary shot after I had removed it in 2011.

I replaced it with this fan. A Guest 902.
Th old fan was was screwed onto the furniture. So I bought a fan that would more-or-less fill the same space. Which — perhaps — was less than ideal. Because it was LOUD.
Remarkably LOUD.
Maybe not quite electric drill LOUD. But louder than made sense when you're trying to go to sleep.
I would have been better in — maybe — the engine room to move air in there.
And.
Bonus. Because it was fixed on the furniture you could turn it through a small angle. And if wasn't pointing the right way. Well. Tough. It's main advantages were small and covered in a grill that a child couldn't get a finger through.
It was not terribly useful for us.

I've finally gotten around to "replacing" it. Which is not really a replacement, but more a recognition that two fans are sufficient when it's just us living aboard. CA realized we could save a few bucks by not buying yet another fan.
I moved this one from the V-berth.
I need to coil up the wire a little. It plugs into a 12V outlet. Which I added.
And in the process, cleaned up a bunch of crappy wiring I did when I was new to boat wiring. I used two crimp wire nuts instead of a much nicer terminal block.
I have to say, a ratchet crimper is something I should have bought 10 years ago.
