I have seen some comments of yachts.
When you have a boat there are only two happy days:
- The day you buy it and the day you sell it.

I don't think this means what you think it does.
You are happy when you buy a boat because you'll be experiencing new stuff which you haven't before.
You are happy when you sell it, not because the boat was a pain in the ass to maintain. It is because you have what you wanted from the boat and you are happy with the memories you have. I haven't been there done that but I imagine it makes the person even happier because you get some extra cash too by selling it.
If a person is happy just because he is getting rid of his boat, he either bought the wrong boat in the first place or he is simply bored.
I can't imagine myself being happy for selling my favorite toy.
Of course you enjoy it, but it's a constant ruin.
Mooring, revisions, a lot, a lot of fuel, the sea spoils everything, it is very beautiful but in the end you sell it and buy a smaller one if you like the sea, a powerful outboard more than enough, to go diving or do water skiing with your friends and your girls.
