When it comes to boats and marinas, you can often throw logic out the window. As silly as it sounds, I'm convinced some people just like saying they own a boat, and are quite willing to spend big bucks to say it. After all, if you are going to take a boat out a couple of times a year, chartering only makes sense financially. I know a couple of guys that don't really like going out, but enjoy sitting on their boat in the marina environment. One guy occasionally takes his sailboat out in the morning to run the motor, and is always back before noon. The wind rarely comes up here before 1PM!
I think that there are also some older Skippers that don't want to let go of the boat, because of what it implies, even though they can't sail it anymore.
Others won't sell the boat for what it's worth because they think it should be worth more. They will let it sit and deteriorate while paying slip fee's and insurance until it's worth even less!
I can go on and on about the things you only see at marinas, but here is another good example!
