Boats. Yachts. Once a person gets one they can't stop thinking of it. It steals their free moments and their concentration. You can't think of anything else. You have fallen in love.
But a boat is different from a lover in that is not hidden. A boat makes a siren call to you and everyone knows it. Or should know it.
Linking poor performance to yacht purchases is a well known phenomenon. See Slate: The CEO Bought a Yacht?: Then it's time to sell.
I mention this because the Florida Marlins fired Ozzie Guillen as their manager after one dismal year.
Last fall after the White Sox let him go, he talked about buying a 62 foot boat then the Marlins hired him. And he got his boat and his Miami dock slip for the boat. And the Marlins had a horrible season.
This should not have surprised anyone.
