Like most things, if you give it some though on the front end and work at it, it's a nice way to get access to a boat. I have had a number of partnerships over the years and really haven't had any issues. Think through how you're going to handle maintenance, fluel insurance, purchasing new items for the boat, fixing old or broken stuff, etc. Is it better to own a boat solo? Could be, but when you're paying 1/2 as much for new equipment, it starts to look a lot better. Like a marriage, it really depends on the people involved and what their expectations are. To dismiss the possibility out of hand and say, don't do it, it will never work because it didn't work for me or I knew someone who it didn't work for is foolish. Plan carefully and take it slow and it can be a great experience.
