If I make a deal and send a deposit on something and change my mind, I don't expect to get the deposit back. But, that's just me and obviously a lot of you don't agree with that. Did you guys have a deal?
I'm having trouble understanding why this guy would accept your deposit (or why you would send it for that matter), if the deal wasn't done pending a sea trial or inspection of the boat. There has to be more to this story.
To call this guy a deadbeat and bash him without knowing his side of the story is unfair in my opinion.
