re: Was I in the wrong? (buying a boat)

They made it right AFTER you posted what you did.

If no deal had been made, then nothing would've ever been "corrected". They know they messed up, but nobody figured you'd slam them publicly about it. (the typical boat buyer isn't an avid internet reviewer / complainer)

You did right IMO, and they'll remember that moving forward. They shouldn't make deals and not hold their word.

I would've bought one somewhere else and posted about it probably.
