You will almost always get more for your boat by selling it yourself. The advantage to trading it in, in most states, is you get to deduct your trade in from the amount of sales tax you pay.

(The dealer will probably want to tack on a $100 or $200 to do the deal, but its worth it.... as long as your state does not prohibit transactions of this nature)
