If you're talking about the "Trade-In" link on the top of the page, I'm pretty sure that's just a way for Supra to get your info over to a local dealer. My guess is that you would then go through a trade in process like any other. IMHO, if you own the boat outright, you'd be better off selling to a private party. I haven't hear of many people being happy with the value placed on their boat/car/motorcycle, etc. when going the trade-in route.
