Trying to find a ballpark for what my boat is worth. Any website you can share or suggestions?

Kelly Blue Book for boats is the only one I know of. It typically is not in line with what the market is though, but if you are financing I believe that is what the lendors typically use. Kelly Blue Book doesn't account for all the misc electronics that typically come with a used boat as well as the sentimental value previous owner put on price tag. The other option is the scour classifieds such as Craigslist, Boat Trader and even the classified on TFF. The classifieds will give you an idea of what the market price is going for. Even posting a request in this Forum of basic specs of the boat will most likely get some responses to ballpark value. TFF is probably most active and informative fishing forum I have come across with some very sharp honest people.

Outside of personal watercraft (Jet Skis®), Kelley Blue Book doesn’t provide values for other kinds of boats. This also includes boat-related products like outboard motors and trailers.

This is what Marine Dealers and Lenders use.

They use NADA/BOATS. Keep in mind, these prices are for reference.
