Parents are selling their 2003 Crownline (no idea on the size, engine, etc). Step-mom asked me to help her find via Google a Kelly Blue Book type deal for boats. I cannot find such a website despite repeated Googling and I am hoping DoperNation can help. thanks!

Like other sites, you need to enter your ZIP code and some other bits and bytes.
