The National Automobile Dealers Association makes blue book values for used boats available at its website, NADAGuides.com. The association provides online value guides for automobiles, motorcycles, boats, recreational vehicles and manufactured homes.
Pricing guides for high dollar value items that are often resold are referred to as blue books. Although these guides are most often associated with automobiles, they are available for vehicles of all descriptions. The NADA boat guide takes into account the year, make and model of the boat as well as the trailer and any optional equipment. The resulting price is based on the national average, so the price in an individual location may differ.
