Looks like NADA dropped out of the used boat pricing business and J.D. Power picked it up. I could no longer Google "NADA Boats" and get any hits for a NADA web page/site.

https://www.jdpower.com/boats/manufacturers

Still there: https://www.boats.com/nada-guides/

Negative, that's just an article on boats. net. Links in article will not take you to a NADA web site.

Your right, NADA Guides boat values are one of the best ways for checking the prices of new and old boats. You can find the values of outboard motors, powerboats, sailboats, personal watercraft, and boat trailers with this value guide. J.D. Power is a leading provider of trusted vehicle/vessel valuations, and the owner and operator of NADAguides.com (which will rebrand to JDPower.com soon). J.D. Power has been delivering incisive industry intelligence on customer interactions with brands and products for more than 50 years.
