It might not seem like it but this is a tough question to answer. Prices vary by model year, quality, location, sail inventory, engine hours, even by motivation (either seller’s or buyer’s), just to name a few things.
We don’t get into pricing but can tell you brokers have access to an MLS which includes the actual sale price of boats (not the listing price). Boats on Yacht World are for sale through brokers and, in many cases, priced with their input. This input will often include past sales plus some room to negotiate.
There is also NADA guides which can help as a guideline (https://www.nadaguides.com/Boats) for many boats.
Sorry we can’t be more specific, hope this helps a little.
