prices
As Peter recommended, contact a local broker who has access to the "sold boat" data on Yachtworld. He/she should be able to print you out a decent list of actual solds for a given area and/or time period. While it's not perfect and depends on accurate and timely reporting by brokers and dealers it's probably the best data set out there right now. Condition is everything and will have a large influence on price, oftentimes much more than equipment. A good strategy is to take the top few highest and the bottom lowest, throw them out and average the rest. That should at least give you a good feel for what they sell for. Many boats that were used heavily in the Caribbean charter fleets tend to get sold in the south which tends to drag the average down in that area so just keep that in mind when working numbers. By contrast, boats up north tend to get less use per season and that tends to be reflected in selling prices. Many years ago (before Yachtworld) most brokers in the country used the BUC multi-list system and reported sales to them so that they could compute and publish average sale price data. Nowadays I'm pretty sure that both BUC and NADA depend to a great extent on some sort of formula based on new boat msrp and a depreciation model to come up with their figures. Long story short, they don't seem to reflect real world selling prices as well as they should sometimes.
