But one thing is for sure - the vast majority of boats that you will see have been on the market a long time and will remain on the market a long time.
And if I can add one more thing to that... Most of those boats need a lot of work, even the ones that are still being used regularly. At least that's what we saw.
We saw three boats we really liked. One got scooped up a day or two after we looked at it. The other two are still on the market. Both of them are very well cared for, but both are 30 years old (one a Tartan and the other a Sabre). The one that got scooped up was an '88 Ericson (5 years younger) that had many recent updates and was the lowest priced at $57.4K.
There was another E38 that is listed for $12.5K more that was in much better shape than the one that sold and is 1 year newer. Yet, that's still for sale. So it must be the price. But if you go to Yachtworld and look up E38s, 1988 and newer, most fall into that mid to upper $60K range. NADA and BoatUS value them in the low to mid $50K range.
If you look at that little snapshot you could say if you want your boat to sell quickly, start with NADA and BoatUS values and take it from there. If you don't care how long it takes, use Yachtworld for values.
