In the past 24 months there have been 10 brokered sales of W32’s with a reported average sale price of about $45k. This holds true looking back as far as seven years with over 30 sales, but the price is dropping naturally as you might expect 30 and 40 year old boats to do. With that said, Westsails have tended to hold closer to asking price (2% to 5%) than most other comparable boats recently. It is likely there have been a similar number of private deals. Five non-brokered cash sales which I have been involved with in just the past few years have averaged about $50k. These values are more or less in line with BUC and NADA depending on how you adjust the criteria, but those values have been steadily dropping over the past ten years.
In a broad discussion of valuation about one model of boat with a long production run you can pretty much discount the ugly ducklings as irrelevant unless they constitute a majority of the market. Enough people are maintaining and upgrading Westsails that the upper echelon boats are more of a factor when considering a typical or average fair market value.
In a few special cases I know hull insurance policies will be written for as high as $90k, otherwise a reasonably equipped W32 in #3 BUC condition can make a good case for $50k+. Of course this is no guarantee sellers will find willing buyers at that price point in any given market at any given time. Too many nice boats for sale at one time in one region will almost always drive the price down. Even in the most booming economy, the sellers of used boats do not tend to see a lot of bidding wars.
Boats always depreciate; very fast at first, then slower for a while and then fast again until they are worthless or antiques. Considering the first of the Westsails are now over 40 years old, they are doing relatively well but will continue to depreciate steadily no matter the economy, world politics or public perception.
If you want an investment: buy real estate. If you want to go sailing: charter a boat. If you want to own a boat… try not to worry too much about logic and just enjoy the experience.
