What do you think the price of a Cape Bay 31 should be over an Ericson 31? I don't see the value for the one listed in Seattle. Looks like 30% premium over an Independence. Is the Cape Bay really build that much better than an Ericson 31 Independence?
When you are looking at a 30 year old boat, the design and construction give it a "base value" but then the overall condition and equipment will add (or subtract) a lot from that base point. At that age, two sister ships can be 100% apart in selling price and both can be priced appropriately.
I have seen this in other well-maintained classics.
So, everything depends on the boat itself. No matter what price the seller wants or the prospective buyer wants to offer, the boat itself will have the final say!
Stated another way,
any particular Ericson I-31 or E-31C or Cape Bay 31 could be worth that much... or less...
If you were to research back on this site for selling info for Sean's former E-35-3 or Tim's Ericson, you would see that each sold quickly for absolute top dollar, and was a great deal at the price.
