They care for more than 10 Concordia yawls in our harbor, mostly 39's like this one. These owners stick to tradition. Any upgrades(few) are cleverly hidden. I've met the owners of this one, a very friendly couple in their 50's, attractive, athletic-you might expect them to own a new racing boat. They live in Southern Maine and keep the boat down there, but move it to Penbay for about half the season to race and coastal cruise.
The Concordia's I see are very well cared for and that care is intensive and not cheap. Similar to Hinckley, the owners are loyal and dedicated to their boats care. Boat care is an industry here.
Heres' the deck. Like many(most?), the ground tackle set up is 1950's. These boats almost always had chocks for anchors-rodes on deck/cabin. This one still has the Fishermen anchor but has gone to a Fortress for better holding and easier use. Either anchor and rode is manageable by hand(no windless on most of these 39's).
Originally these boats were raced and used on weekends. Anchoring was the exception. Today, most of them are still used that way - coastal cruisers, when not racing.
The only other upgrade I see are self tailing, bronze winches. I think I would lose the Fishermen anchor as the deck space on this 39' boat is wonderful.
