The history of the History Of Port Orchard Yacht Club includes a shot of a boat much like the Concordia the League passed whilst abaft, aport, afloat, or whatever it was. Here is another shot of a boat of the same name and similar design dating to the first half of the twentieth century.
On careful review of the pair of pics, employing my art-historian’s eyes, my tentative conclusion is that aye, the Concordia we passed is a) a survivor of the Moskito Fleet b) formerly the property of a burgeoning social club based in Port Orchard (!) and c) depicted in all three photos herein linked. $1k for a boat! My word!
