Adagio was built in New York using Richardson’s WWII plywood technology, touted as the “Cruiser of Tomorrow”, and the hull was designed by Sparkman and Stephens in a 1943 contest. She was shipped to Puget Sound, which may account for her longevity. The Twin Crusader engines were replaced with Gray Marines in 1965. Minor upgrades have been done to the interior and systems, but her basic Sedan Cruiser design is retained.
