The International 600 is a distinguished 36foot classic yacht that represents a pinnacle of midcentury wooden boat building. Designed by Robert G. Henry Jr.—a naval architect whose pedigree includes work with the legendary firm Sparkman & Stephens—the 600 was marketed by the East Coastbased International Marine and built primarily by the De Dood & Sohn shipyard in Bremen, Germany. Often described as a "threequarter scale Concordia," the International 600 was conceived as a highquality racercruiser that could offer the seaworthiness and aesthetic of much larger yachts within a more manageable 36foot frame. Unlike the West Wight Potters produced by the Californiabased International Marine mentioned in builder archives, the International 600 belongs to a legacy of bluewater traditionalists, characterized by its full keel, graceful overhangs, and exceptional timber construction.
