The 1966 Sparkman & Stephens (S&S) One Ton design represents a definitive era in offshore racing, marking the transition from heavydisplacement traditionalists to the performanceoriented "level rating" classes. At this juncture in maritime history, the One Ton Cup had recently shifted from 6meter boats to offshore cruisers rated at 22 feet under the RORC (Royal Ocean Racing Club) rule. This specific 1966 design—most famously embodied by the legendary Rainbow II—was a masterclass in balancing heavyweather stability with a hull form that could excel in a wide variety of conditions. Built primarily of wood, aluminum, or early coldmolded laminates, these vessels were designed before the extreme "distorted" hull shapes of the later IOR (International Offshore Rule) era took hold, resulting in a yacht that is as aesthetically pleasing as it is seaworthy. The design lineage of the 1966 One Tonner is perhaps most significant for spawning the S&S 34, a production yacht that became one of the most respected circumnavigators in history.
