The Macwester Wight Mk I 31 represents the quintessential heavydisplacement British motorsailer of the late 1960s and early 1970s. Designed by C.S.J. Roy, the founder of Macwester Marine, the Wight 31 was engineered to provide a safe, upright, and voluminous platform for family cruising in the challenging tidal waters of the English Channel and the North Sea. At 31 feet 3 inches, the Wight Mk I was a significant step up from the company’s foundational 26foot models, utilizing a robust GRP hull that prioritized interior living space and ultimate stability over raw speed. Its defining characteristic is the centercockpit ketch configuration, a layout rarely seen in vessels of this size, which allowed for a private aft cabin—a luxury that became a hallmark of the Macwester "heavyweight" philosophy.
