The Metalu Diam 40 was designed by the prominent French naval architect Michel Joubert (of the famous Joubert/Nivelt design duo), who was highly celebrated for creating exceptionally rugged, seaworthy offshore racing and cruising yachts. First launched in 1978, the Diam 40 is a heavy-displacement, blue-water cruiser engineered for transoceanic voyages and harsh marine environments. Highly regarded in the secondhand and-offshore sailing community for structural longevity. This yacht has certainly stood the test of time and represents very good buying for an alloy go anywhere yacht.
