AB Yachts and Guido de Groot have collaborated previously on a handful of megayachts, including AB116 models. Two examples: Musa, built in 2010, and Blue Force One, built in 2011. As for Diamond, she features the same overall emphasis on indoor-outdoor living, with a brightly punctuated decor. Vibrant tones for accessories add pop to an otherwise beach-house-cool cool, mostly white interior. Highlights of the layout include a two-level saloon, an AB Yachts tradition, as well as a full-beam master suite and three guest staterooms. A gym is also aboard, though if extra guests arrive, it can convert into a twin stateroom.
