About Project Diana

Built by Heesen Yachts in 2027, Project Diana is a 55-metre steel motor yacht that represents the latest evolution of a proven blue-water platform. She combines a refined aesthetic with purposeful engineering, designed for owners who value both presence and capability across extended cruising grounds.

Diana accommodates six guests across dedicated staterooms, with an enlarged bridge deck VIP suite that provides versatility for private cruising and multigenerational use. Her design features a sharper silhouette with slanted wheelhouse windows for enhanced visibility, while the superstructure presents clean, continuous lines accented in Whisper Grey Awlgrip. The main saloon and skylounge benefit from reduced mullions that maximize the glass-to-metal ratio, creating an open connection between interior spaces and the surrounding seascape. A redesigned, personalizable mast and an integrated infinity pool on the main deck aft are defining features of this platform.

This yacht is suited to discerning owners seeking a capable, long-range motor yacht with contemporary design language and practical cruising comfort. The platform's blue-water heritage and refined proportions appeal to those planning extended voyages with an emphasis on both performance and refined living.

Bella Yacht assists buyers throughout the acquisition process, from availability checks and yacht analysis to negotiation strategy, survey coordination, documentation, refit advice, crew, delivery and post-purchase support. Our role is to help clients evaluate this yacht with clarity, compare it with relevant alternatives and secure the best possible conditions.
