Project Diana - Heesen Yachts FOR SALE

Diana represents the newest evolution of our 55-metre Steel collection, advancing a proven platform conceived as a genuine blue-water, world-cruising superyacht. Her exterior draws a crisper, more assertive line, with raked wheelhouse glazing that heightens sightlines and adds purposeful poise. Clean, uninterrupted superstructure geometry sweeps from bow to stern, highlighted by Whisper Grey Awlgrip detailing across the mast and upperworks.

Innovations include a reimagined mast—a contemporary statement feature that owners can personalise with bespoke accent hues—and an infinity pool seamlessly set into the main deck aft. Slimmer mullions in the main saloon and skylounge boost the glass-to-metal ratio, visually merging the luxury motor yacht’s interiors with the surrounding seascape. The expanded bridge-deck VIP stateroom elevates the accommodation plan, delivering a flexible haven ideal for private cruising or charter itineraries with multigenerational families.

Diana melds a strong, athletic stance with practical enhancements that anticipate the evolving expectations of owners in the 55-metre displacement segment.

First impressions

Diana stands as the technical pinnacle of Heesen’s highly successful 55‑metre Steel platform, the culmination of Dutch engineering excellence. Built on a proven foundation honed by data from sisterships and direct market feedback, she appeals to owners who value certainty, uniting a dependable heritage with purposeful design updates that raise the benchmark for this class.

Her exceptional efficiency and low fuel consumption are born below the waterline, where superior hydrodynamics reduce environmental impact at the source. The patented Fast Displacement Hull Form (FDHF), conceived by Van Oossanen and refined by the shipyard’s engineers, delivers a remarkably slippery hull that underpins class-leading capability across all sea conditions.

Paired with MTU 4000 M63 (IMO Tier III) engines, Diana attains a top speed of 15.5 knots and couples fuel efficiency with notable stability, ensuring a smooth, comfortable experience for long-range cruising.

Step aboard

Diana welcomes twelve guests across six staterooms, anchored by an expansive 86-square-metre owner’s suite, complemented by four guest cabins on the lower deck and an enhanced VIP suite on the bridge deck. The arrangement privileges active, multifunctional living, reimagining the traditional beach club as a wellness-focused gym. Her interior, crafted by Luca Dini Design and Architecture, embraces a philosophy of naturalism and tactility, with a palette that shifts from warm whites to blonde-rust hues so that light plays with texture rather than bold colours.

Sustainability guides every material choice, employing Alpi reconstituted timber and honed marbles to achieve a refined finish with a lower environmental impact. Fluted and sandblasted glass introduce soft, diffused privacy throughout, while natural stone accents, including Rainforest and Camouflage marbles, lend depth to bathrooms and cabins. The result is an interior defined by precision and a layout shaped around how modern owners live.
