Due for delivery in 2027, PROJECT DIANA represents the next evolution in Heesen Yachts’ renowned 55-metre fast displacement series. Crafted with precision and innovation, she combines the shipyard’s exceptional Dutch engineering with the artistry of Van Oossanen Naval Architects, Omega Architects and Luca Dina Design & Architecture.
Designed for owners who seek performance, comfort and high-quality craftsmanship, PROJECT DIANA embodies the spirit of modern yachting. Her impressive transatlantic range ensures she is as capable as she is beautiful, while her interior remains fully customisable, allowing a future Owner to shape every detail to their personal vision of life at sea. This exceptional yacht is available on a short delivery timeline, offering a rare opportunity to own a Northern European pedigree yacht without the wait.
Full Description
Exterior Design & Engineering
Omega Architects have sculpted PROJECT DIANA’s exterior with a bold, contemporary aesthetic that blends elegance and power. Her steel hull and superstructure are accented by sweeping lines and dark-tinted glazing, giving her a distinctive and sporting silhouette. Built to Lloyd’s Register and the Large Commercial Yacht Code (Reg-YC), she carries a gross tonnage of 760 GT, balancing sleek form with substantial interior volume.
Powered by twin MTU 8V 4000 M63L engines, each delivering 1,341 Hp, PROJECT DIANA achieves a top speed of 15.5 knots and a cruising speed of 12 knots. With an impressive range of 4,500nm, she offers the endurance for ocean-crossing voyages. Naiad stabilisers ensure comfort in every condition, both underway and at anchor, making her equally suited to coastal cruising or far-flung adventures.
Amenities
Spanning four decks, PROJECT DIANA yacht has been conceived to deliver a seamless connection between the indoors and out. On the sun deck, generous open-air spaces invite long days under the sun. Here, guests can recline, dine al fresco, or enjoy evening cocktails, backed by endless views.
The bridge deck continues the theme of openness, with a vast aft terrace ideal for entertaining, complemented by a foredeck that offers a private escape for quiet reflection or evening stargazing.
The main deck aft leads into a spacious salon where floor-to-ceiling windows flood the interior with natural light, blurring the boundary between sea and sky. An infinity-edge jacuzzi with inbuilt sunbeds creates a relaxed atmosphere on deck, while a wide staircase descends to the beach club. At water level, the expansive swim platform transforms into a launch pad for toys and tenders, or simply a serene place to unwind beside the ocean.
Interior Design
Luca Dina Design & Architecture have envisioned PROJECT DIANA’s interiors as a sanctuary of calm and sophistication. A palette of natural materials, soft cream tones and tactile finishes is complemented by earthy accents, creating a refined yet welcoming atmosphere. Every space has been conceived to feel timeless and personal, and with the project still under construction, the future Owner retains the opportunity to tailor the design to their taste.
Accommodation is arranged for up to 12 guests across six cabins, comprising a full-beam Owner’s Suite and five guest cabins. The Owner’s Suite introduces a truly transformative feature: a French balcony that offers a private, open-air connection to the sea.
