HEESEN LAUNCHES 50-METRE PROJECT SOPHIA
Heesen is delighted to announce that on Saturday, 14 March, YN 21150 Project Sophia, a 50-metre all-aluminium yacht, was launched at the facility in Oss.
Project Sophia brings a distinctive character to the 50‑metre segment, combining high-speed capability with the exceptionally shallow draft needed to reach some of the world’s most coveted anchorages. Defined by a formidable 23-knot maximum speed and a draft of just 2.15 metres the benchmark depth for unrestricted cruising in the Bahamas this all-aluminium platform is engineered for swift passages and the freedom to explore territories usually reserved for much smaller yachts.
Heesen’s naval architects achieved this balance through a refined hard-chine hull with recessed propeller tunnels. Beyond enabling shallow-water navigation; this profile delivers a l 12% gain in hull efficiency, setting a notably high-performance standard within the 50-metre class. At 499 GT and fully IMO Tier III-compliant, Sophia stands as a definitive example of Northern European craftsmanship and technical ambition.
Peter van der Zanden, Director Design & Development and Engineering, commented: “At Heesen, we believe that smart naval architecture underpins a yacht’s true value. With Project Sophia, our engineers have improved hull efficiency by 12%. This is more than a technical metric; it translates directly into lower fuel consumption and a quieter, more enjoyable experience at sea. The result is a highly optimised yacht that reflects our Dutch heritage of building for performance.”
Powered by two MTU 16V 4000 M65L engines, Sophia offers a transatlantic range of 3,100 nautical miles at 11 knots. The level of finish on Project Sophia reflects Heesen’s vertically integrated approach. By completing the entire interior fit-out at the shipyard’s dedicated cabinetry workshop in Winterswijk, Heesen maintains full oversight over both the production timeline and the meticulous application of precious materials. This contemporary interior is shaped by a palette of sage greens, mustard accents, and warm bronzes, arranged to create a deliberate sense of flow between the yacht and the surrounding ocean landscape. The main deck aft features a cool shallow pool with floating sun loungers designed to draw the eye toward the horizon.
Designed for active exploration, the beach club is configured as an activity-focused hub with tailored stowage for wakeboards and land-exploration bikes, opening directly onto a fold-down swim platform. On the sundeck, a sliding-door windbreaker ensures guests can enjoy these elevated social spaces in total comfort, even while cruising. Finished in a distinctive ‘Whisper Grey’ by Awlgrip, Project Sophia is currently available for purchase. Following her launch, the systems will be commissioned before she commences intensive sea trials in the North Sea, remaining on schedule for delivery in June 2026, perfectly timed for the summer season
