Delivered in 2017 as the very first hull in the Mulder ThirtySix series, she was sold through Mulder’s in-house brokerage department, with the yard continuing its close involvement in her ongoing management and technical upkeep.
Delta One was designed by Claydon Reeves with interiors by Vickers Studio and built on Van Oossanen’s FDHF platform at Mulder’s Dutch yard.
Inside, the superyacht showcases a refined and timeless aesthetic developed by Vickers Studio. Large hull windows flood the interiors with natural light, while the layout was carefully arranged to suit extended family cruising. She accommodates up to 10 guests across five cabins, with an owner's suite positioned on the main deck for privacy and panoramic views. The four remaining guest cabins are all doubles, making her well-suited to family use or charter.



Onboard amenities include a gym, full air conditioning, and generous social areas that strike a balance between elegance and relaxed luxury. Her interior design helped her secure finalist spots at the 2018 Boat International Design & Innovation Awards, including for Best Lighting Design.
The exterior spaces are thoughtfully arranged to enhance life on board. A generous sun deck acts as the social hub onboard the motor yacht, equipped with a spa pool for seven, a bar, sunpads, pop-up TV, and an outdoor dining area. The sundeck also includes a service bar with barbecue, icemaker, and sink, supporting both informal relaxation and more formal entertaining.



At the stern, a hydraulic bathing platform connects to the beach club, which is fitted with a 50-inch TV, dayhead, shower, and wet bar. This area doubles as a protected boarding zone, ideal for embarking on water sports or tender transfers. Twin staircases link this space with the main deck above, while a central transom door reveals a transverse tender garage large enough to stow a 6.25-meter tender, two full-size jet skis, SeaBobs, and dive equipment.

Guest accommodation aboard the yacht includes five suites: an on-deck owner’s suite and four double guest cabins below. The layout supports up to 10 guests in total, with an additional six crew members housed in dedicated crew quarters to maintain high service standards throughout any cruise.

The use of space is notably efficient for a yacht under 500GT, a key reason Delta One was awarded Best Displacement Motor Yacht Below 500GT at the World Superyacht Awards in 2018.

Powered by twin Caterpillar C-18 engines delivering a combined 2,300hp, Delta One achieves a top speed of 17 knots and cruises comfortably at 15 knots. Her range extends to 2,200 nautical miles, thanks to her 32,000-liter fuel capacity. Stabilizers fitted for both underway and at-anchor use contribute to a steady onboard experience in all sea states.
According to YachtBuyer Market Watch, Delta One was last asking €14,900,000.
