The yacht One, formerly known as 111.11, is built on the technical platform of Lady Lene—a proven and successful vessel that combines the practicality of an explorer yacht with the luxurious comfort of a superyacht. However, the Dutch shipyard Van der Valk, renowned for its boutique approach, has once again redefined the boundaries of customization. Comparing the 2 vessels side by side, it's difficult to identify their shared origins—both externally and, especially, internally, they are entirely unique.

The design and naval architecture of both yachts were crafted by the same team: Guido de Groot, Ginton Naval Architects, and Diana Yacht Design. Van der Valk’s project department openly acknowledges reusing the engineering packages and hull design of the original vessel. This approach optimizes construction time and costs. However, they emphasize that above the waterline, every subsequent yacht of this type and size offers complete freedom for personalization—and Project One is a perfect example of this philosophy.

With an overall length of 34.13 meters, a beam of 7.80 meters, and a draft of 2 meters, One is constructed entirely from aluminum, keeping the displacement under 295 tons. This lightweight design, combined with a round bilge full-displacement hull and a hull vane at the stern, delivers excellent performance and fuel efficiency. Powered by two Volvo Penta engines of 750 hp each, the yacht achieves a maximum speed of 14.4 knots and a cruising speed of 13 knots. In an economical mode at 10 knots, with its full 31,020-liter fuel tank, the yacht boasts an impressive range of 3,870 nautical miles.

The exterior by Guido de Groot Design exudes modernity and dynamism. Sharp horizontal lines of the decks and glazing stretch forward, complemented by the angled window mullions and interdeck supports, all oriented toward the bow. A striking black-and-white color scheme further enhances the sense of motion, making the yacht appear to surge forward even when anchored.

Every deck of One has been meticulously tailored to the owner’s specific needs. Despite her compact dimensions, the yacht is designed to host large parties. Every square inch has been optimized to allow guests to interact or relax in privacy as well to provide the storage for an impressive array of water toys.

The upper deck is a mini-resort, featuring two sunbathing areas with loungers and a jacuzzi. Under the hardtop, there’s a bar with a barbecue station and a spacious sofa with a fold-out table for alfresco dining.

The bridge deck offers additional sunbathing areas, including a fixed lounger and a C-shaped sofa at the bow, as well as free-standing loungers at the stern. Beneath the overhang of the sundeck, there’s a dining area with a kitchenette. By opening the sliding doors of the upper salon, it is possible to create a seamless space for parties. This salon is furnished with cozy seating and a round table, perfect for games or casual dining.

The aft section of the main deck features a surprisingly spacious cockpit. It is connected to the swim platform by dual staircases. Sliding open the floor-to-ceiling glass doors leads to a bright and airy main salon. The layout is traditional, with a lounge area and a dining space, but the design is anything but ordinary. Rounded shapes dominate the interior—curved chairs, sofas, tables, cabinets, and even the ceiling’s oval relief, complemented by an elliptical chandelier. Every piece of furniture is custom-made. “We created a futuristic atmosphere on board One that transports guests to an otherworldly yet welcoming environment,” explains interior designer Carla Guillem. “This effect was achieved through the use of smooth, rounded shapes with an organic geometry and a carefully curated monochromatic palette that exudes freshness.”

The same design language extends to the spacious owner’s suite at the bow, which includes an office and a walk-in wardrobe. Below deck, there are four guest cabins—two with double beds and two with twin beds, each featuring additional Pullman berths for families traveling with children.

Berths for five crew occupy the bow part of the yacht. A unique feature is the owner’s walk-in wardrobe with a chute that leads directly to the laundry on the lower deck.

The aft garage houses water toys and jet skis. When toys are deployed, the garage transforms into a relaxation area with direct access to the swim platform.

One received glowing reviews at the Cannes Yachting Festival and won the prestigious World Yachts Trophy in the category of “Most Achieved Yacht.”
