Amsterdam-based studio Dutch Design has shared an update on the build of its 42.5-metre Sea Rover project, which is billed as "the world's only wellness-first" superyacht.
The design was first unveiled in January 2025, created in collaboration with superyacht owner Scott Blum and Dutch designer Bernd Weel, known for the BOAT International Design & Innovation Awards winner, Lady Fleur. Intended as a "limited semi-custom series of just 10 vessels", Sea Rover was conceptualised by Blum, who was "unable to find a yacht that matched his desire for a healthy, balanced lifestyle".
The duo later employed Dutch studio Diana Yacht Design to collaborate on the naval architecture and Californian designer Paula Bruss on the interiors.
The superyacht entered construction in September last year, with the new build now reaching a construction milestone with the joining of the aluminium superstructure to the steel hull. According to the studio, interior production, engineering development and full-scale mock-up evaluations also continue to progress in line with the yacht's anticipated April 2028 delivery date.
“Seeing Sea Rover reach this stage of construction is particularly meaningful because it marks the realisation of an idea years in the making," said Blum. "Having spent much of my life aboard yachts around the world, I knew there was an opportunity to rethink how life at sea could support wellbeing and longevity. What began as a personal vision is now taking shape thanks to the dedication and expertise of an extraordinary team, and I couldn't be more excited about what lies ahead.”
The yacht is characterised by an abundance of onboard wellness amenities, including a spa, gym and sports court visibly positioned on the bridge deck, rather than on the lower deck (as is more common). The spa is designed with a dual-temperature plunge pool, a Jacuzzi, sauna, infrared therapy wall and dedicated massage area, while the sports court can be configured for pickleball, basketball, paddle tennis, volleyball or outdoor workouts. It can also be used as storage for large water toys, tenders and a car.
Accommodation is across five cabins, including a full-beam owner's suite located on the main deck. This space incorporates "one of the largest closet areas in the industry", according to the designer, as well as a Japanese onsen-style tub and steam room. There are further quarters for nine crew – separate from the captain's cabin on the main bridge – with all crew accommodation finished to the same standards as the guest cabins.
The interiors reflect an "intentional approach to living at sea", with a focus on comfort and wellness. Paula Bruss worked closely with Dutch Design to curate an "organic material" palette with a warm yet neutral atmosphere inspired by both Dutch minimalism and coastal California living.
Joseph Giles hardware, Dornbracht plumbing fixtures, Moore & Giles marine-grade leathers and Loro Piana marine fabrics outside adorn the spaces, with wood, stone and earthen-toned textiles incorporated throughout.
Key to the interior design is a central staircase, which runs through all decks and begins as a cubed glass table on the sundeck, refracting natural light into the lower decks. The dining space has a similar approach, with large glass panels providing sunlight and panoramic ocean views. This area merges seamlessly with an entertainment space and the galley to create a "grand room" that encourages interaction between the chef, crew and guests.
Another highlight is Sea Rover's sizeable beach club, which is arranged with a dining table, sunbeds, wet bar and ample storage.
According to the studio, Bernd Weel and the engineering team have prioritised simplicity and functionality throughout. Beneath the yacht's lines is a coordinated technical infrastructure, where piping, electrical systems, pump foundations and control panels fit within tight tolerances to integrate the interior and exterior architecture. As such, Sea Rover has been likened to a "floating, movable factory".
"Sea Rover is for an owner who likes to wake up and jump in the water; works out, goes diving, uses all the toys," Blum explained at Sea Rover's unveiling last year. "It’s integrating travel with total well-being – something that has never been done before on a boat. For those who become owners, this is a tremendous investment that will hold its value over time."
