Dutch studio Mulder Design has unveiled new details and renderings of its 70-metre superyacht concept Project Opal, which was first presented to the industry in 2024.
According to the studio, the design "reimagines luxury yachting" through a concept of Caribbean villa living: combining its proven hull platform (which can increase speed by up to 30 per cent depending on the engine package) with an interior philosophy that blurs the boundaries between yachts and coastal villas.
"Every element balances practical design with poetic inspiration," explained the design team. "The result elevates the yachting experience into art, where every moment feels like a gentle escape to a Caribbean hideaway that happens to float upon the sea."
Project Opal's interiors draw direct inspiration from these summer villas, with spaces decorated in weathered teak and leather wood for a maritime touch, rough stone for a costal finish and natural linen upholstery for a "villa authenticity".
In terms of layout, the design features several innovative systems, including an automatic wooden pergola system in the main deck lounge with a kinetic light installation that creates patterns like an authentic Caribbean terrace. Also in this space, there is a bar crafted from rough stone and worked wood, followed by a long teak walkway that divides two lounge areas with custom wave-pattern carpeting and low sofas.
Other "signature Mulder Design elements" on board include flared bulwarks forward on the upper two decks to improve vision and expand the owner's private forward deck space (from the dedicated suite). The provisional configuration also has a guest skylounge aft, though the studio notes that this could be reconfigured to transform the upper deck into a large owner's deck.
Six guest cabins are situated forward on the main deck, with the main saloon and dining area aft leading to a "multi-zone" aft deck complete with a bar, al fresco dining and lounge. As a result, the lower deck is dedicated to crew quarters. Up top, Project Opal has an aft sundeck area and hidden observation deck forward with a spa pool.
Closer to the water, a beach club at the stern features glass doors opening to a generous swim platform and large transformer platform. A transverse garage also accommodates tenders and toys.
"With the exterior styling, what we have aimed to achieve is a look that appeals to a lot of people and therefore isn't something too crazy, and which mirrors current trends in a way that isn't so super-modern it would date quickly," explained Bas Mulder, owner of Mulder Design.
"The core attributes are calm and elegant lines that work in harmony with the marine environment rather than screaming for attention," Mulder continued. "The project's organic lines follow the flow of waves and clouds, and the yacht looks like she was sculpted by the wind."
Last year, Mulder Design shared another superyacht design with BOAT International, the 28-metre concept known as the Onyx 92.
