Nasiba Launches: A Pioneering Milestone in Health-Conscious Design

Winch Design is thrilled to announce the launch of Nasiba, the third hull in the 44-metre Flexplorer 146 series today at the Cantiere delle Marche shipyard. The highly anticipated explorer yacht is due to be delivered later this year.

Driven by the client’s deep commitment to health and wellbeing, this unique yacht features a bespoke interior by Winch Design that places natural materials and low toxicity at its core. Every element has been meticulously curated to support a clean-living environment, with low-VOC (volatile organic compound) materials and minimal electromagnetic fields (EMF). These standards were upheld in collaboration with EcoNest and monitored by Winch Design’s in-house Sustainable Materials Specialist to ensure compliance with leading global health benchmarks.

The interior embraces earthy tones, organic textures and matte surfaces throughout - keeping mother nature at the heart of the design. The result is a calming, mindful space that encourages slow living and reflects a harmonious relationship with the environment. A key part of the concept was to create an interior that is currently evolving through the use of interesting and unique materials.

One of the yacht’s standout features is the main salon’s educational feature wall, created from crushed eggshells to mimic the look of sand and designed to showcase treasures from travels around the globe. This unique medium has also been used in faux coral wall applications, showcasing how sustainability can be transformed into a versatile form of art. With 250,000 tonnes of eggshell waste produced annually worldwide, this innovative reuse of natural waste creates a sophisticated and organic aesthetic.

The dining area features a table and chairs crafted from 350-year-old felled wood, sourced from timber that had already been harvested. Complementing these are sculptural side tables handcrafted from rush, a species of grass, and created using traditional textile techniques repurposed for contemporary living.

A family-focused classroom and playroom on the main deck showcases a “tree of life,” formed from fallen trees and designed to display treasures collected from family adventures. This space also features a cork marquetry map of the world - a material chosen for its renewability, as cork can be harvested without cutting down the tree it originates from.

In the owner’s suite, natural rope has been woven to form a custom headboard, using traditional weaving techniques. The interiors of the wardrobes are lined with panels containing pressed hay and flowers sourced from alpine meadows, bringing an unmistakably organic quality to the space. These are natural surfaces free from any harmful additives or solvents and by using alpine hay and other natural materials, they help preserve biodiversity and promote traditional agriculture. An infra-red sauna off the owner’s suite is an additional wellbeing tool to facilitate optimal recovery and muscle repair.

One of the most striking features on board is a green living wall made from preserved moss, which forms the focal point of the main staircase, bringing natural beauty and texture to the space. The stairway design is inspired by biomimicry, incorporating a sculptural element made from the root of an elder tree and natural clay plaster walls, a contemporary non-toxic surface crafted using traditional clay plaster techniques.

Wooden walls throughout the yacht are left natural, celebrating the unique grains and knots inherent in each piece. Flooring is supplied by Mafi, an Austrian company known for producing ecological, VOC-free wood floors of the highest quality. The 3D wave pattern across the wood is inspired by walking barefoot across ocean sand and is designed to massage feet as you move around the interior. Carpets are 100% wool, hand-loomed in Sardinia and dyed using natural pigments, adding warmth and texture to the spaces.

Soft, ambient lighting has been carefully chosen to support the body’s natural circadian rhythms. Innovative lighting materials include root-grown light fixtures - an elegant fusion of craft and biology that grows textiles directly from roots - and sericyne silk, a sustainable, non-woven silk ethically spun by silkworms. Together, they bring a refined, organic touch to the lighting design.

Beyond the interiors, the yacht’s engineering also places a strong emphasis on environmental sustainability. Notably it incorporates a selective catalytic reduction system in compliance with IMO emission standards TIER III enabling navigation in marine protected areas and sanctuaries such as the Galapagos.

This remarkable collaboration between Winch Design, Cantiere delle Marche, and a visionary client is redefining conscious luxury, challenging conventional norms and pioneering health-conscious, eco-sensitive contemporary design. Every material onboard has been carefully selected, and analysis undertaken on their specific set of data related to different criteria to identify their impact on health and wellbeing.
