An interior design combining minimalism and user-friendliness
The interior design of the Sunreef Ultima 111 strikes a balance between sophistication and simplicity. The palette of earth tones and natural materials creates a warm ambience, ideal for long crossings. This aesthetic harmony reflects Phathom's attention to detail, combining boldness and serenity in both common and private spaces.
The integration of âeuros biophilic design principles such as organic curves and âeuros purified furniture promotes a soothing connection between man and sea. The result is a fluid, restful interior designed to appeal to sailing enthusiasts in search of comfort and modernity.
Optimized space for life on board
Designed to accommodate up to ten guests in five spacious cabins, the Ultima 111 offers an innovative approach to interior layout. The cabins are located above the hulls, a rare choice that maximizes natural light and offers unrivalled panoramic views.

The main living room illustrates this quest for openness with retractable balconies. These extensions transform the space into a veritable open-air terrace, ideal for dinners at sea. What's more, the owner's cabin features a private terrace with direct access to the foredeck, adding a touch of exclusivity.

Thoughtful use of materials
In an industry where expectations of sustainability are growing, Sunreef highlights materials carefully selected for their quality and low environmental impact. Natural woods, eco-friendly textiles and minimalist finishes create interiors that are both sustainable and aesthetically pleasing.

This choice underscores our desire to align luxury with responsible practices, and is a further argument in favor of owners concerned about the impact of their yachting.
Light and connection with the environment
The catamaran features large glass surfaces and high ceilings, allowing total immersion in the seascape. These technical features, rare on catamarans of this size, reinforce the feeling of proximity to the water, while offering bright, pleasant spaces.

The open-concept layout and bay windows also enhance the impression of space, a challenge often encountered on multihull units. This architectural mastery is a real asset for comfortable cruising, even over long periods.
Innovation-driven construction
At 36.25 meters in length, the Sunreef Ultima 111 illustrates the technical know-how of its shipyard. Although no details of the propulsion system are mentioned, we can expect hybrid or electric options, in line with Sunreef's eco-responsible strategy.

The multihull hull provides greater stability and optimized performance, ideal for those looking for comfortable crossings without compromising safety.
Towards an evolution in nautical design
The Sunreef Ultima 111 paves the way for a new generation of catamarans, where design is no longer just visually appealing, but becomes a lever for comfort, durability and experience at sea. This model should inspire other builders to incorporate responsible practices and avant-garde fittings into their future projects.
For wealthy yachting enthusiasts, this is a model of refinement and respect for the marine environment.
