Invictus will unveil the ST550 Deep Horizon at the Cannes Yachting Festival 2026, introducing a bespoke interpretation of its flagship ST550 developed through Atelier Invictus in collaboration with designer Fabio Rotella.

The project focuses on materials, finishes and the relationship between the yacht’s interior and the sea. Natural woods, tactile surfaces and custom fabrics are paired with a restrained color palette, while bathrooms receive architectural treatments including Silk Georgette in the guest head and Portoro Gold in the master.

Light is a central element of the design, intended to highlight textures and materials while creating continuity between the interior and exterior spaces. Technical fabrics developed specifically for the project extend the aesthetic outdoors, where they feature original patterns.

The st550 measures 55 feet 4 inches in length with a 16-foot-6-inch beam and retains the model’s signature semi-reverse bow. The “S” in ST550 refers to “Space,” reflecting its emphasis on generous volumes and connections between indoor and outdoor areas.

The ST550 Deep Horizon will debut at Cannes alongside Invictus’ TT550, TT460, TT420 and GT320, and will also be exhibited at the Genoa International Boat Show.
