New Flagship: Invictus ST550
Tradition Meets Innovation
The new 55’4” Christian Grande-designed Invictus ST550 preserves the defining features that distinguish the Invictus brand such as the iconic semi-reversed bow and also includes plenty of innovations.
The company says the design was inspired by the timeless allure of classic tenders, but adopts softer, rounded forms, giving rise to the modern silhouette.
Paying homage to classic tenders, it integrates stylistic elements such as the antenna housing—enhanced with a carbon fiber detail that evokes the aesthetic of a funnel—and offers the option to choose a glossy mahogany finish instead of teak on wood furnishings and accents.
The ST550's extensive use of smoked glass provides transparent views of the sea, both above deck and below. Its high bulwarks offer protection and safe passage fore and aft without compromising the sleek profile. The stainless-steel "calandra" (an Italian lark) at the bow, housing the illuminated logo, is an iconic feature of the brand.
Innovation and Comfort
One of the innovations in the new model is the expansive bow lounging/entertaining area consisting of a large U-shaped sofa and a spacious sunbathing area that converts to a large lounge. The combination of high bulwarks and protective glazing allows for visual contact with the sea, offering a view of the navigation while offering privacy when docked.
"In opposition to the more common approaches, which tend to sacrifice space on the main deck and bow to prioritize the stern," says General Manager Rosario Alcaro, "we have divided the spaces to enhance all three areas without sacrificing any one in favor of the others. . . . In particular, we have enhanced the bow layout, offering a more private experience there rather than in the interior spaces or the traditionally more active stern."
The cockpit features a generous living area, which can be equipped with all the necessary comforts (fridge, sink, grill), as well as a dining area that can be converted into a sunbed over 6.5’ (2 M) in length and depth. The large sofa is a freestanding piece that further expands the perception of space.
Collapsible bulwarks significantly expand the walkable area, eliminating visual barriers and enhancing the sense of connection with the sea. At the stern, the flush gangway makes boarding easier, and the large swim platform can be lowered below the waterline to facilitate tender launching.
The ST550 also features a garage for a 9.2’ (2.8 M) jet tender, a rarity in this segment.
The garage features a two-level opening: a full opening for tender launching and a partial opening that allows access without disturbing the sunbathing area.
A retractable awning, hidden within the superstructure, provides shade during the hottest hours, while a second carbon fiber awning at the bow offers additional protection.
Power is dual Volvo-Penta IPS800 or IPS950 engines, assuring easy handling in the harbor.
Interior Design and Functionality
On the main deck, large, electrically-operated side windows and a glass door at the stern offer almost uninterrupted views of the surroundings, providing a seamless connection to the cockpit.
The right-side lateral door further enhances functionality, offering easy access to the walkway during maneuvers without needing to pass through the cockpit. Natural ventilation is integrated via a front flap that captures air while cruising.
Additionally, the ST550 is equipped with a powerful air conditioning system for maximum comfort.
Accommodations for Four—or Six—Below
Below deck, Christian Grande has designed two luxurious cabins—Master and VIP—each with its own bathroom. The master bathroom is full beam at the bow, while the second serves both as a day toilet and an ensuite for the second cabin.
Midship, a spacious living area can be converted into a third cabin and kitchen, with the main deck kitchen "disappearing" to further open up the salon.
Invictus Atelier: A Bespoke Experience
The Invictus “Atelier” program offers a wide range of customization options in colors, materials and configurations. This allows for significant freedom of choice, enabling the client to configure the boat according to their tastes and needs.
Additionally, clients are taken through a true virtual workshop, where they can design the boat with custom materials and dedicated features. The standard boat thus becomes a tailor-made creation that expresses the personality, style, and preferences of the owner, per the company.
Christian Grande says that the choices are nearly unlimited for customization.
“We’ve focused on redesigning the outdoor upholstery, moving away from the usual materials found in this segment, such as vinyl, and opting for high-quality breathable fabrics typically used on large yachts, accented with synthetic leather trims, as is typical for Invictus. And if the owner desires something even more unique, they can take advantage of the Invictus Atelier program.”
World Debut at the Cannes Yachting Festival 2025
The ST550 will make its official debut at the Cannes Yachting Festival 2025 alongside the Invictus TT550, marking a significant milestone for Cantieri Aschenez Yards.
