Three New Admiral and Tecnomar Concepts - Full Steam Ahead
GetBoat Blog

The Italian Sea Group (TISG) has unveiled three bold new superyacht concepts — the Admiral Explorer 50m Adventure, the Tecnomar 40m Cat 133 FT, and the Tecnomar 46m Evo 155 — all first announced at the Monaco Yacht Show in September 2023 and presented in full detail in January 2024. Each project pushes the boundaries of design, liveability, and sustainable technology, signalling where the superyacht market is heading over the next several years.
Why These Three Concepts Matter
TISG's Centro Stile — the group's in-house design studio — developed all three projects simultaneously, a move that underlines the shipyard's ambition to dominate multiple segments of the market at once. According to Boat International, TISG had 20 yachts under construction at the time of the announcement, giving these concepts a credible production pipeline behind them. Giovanni Costantino, Founder and CEO of The Italian Sea Group, described the trio as giving the group "new stimuli and motivation" heading into 2024, adding that he is confident "the yachting world will continue to reward" the strategies being pursued.
Admiral Explorer 50m Adventure: Expedition Reimagined
The largest of the three projects, the Admiral Adventure, stretches to 50 metres and sits just under the 499 GT threshold — a deliberate choice that keeps operational costs lower for owners while maximising interior volume. Boat International describes the design as "unusual and innovative," and the renderings bear that out.

- Bow master cabin: The owner's suite is positioned forward, with large windows cantilevered onto the hull for panoramic sea views and direct access to a private sundeck — a layout rarely seen on explorer yachts of this size.
- Glass bow segment: A distinctive glazed section in the bow gives the vessel an almost submarine-like visual identity from the waterline.
- Aft deck pod: A pod-style feature on the aft deck sets the Adventure apart from Admiral's current explorer flagship, Planet Nine.
- Glass-bottomed pool: The stern area features a glass-bottomed swimming pool alongside foldable gunwales, maximising the beach club experience.
- Helipad: A touch-and-go helipad sits on the sundeck alongside the wheelhouse and captain's cabin.
The Adventure is designed to deliver the technical performance of a true expedition motor yacht — long range, robust build — without sacrificing the aesthetic refinement that defines the Admiral brand. As Pressmare notes, the forward VIP cabin's cantilevered windows offer "breathtaking views," reinforcing the idea that expedition yachting no longer means compromising on luxury.
Tecnomar Cat 133 FT: The Catamaran Reinvented
The Tecnomar Cat 133 FT is a 40-metre catamaran that draws direct inspiration from TISG's radical existing catamaran, This Is It. Like the Admiral Adventure, it is designed to remain under 499 GT, but its twin-hull architecture allows for an extraordinary amount of usable outdoor space.
- 300+ m² of exterior space: SuperYacht24 reports that the external areas exceed 300 square metres — a remarkable figure for a 40-metre vessel.
- 16-metre swimming platform: By exploiting the two hulls, the internal gunwales, and two folding side doors, the stern opens into a swimming platform approximately 16 metres wide when fully extended.
- 70 m² of solar panels: Integrated across the superstructure arches and hardtop, the solar array reflects a genuine commitment to green propulsion and energy management — not merely a marketing gesture.
- Automotive-inspired detailing: Light lines, large glass surfaces, and teak designs echo the sporty aesthetic of This Is It, with details described as "inspired by the automotive world."
The Cat 133 FT represents one of the most ambitious catamaran concepts to emerge from an Italian shipyard in recent years. Its focus on maximising outdoor living — particularly the 16-metre stern platform — speaks directly to a growing charter and private-owner demand for vessels that blur the line between yacht and floating beach club.
Tecnomar 155 FT: The Evolution of a Classic Line
The Tecnomar Evo 155 is a 46-metre motor yacht born, as TISG explains, from "the need to give continuity to the highly successful Tecnomar-EVO line." Where the Adventure is exploratory and the Cat 133 FT is visionary, the Evo 155 is the most immediately accessible of the three — a refined evolution of a proven formula.
Exterior and Deck Layout
The exteriors are described as "strongly sporty" with the sinuous, captivating lines that have become the Tecnomar brand signature. Key deck features include:
- A large stern window on the beach club level, flanked by two folding doors that open directly to the sea, creating what TISG calls "360-degree liveability between interior and exterior."
- A sundeck bar and sunbathing area with an aft swimming pool.
- A second pool and sunbathing area at the extreme bow of the upper deck, convertible into a dining area with 180-degree ocean views.
Interior Accommodation
The Evo 155 accommodates guests across five cabins arranged across three decks:
- Two guest cabins on the lower deck
- Two VIP cabins on the main deck
- The owner's cabin on the main deck
Two full-beam salons on the main deck ensure generous communal living space — a layout that works equally well for private ownership and charter operation. The Evo 155 sits under 499 GT, keeping it commercially attractive for both segments.
Common Threads: What These Concepts Tell Us About Superyacht Trends
Taken together, the three concepts reveal several clear directions in contemporary superyacht design:
- Sub-499 GT engineering: All three projects are designed to remain under the 499 GT threshold, reducing crew requirements and operational costs without sacrificing size or amenity.
- Indoor-outdoor fluidity: Folding doors, retractable gunwales, and convertible deck spaces appear across all three designs, reflecting the industry-wide shift toward seamless transitions between interior and exterior living.
- Sustainable integration: The Cat 133 FT's 70 m² solar array is the most explicit nod to green technology, but the broader design philosophy — maximising space efficiency, reducing operational complexity — aligns with sustainability goals across the fleet.
- Dual-use versatility: Each concept is designed to function effectively as both a private yacht and a charter vessel, reflecting the commercial reality that many new builds enter the charter market to offset ownership costs.
Frequently Asked Questions
When were these concepts first announced?
All three projects were first announced at the Monaco Yacht Show in September 2023 and presented in full detail, with renderings, in January 2024.
Why are all three designs kept under 499 GT?
Remaining below 499 gross tonnes allows owners to operate the yachts with a smaller certified crew and reduces certain regulatory requirements, lowering ongoing operational costs significantly — a major consideration for both private owners and charter operators.
What makes the Tecnomar Cat 133 FT different from other catamarans?
Its 16-metre-wide stern swimming platform — created by combining the two hulls, internal gunwales, and folding side doors — and its 70 m² integrated solar array set it apart. The exterior design also draws directly from the radical aesthetic of TISG's existing catamaran This Is It, giving it a highly distinctive visual identity.
Can these yachts be chartered?
While the yachts are concept projects at the time of writing, TISG's existing fleet — built under both the Admiral and Tecnomar brands — includes vessels available for charter. The layouts and specifications of all three new concepts are well suited to charter operation, particularly the Evo 155 with its five-cabin layout and dual full-beam salons.
