The Concept
The Seataci is yacht concept that uses a biomimetic propulsion system resembling the movement of whale’s tail. Its main hull would be lowered underwater, providing passengers with an excellent underwater view of the coral reefs and marine life. It features a dozen villas and two landing pads specially designed for personal flying drones.
Origin of the idea
The idea for the Seataci first came to me while my wife and I were visiting the St. Regis resort in Bora-Bora. We were scuba diving one of the channels, and I started thinking about a new type of cruise ship concept capable of navigating in shallow waters by using an eco-friendly propulsion system. First I had in mind a commercial type of vessel, but it could probably first be developed as an experimental / scientific yacht that would bring together scientists and their benefactors.
How it works
The Seataci would be capable of submerging itself by using a water ballast system to sink its main hull. Two side pods would be used to stabilise the ship, and they would be linked with a hydraulic system that would also double as a dynamic suspension. The ship’s crew and passengers would be able to travel to those pods at any time during the cruise, and passengers could use them as galleries to get a different viewpoint from the ship.
The ship’s engines would be housed in each pod. A biomimetic propulsion system similar to the Iruka concept would be designed to propel the Seataci. This system is basically an oscillating foil that pushes the water like the tail of a whale. It might prove more efficient than propellers, would probably generate less noise under water, and it would allow the ship to sail in shallower waters without breaking its propellers or rudders.
Each pods would feature enclosed water propeller that would siphon water from side intake grills and push it forward when the vehicle needs to back up, like reverse bow thrusters. Another option would be to integrate a pivot around the pods vertical axis to reverse the ship’s course.
As you can see, the boat’s actual hull occupies a lot of volume, so it will be hard to sink.
This is our first iteration, only meant to depict the idea. Future version of the Seataci should take into account weight, volume of water displaced, type of material, ballasts size etc. They would look different, but would propose the same features.
The lower tail section of the main hull would feature an impressive under water experience for the passengers, with large panoramic windows located on each side of the ship. Some of the ship’s suite could be located in that lower section for the view and for the minimal roll. A dining hall or an observatory lounge could also be installed there. On the main deck, a tropical garden would surround a pool next to landing pads for personal drone. The drones could be used by customers to fly to the shore or visit small ‘motu’ or ‘atolls’ nearby.
What It’s Used For
The Seataci is first and foremost a luxury yacht, but it could also be built and sold as a small scientific or commercial excursion ship. It would be interesting to use it to explore channels or islands located in shallow waters and witness the fascinating underwater life during each cruise. When personal drones become widely available and safe, the Seataci could serve as a landing platform to explore inhabited islands without using boats.
Integrating new technologies like the oscillating foil is probably a big risk; however it could provide a good payoff if this technology proves to be more sustainable than what is currently being used.
The Designer
I would like to thank Martin Rico, who created the images of the Seataci concept. Martin lives near Buenos Aires, Argentina. He studied Design at the University of Buenos Aires and now works as a Freelance Industrial Designer. Martin also created the images of the Mercuri personal jet and the Sandofi urban cart for the homeless.
Azimut has unveiled its new 38.2-meter Grande Trideck superyacht, marking a design evolution for the Italian builder's flagship series. The vessel features interiors by Milan-based studio m2atelier, implementing their "Barefoot Luxury" concept focused on informal sophistication.The exterior design by Alberto Mancini retains Azimut's characteristic sleek profile while incorporating new elements like a recessed foredeck pool with integrated chaise lounge. The interior architecture emphasizes clean geometries, with straight horizontal and vertical lines creating an expanded sense of space. Diagonal elements appear selectively to establish intimate areas within the open layout.Notable interior features include a signature "Unveiling Wall" in the main salon - a motorized panel of vertical wood slats that slides open to reveal a hidden television. Floor-to-ceiling glazing throughout guest areas maintains visual connections to the seascape. The owner's suite utilizes layered glass partitions to preserve sightlines while ensuring privacy.Custom furniture pieces designed by m2atelier and manufactured by Giorgetti follow the Integral Design approach, ensuring stylistic continuity throughout all interior elements. The Sky Lounge incorporates a convertible hi-lo table that transforms the space between lounge, dining area and media room configurations."Light becomes the invisible thread that connects every environment," explained m2atelier founders Marijana Radovic and Marco Bonelli. The lighting design uses concealed LED strips and strategic window placement to accentuate material textures and spatial volumes.The Grande Trideck represents the first of three new models in Azimut's redesigned Grande series, with two additional yachts scheduled for debut at the September 2025 Cannes Yachting Festival. Technical specifications including propulsion systems and performance data remain undisclosed at this stage.Azimut's Product Design Director Federico Lantero described the project as creating "an atmosphere that evolves with those who experience it" rather than focusing on traditional displays of luxury. The design separates crew circulation routes while maintaining visual openness in all guest areas.Azimut Yachts is an Azimut Benetti Group brand. With its Atlantis, Magellano Flybridge, S, Verve and Grande collections, Azimut offers the widest range of 10 to 40 meters.Credits: Azimut Yachts

Crew quarters forward contain two bunk beds and a separate bathroom. Interior design emphasizes spatial perception through mirrored surfaces and LED lighting strips by Altraluce.The 16-square-meter sportbridge divides into three functional areas: a sunbathing space aft, central dining section with L-shaped sofa and extendable table, and forward helm station. The area can be shaded by either a standard awning or an optional carbon fiber bimini top.Notable features include a main deck galley with retractable glass panel connecting to the cockpit, and a helm station with pillarless windscreen for 360-degree visibility. The bow area can be configured with either sun pads or a dinette featuring a convertible table.Construction utilized Pershing's plug and mould technology, with the hull and superstructure built at the Mondolfo facility dedicated to GTX series production.
