The 164-foot No Stress Two is Rossinavi’s first hybrid yacht monitored by artificial intelligence. The first of the yard’s Blue series, the 164-footer was launched in April but delivered it to the owner last week. The custom builder is touting its AI integration as it moves forward with even more sustainable hybrid vessels.
“Artificial intelligence allows you to enjoy the electric experience on board to the fullest,” said Federico Rossi, the company’s chief operating officer, noting No Stress Two will have five operational modes from full diesel power to full electric.
The yacht has a sleek, modern, and almost futuristic look. It’s what the lead designer Enrico Gobbi calls an “automotive aesthetic,” with a silver hue and long black window that runs nearly three quarters of the hull length amidships.

The superstructure and upper deck notable by their curves, with a swept-back radar arch and large radomes on the top. On the front of the yacht is a large Jacuzzi. “The owner chose dynamic lines for this sporty superyacht,” says Gobbi, who oversaw the project with his Team For Design. “I wanted the boat to be in motion even when it is at anchor, combining long curves always in tension, and streamlined bridges that recall the wings of a jet.”
The transom also retains the sleek look at speed but folds down into a beach club. The area, with its nearly 30-foot-wide beam, is defined by open space as well as stairs that head up to the main deck. The interior is described as “minimalist” and built with “quality materials” but is short on details or images, so must be left to the imagination.

The fast-displacement hull is designed around the hybrid system, with two electric motors and diesel propulsion, though Rossinavi declined to specify the sizes.
Its five modes range from full diesel for speed to full electric for cruising in relative silence. There is also one to power the yacht’s hotel mode.

Rossinavi’s website describes its AI as having multiple functions, including monitoring the battery pack to keep it charged between 20 and 80 percent at the optimum charge level. But it also takes the AI language a step farther by dialoguing with crew “in permissible ways” to keep the environmental impact as low as possible with the crew implementing operational changes across the boat.
“This is only the beginning, as this technology will be optimized next year, revealing its fullest expression with the launch of the Sea Cat,” Rossi says. The 141-foot catamaran should be able to cruise on electric-only mode for an entire day, he explains. Plus, the initial renderings very cool and sleek compared to most of the superyacht catamarans on the water. With the hybrid system, it should be the cat’s meow for the Italian builder.
