The GTT 115 was designed to travel farther than its sleek profile might suggest. When Dynamiq and Studio F. A. Porsche unveiled it at the Monaco Yacht Show in 2017, they gave the 35-metre hybrid superyacht a stated range of 3,400 nautical miles and a top speed of more than 21 knots. Those are the makers’ figures from the launch, not results from an independent test. [1]
Gran Turismo across the Atlantic
The name stands for Gran Turismo Transatlantic. Studio F. A. Porsche wanted to create a coherent design for a yacht that could both move quickly and cover great distances. Rather than letting each individual customer define the entire look from scratch, the vessel was given a distinct form from the outset. [1]
Porsche Newsroom described a hybrid system with three variable-speed generators, a metallic silver finish and a plan for no more than seven examples. The planned limit says something about the ambition, but we do not have documentation here for how many were actually built. [1]
The interesting point is the span between categories. It is far larger than the private sports boats carmakers are often associated with, yet it is still conceived as a Grand Turismo: a vehicle where the journey and the form matter just as much as the destination. [1]
More than a superstructure
Studio F. A. Porsche was asked to do more than draw an attractive superstructure. According to Porsche Newsroom, the idea was a coherent design for a yacht able to cross the Atlantic while still feeling fast and manoeuvrable. At 35 metres, it offers substantial space aboard but is smaller than many yachts associated with ocean crossings. That is why the stated range of 3,400 nautical miles matters more to the story than an impressive top speed alone. [1]
The silver metallic finish and taut lines carry a clear connection to Porsche's design world. Beneath them, the maker described a hybrid system with three variable-speed generators. It was the project's technical response to the desire for both speed and range. Porsche and Dynamiq spoke of no more than seven examples at launch; that was a production plan, not proof that seven boats were completed.
