Energy Class tests prototypes consistency

The day’s headline event, the Endurance Race, presented Energy Class competitors with a challenge that tested their prototypes on every level. For nearly three hours, teams had to complete lap after lap of the course while striking the best balance between performance, energy consumption and mechanical reliability.

 

At the end of the race after completing 79 laps, Elettra UniGe Team (Italy) won ahead of Physis-Polimi Energy Boat (Italy) in second, while the University of Bologna Argonauts Team completed the podium with 76 corrected laps. 

Artificial intelligence confirms its potential

Technological approaches reflect this evolution with more focus on eco-design, hydrogen-electric hybridization and smart energy management. Solutions are being designed not just for performance but also their industry application potential.

 

Of the prototypes registered:

  • 33 feature battery-electric systems
  • 9 incorporate hydrogen technologies
  • 1 uses methanol
  • 9 are employing foils

Their choices reflect a shared goal to reconcile performance, energy efficiency and a reduced environmental impact.

A race adapted to weather conditions

In the SeaLab Class, sea conditions prompted the Race Committee to adapt the format. Originally scheduled to cover 16 nautical miles, the race was shortened to 5 nautical miles. Red Wave (Italy) won with a time of 25 minutes 15 seconds, ahead of the TU Delft Hydro Motion Team (Netherlands), which crossed the finish line after 43 minutes 7 seconds. The main aim was to assess solutions developed by the teams in real-world conditions, prioritising system reliability and sustained performance, not just the top speed.

Boats in the Open Sea Xperience category also competed on the same course, with XNRG topping the ranking. 

A decisive final day ahead

In the Energy Class, the Elettra Unige Team is setting the pace, while Red Wave holds the provisional lead in the Sea Lab Class, as does the Adria Autonomous Boat Team (Croatia) in the AI Class.

 

The competition continues on Saturday with the slalom and Championship Race for the Energy Class boats, and the AI Slalom and an endurance race for the Sea Lab class.
