UIM Hydros Head to Boretto for Finale
3-5 October 2025 | River Po, Boretto, Italy
The 63rd Boretto International Motorboat Grand Prix delivers the season finale for three UIM World Championships this weekend, with the F-500 title heading for a thrilling conclusion on the River Po circuit.
Championship Battle
Poland’s Marcin Zieliński holds a three-point advantage over Estonian Erko Aabrams heading into the final round. Italy’s Giuseppe Rossi sits third, perfectly positioned to exploit any mishaps ahead whilst benefiting from home-water knowledge.
Previous rounds:
- Round 1: Żnin, Poland (7 June)
- Round 2: Bad Saarow, Germany (19-20 September)
- Round 3: Boretto, Italy (3-5 October) – SEASON FINALE
Zieliński dominated at Bad Saarow, but the championship remains wide open. Maximum points are available across three heats this weekend, meaning any mechanical failure or racing incident could swing the title.
