2015 F1 Powerboat World Championship

Philippe Chiappe, driving for the CTIC China Team, entered the season as defending world champion having won his first title, and the first for a Frenchman, the previous year.

[1] Chiappe successfully defended his title, securing enough points at the penultimate round in Abu Dhabi and thus became the series' fourth back-to-back championship winner.

[2] In addition, the championship witnessed its first ever female race winner, when Marit Strømøy won the final round at Sharjah, with the occasion attracting international media coverage.

[17] At the third race of the year in Porto, Torrente was joined by reigning Class 1 and X-Cat champion Nadir Bin Hendi, making his debut in the series.

The outcome resulted in Al Qamzi being sacked from the team, and at the eleventh hour was replaced by Italian rookie David Del Pin.

[9][22] After the second round in France however, Del Pin was demoted to reserve driver and Al Qamzi returned to Team Abu Dhabi in time for the third race in Portugal.

This left Brigada and Slovakia's Tomáš Čermák without drives and ensured that the field returned to being entirely powered by 2.5 litre two stroke Mercury engines.

Qatar returned to a single slot having filled in for the cancelled Ukraine round in 2014 with an additional race, whilst the traditional end-of-year double header in the UAE continued at Abu Dhabi and Sharjah.
