The 2016 UIM F1 H2O World Championship was the 33rd season of Formula 1 Powerboat racing. The season consisted of seven races, beginning in Dubai, UAE on 4 March 2016, and ending in Sharjah, UAE on 16 December 2016, although initial plans indicated a ten race calendar.
Philippe Chiappe, driving for the CTIC F1 Shenzen China Team, entered the season as defending double world champion and successfully retained his title to become only the third driver in the sport's history to win three back-to-back drivers' championships. In addition, Chiappe's CTIC F1 Shenzen China Team clinched their first teams' championship. Both the BRM Pole Position Trophy and Fast Lap Trophy were also won by Chiappe.
There was a considerable amount of continuity from 2015 into the 2016 season as far as team and driver line-ups were concerned. Following the upheaval the previous year, the driver pairings at CTIC China, Victory Team, Team Abu Dhabi, Mad-Croc and Team Sweden were all unchanged. At the F1 Atlantic Team, Youssef Al Rubayan had retired, and was replaced by former Team EMIC driver Christophe Larigot to partner regular driver Duarte Benavente. To replace Larigot, Team EMIC hired promising rookie Mike Szymura. The German was already a three-time F4-S champion and would drive a Jonathan Jones-built Dragon boat from the second round onwards. Francesco Cantando's team retained himself and Bartek Marszalek as drivers, but lost their Motorglass sponsorship, thus reverting their name to Blaze Performance Team in deference to Cantando's self-built Blaze boats. Bernd Enzenhofer did not return for the team. At Emirates Racing, Ivan Brigada stood in for Ahmed Al Hameli at the opening round in Dubai, though Al Hameli returned for France, partnering Erik Stark for the rest of the year. Brigada meanwhile made a further appearance, this time for Team EMIC at Évian-les-Bains in a third boat. Cédric Deguisne's Maverick Racing team participated in the European rounds of the championship for a second year, while there were additional entries at the final two rounds. Grant Trask brought the Trask name back to Formula 1 powerboats when he drove a third boat for Team EMIC at both Abu Dhabi and Sharjah, while Rashed Al Qamzi, cousin to Thani Al Qamzi, was rewarded for winning the F4-S title with a one-off drive in Sharjah in a third boat for Team Abu Dhabi. Away from driver changes, another legend of the sport made a return to team activities as Renato Molinari joined the Emirates Team as Team Principal alongside Scott Gillman.
