The action was nothing short of spectacular as the fleet of foiling GC32 catamarans flew round Muscat's stadium racecourse off Almouj Golf in gusts up to 25 knots.
The final race also saw 2016 Extreme Sailing Series champions Alinghi snatch second place overall from Oman Air right on the finish line.
Alinghi needed to beat Oman Air with a boat in between them to leapfrog them on the scoreboard and they did just that, as Tawera Racing from the Royal New Zealand Yacht Squadron overtook Oman Air, helmed by Kiwi Phil Robertson, at the last minute.
"We were in some strong positions today and just managed to slip in the last race which is a bit of a shame, but that's yacht racing and it's what we've got to get better at," Robertson said.
Austrian crew Red Bull Sailing Team, who had Kiwis Stewart Dodson and Will Tiller on board, had to settle for fourth place ahead of Team Tilt and Team ENGIE in fifth and sixth respectively.
Chris Steele's Tawera Racing, who join the Extreme Sailing Series this season, finished seventh, with Land Rover BAR Academy in eighth and NZL Sailing Team in ninth.
The four days of thrilling racing were the perfect start to the 11th year of the Extreme Sailing Series that sees eight Acts held in three continents culminating in a season finale in Los Cabos, Mexico, in December. The Extreme Sailing Series excitement will resume with Act 2 in Qingdao, China, from April 28 to May 1.
The NZL Sailing Team return to New Zealand before heading to Bermuda for a training block on the AC45s they will race at the Red Bul Youth America's Cup.
