Super-charged hydroplanes will provide some fast-paced action on Lake Dunstan this weekend.
The lake will provide the backdrop to the final of the four-round Grand Prix Hydroplane races, which feature nine of the machines, best known for their speed.
Powered by V8 engines, the hydroplanes will reach speeds up to 280kmh.
skills over recent months as part of the 2019-20 Hydro Thunder Series, which had already been to Lake Taupo, Lake Karapiro and Lake Rotoiti.
Lake Dunstan Boat Club committee member and event convener Vic Haggerty said racing had traditionally been on the Kawarau arm, but silting had put a stop to that.
However, there was a plus side to racing in the main body of the lake, he said.
“We can lay out a course with 750 metre front and back straights where Grand Prix Hydroplane pilots enclosed in their spacecraft-style safety cabins can hit close to maximum speeds flying over the water on a cushion of air.”
Mr Haggerty plans to pilot the hydroplane Miss Aberdeen, if a vital engine part arrives on time.
He apologised in advance for the noise created by the roaring machines, but hoped people would be understanding and appreciate the event was for one weekend only.
Practice and racing events will take place from 9am to 4.30pm on both Saturday and Sunday.
“Over this time there’s lots of relative quiet as other classes compete between the Grand Prix races that take only four or five minutes.”
Among the other classes to race are V8 powered flat bottom “flatties”, Formula 1 and 3 tunnel hulls and outboard powered monohulls.
And, where class numbers are small, there will be mixed class racing.
Races will start and finish opposite Lake Dunstan Boat Club, at McNulty inlet.
