At more than 270 kilometres per hour on water, a rogue wave can cause carnage for hydroplane and formula one tunnel drivers.
Grand Prix hydroplane racer Raymond Hart knows that well, having had a spectacular crash in his boat, The Boss, at Cromwell last month.
Despite the stunning crash, where he spent six minutes waiting to be rescued in his safety cell, Hart and his rebuilt boat will hit the water this weekend at Lake Karapiro.
New Zealand Powerboat Federation president Denise Moughan said the event will provide great viewing, with boats travelling at incredible speed hugging the banks of Lake Karapiro on a two kilometre course.
The power and sound of the boats will literally shake the banks of the lake, she said, giving spectators a sense of the raw power the boats hold.
"These skilled drivers are on edge and they do make mistakes as did Grand Prix hydroplane driver Raymond Hart recently," she said.
The highlight of the event will be the six 2500 horse power hydroplanes competing, while Formula One tunnel boats will also reach speeds of 230kph.
Racing starts at 8am tomorrow, with water ski racing until 10am and then circuit racing.
Grand Prix hydroplanes will have three testing sessions before they finish the day with the flying lap competition, to find poll positions for Sunday's racing..
Admission is $15 for adults, while children under 12 are free.
