Going 100km in about 90 minutes isn't travelling that fast - but what about when it's on the water?
Northlanders will get to experience the thrill of high-speed ocean racing this weekend when the Thundercats return to Waipu after a 100km race from Takapuna to Waipu on Saturday.
The Thundercat Racing Association is holding a 100km endurance race for the powerful crafts, starting at Takapuna Beach about 11am. About 90 minutes later the winner will cross the finish line just off Waipu, after a high-speed journey up the coast.
Thundercat racing is a high-adrenalin, high-action sport with explosive wave jumping and tight competitive surf racing in a tunnel-hulled inflatable boat. The crews consists of a driver steering the boat and a co-pilot who uses his weight to stabilise the craft and obtain optimum speed.
Thundercats have taken New Zealand by storm, entertaining thousands of spectators at some of the most popular beaches around the country such as Whangamata, Waihi, Waipu, Papamoa, Pauanui, Orewa, Takapuna Beach, Piha and Mount Maunganui.
