Jetboating
Not particularly suicidal but definitely thrilling, jetboating is a Kiwi invention.“An inboard engine sucks water into a tube in the bottom of the boat and an impeller driven by the engine blows it out of a nozzle at the stern in a high-speed stream. The boat is steered simply by directing the stream.”
I had never heard of jetboating before, but apparently it’s doable in almost every New Zealand river town of any size, most notably Queenstown, where a bracing trip down the Shotover river — the same one you can rappel down and swing across — gets you within inches of jagged rocks. Wear a rubber coat and plastic underpants for this one.
