One of the most thrilling experiences of my life was when I went on a jet boat ride many years ago.
It was wild, fun, exhilarating and at times downright scary. I am not a person who scares easily, but there were a few moments here and there where I seriously wondered what I was doing.
The very skilled and trained driver did some manoeuvres that made me prepare myself for the worst.
But that is the point of something like a jet boat ride - it is an adventure sport and there is an element of risk.
Jet boats are in the news at the moment after five people were injured when a Shotover Jet boat hit a rock in a narrow twisty canyon on the Shotover River on Saturday.
