For those not familiar with the jargon of kayak dangers and obstacles, a sieve is when water is forced through an opening in a rock. Water can flow freely through it, but with something like a kayak or a person, this is not always the case. Jordie Searle found himself on the wrong side of a sieve while paddling the Nevis River for Red Bull's Flow Hunters.

It is haunting to see the footage of a man literally fighting for his life. You can see Jordie becoming more tired as the water forces him under. Rush Sturges, one of the world's best paddlers, only makes the gravity of the situation more dire as he describes how he thought he just saw one of his friends die. Luckily, Searle is flushed through the sieve and makes his way safely to shore. It is videos like this that keep paddlers awake at night.
