In the clip, the vessel can be seen travelling at speed through the choppy water, throwing the woman around as she grips the side of the boat to steady herself.

But as the boat continues, the woman suddenly disappears from view, with no indication whatsoever as to where she went.

Many people were left gobsmacked by the video after it went viral , with one viewer leaving the comment: “That was like a magic trick.”
