You may have seen this but I just came across it and thought it worth sharing.
Infact how I came to see it was through a link on an article in SA this week, involving Tyrone (who is the featured legend in this vid) who had a very close call with a big white earlier this week!!
Google duct tape surfer for other awesome footage.

Here is the link to the close call article too.
