I already have and more than a day, try four days with as thick a school as you see in the images. This was four years ago, before GoPros. A much larger school really because it was there pretty much uninterrupted moving north for the entire time day after day for at least four days of wind. You would see shadows moving all around you for the entire session each day. All the sharks and there were hundreds or thousands over all that time, I noticed seemed to ignore me except around sunset. At sunset over two days, several dorsals would show up on the surface and home in on you. Not sure what was going on beneath the surface. I would move inside the break or call it a day. I wasn't attacked, nor were any of the other kiters either, that time.
Looking at a recent video shot around the time Steve Schafer was killed, though further south in Palm Beach Country, I see sometimes sharks ignore us and other times they chase us. I don't recall seeing the chasing during the 2007 migration described above, they mainly seemed to ignore us. This matches some comments from the Pacific from pilots observing larger shark behavior moving with and chasing kiters way back in 2002 that I just tripped over again. If you wipeout during one of these tracking events, what are the odds against a hit and run attack? Not real good I would think. This is far different from routine riding outside of shark concentrations. Normally shark sightings are fairly rare in this area outside of the migration.
I have already said, I have given up kiting among large groups of sharks. Been there, done that, learned some new information and don't plan to do it again. Diving** is a different matter, under certain conditions.
Despite all this, there are very few shark attacks on kiters (unlike surfers) and lots of wind related incidents, accidents and fatalities. I've never been put in the hospital by a shark but have been treated twice for wind related injuries and easily could have been taken out a third time way back in 2000 in a squall gust that dragged me about 150 ft. at high speed with a two line 5 m Wipika Classic?! There have been many others worldwide since this sport started. Sharks and excessive wind can hurt or kill you, it just happens much more often with wind in our sport.
Another way to spend time with sharks where you aren't oblivious of what is going on beneath the surface.**
