Like Steve, same spot but a week later... same situation in that I got on to a big 8ft bombies and outsurfed my kite. Kite backstalled, not enough wind (and on too onshore) to correct it and all I could do is keep surfing the wave until most of its energy dissipated. Kite hits the water behind the wave, I punch out, hit the water, board gone (no leash). Next wave pounds my kite (it's shredded - total loss). I was still attached to my safety so pull the bar back towards me and used what was left of the kite to wash me to shore. Took a few on the head but without a floatation jacket so I managed to dive under a few of them.
I have been thinking about the "what if" scenarios for a while - well before this incident. How to rescue an unconscious kiter, how to drag someone in from the back when the big bombies are breaking, how to engage life guards in kitemares, etc. In fact, I sent messages to all the strapless kiters on the Northern beaches with info on a custom rescue course led by one of the guys that trains the professional lifeguards. Lots of interest so think it's time we set it in motion.
Also, in the last 2 weeks half a dozen of the more experienced big wave kiters decided to buy helmets - for those days when you do decide to use a board leash.
Lastly; I've been eyeing up an inflatable life vest that's small and snug enough to wear without getting in the way of the harness. Wear a rashie over it. For when it all goes to **** (as in Steve's case).
