Great to see this. That's pretty full-on. Big
for pushing the limits.
I'm not surprised the surfers hate this! I would too! I'd stay out of their way.
Most of the video it looks like you're riding upwind when you're heading left.
It also looks like you're riding highly powered. Out of interest what's the wind strength and kite size? Looks like about a 7 in 30+ knots.
There are a few short clips of you heading downwind to the right - e.g. around 2:06 and 3:21 on the video.
That's kind of more interesting to me, even though you're not riding in the critical section, as there you're riding under wave power only or mainly at least.
To me riding the wave upwind under kite power doesn't have quite the same appeal, though of course it must be a real rush to be in waves that size.
What I'd really like to see is someone riding to the right, slowing it down a little, manoeuvring under little to no kite power.
Something like a Gofoil works well for that riding style in lighter conditions, but the thick wings would probably be too slow for waves of that speed and power, and probably necessary either. Maybe something in between?
In terms of where the limits are:
What size wave can be ridden with a kite foil?
In what wind conditions is it viable? - the bigger and faster the waves the more windy it needs to be for the kite to be able to keep up, and like you say, angle is important.
And I'm really interested in knowing where the limits are where the kite is being used as just the tow - i.e. big wave foil surfing towing in with a kite.
Optimal equipment? Both foil size and characteristics, mast length, kite size etc.
All this is still up for grabs if you ask me, well done for taking on the challenge.
The Armstrong foils look really interesting.
