This looks like it has a lot of potential. If you had a foil that self-regulates its depth then you have the resistance of the line to the foil through the water. The rest is the air resistance of your body as you can be above the water with a line from your harness to the foil. No board needed. You just fly the kite as normal.

Its obviously going to be dangerous to have a foil flying around if it comes out of the water so you have to get it working and then keep away from everyone else, but it should be able to run fast in bad chop.

Finally --- someone with enough for-site & creativeness to realize there
just Might be another way !!!!!!

So what do Ya see as a correlation between the target wind-speed , &
and the solution that sail-rocked came up with ????

I see a LOT !!

I think it does show that it can be done, but you need an ultra-reliable system for keeping the foil under the water. You can see in his video that it plops out at one stage.

He is using air/water pressure to control a vane at the tail of the foil.

The resistance of the line through the water might get quite high and affect the control of the foil at higher speeds, so it might be replaced with an aerofoil for streamlining.

Like I said it looks like it could get dangerous so the development would need to be rigorously thought through, but it does seem to have potential for high efficiency and speed.

Here's the Sea Glider, but the foil doesn't seem to stay under the surface well enough.

Now that looks fun and I love the first clip with the pilotless kite as it is thinking outside the box but I do think there is more potential for disaster than tethered flight with that second clip. The thing you need with speed is razor sharp control and reaction and it shown neither, not criticizing the principal of it, there could be something in it. I'm not convinced there will be boards as we know them going much faster than they do now, it will have to be something different to a board I reckon.
