new test today of the Hysper2 4m, very "viril" ...
Wind was turbulent and irregular ... from 6 knots in some lulls, up to 39 knots measured in highest gusts ... Swell was big and irregular, up to approx 2.5 and 3 meters, with smaller waves superposed at 90 degrees; I was sometimes impressed to have to "climb" such water "walls" ...
But it was "feasible" with this kite ;not very comfortable I must admit, but not in danger, never. I had to fight to keep balance sometimes even with my 1200 cm2 hydrofoil but I only fell twice in the water. I got one fronstall collapse of the Hyper but it recovered its shape in the middle of the window and did not touched the water.
A friend , good foiler, has put his Gong LEI single Strut in the water several times in main lulls ; Otherwise he was managing the wind as well.
In the end I feel into the "wash machine" of the shore break, because in Nice the shore break is so close to the beach (2-3 meters) that you are literally lifted up then the back reflux suck your feet backward into the next wave to come ... I made several rolls under water, shocking the round stones and with the foil at less than 1 meter from me ... but no hurt and no material damage despite the 3 successive washing in those 2-3 m waves ...
