This is a very good question. Water relaunching an inflatable should
need more explanation.

After an inflatable is flipped over on its back, there are 3 phases to a
successful relaunch: the catch-the-wind phase, the
sliding-to-the-window-edge phase and the launching phase.

The catch-the-wind phase is the least understood. Once an inflatable is
on its back, somehow a tip/part of the kite has to catch the wind to
generate force to turn the kite into a vertical C shape. If one does
nothing, the kite either continues to stay on its back or in some
fortunate situations, the dynamic of the gust and the water can somehow
let it catch-the-wind to get into a vertical C position. The best way
to let the kite catch the wind is to pull slightly on one of the tip
depending on the position of the kite. If the kite is more to your
right, pull slightly on the left tip, if the kite is on your left pull
slightly on the right tip (the left/right designation is the same as
your bar: pull left end of the bar -> pull the left tip). If the kite
is straight down wind, you can alternatively pull the right or left tip
until one of the tip catch-the-wind - the other alternative is to swim
to one side and then pull slightly on the same tip (swim right and then
pull slightly the right tip).

The transition between the catch-the-wind phase and the
slide-to-the-window-edge phase is also the least understood. Once the
kite has catch-the-wind, one has to immediately release the top tip and
pull on the bottom tip. This action will allow the top tip to catch
more power, allowing it to lift the kite into a vertical C, fully on top
of the water and slide to the edge of the wind window. Failure to
release the top tip soon enough will collapse the kite and it will
likely get into a folding-top-tip position or leading-edge-down
position.

The launching phase is simple, once the vertical C is near the wind
window edge, simply pull on the top tip of the kite to launch it
skyward. In strong wind, one can launch a higher AR inflatable mid-way
between the edge of the wind window and straight down wind.

Hi hung,

there is a very easy trick to it that nobody seems to know.

Here is how I do it:

Once the kite is on its side I hook into the chickenloop
and let go of the bar. Now the wind does the rest for me
I just wait till the Kite is on the edge of the window
and launch it.

This trick works the better the more wind you have to work with,
but I managed to relaunch a 21.5 ARX in 8 mph using this technique.

Thanks

Marko
