I would relaunch my torch 2006 C kite just as easy under those conditions.
If you purposefully rest the kite on the edge of the window after waiting for the wave to get through,if you stand up so that your lines aren't in the water and the current is keeping them nice and tight(your body is not drifting downwind with the kite) does that actualy demonstrate the relaunching capacity???

.
Don't know if it relaunches easily but that is prime bogus.
Crash the kite hard on the leading edge so it gets nicely wet, let it get washed over by a couple of little waves so it drifts full downwind of you (it always does when I crash mine in the surf) then show us the relaunch

Will await the vid impatiently



ps:I have nothing against the noise and I have seen plenty relaunch easily in the surf but that vid irritated me, it is like the army advertising the airforce by always showing footage of jet fighters
