Just reflecting the first experience trying to galactical on a Monofoil + Peak4 (not sure yet, if a bit too much)
Or in other words: "Progressive Relaunch Simulator".
I was on about 12 m flying lines and therefore together with a 5 m² Peak about 17 m system lenght, which has shown to be still relevant to long so allready shorted by 2 m for the next try.
First try it nearly hits me but most time I passed behind, but still quite far away to do a serious especially flying one.
When the kite ended close to me I mostly directly winded up to do a drift start but sometimes it was even possible to start it just buy swimming around it and then relaunch it the classic way.
Here my impression of quite some drift (re)launches:
It is maybe more stable, easy and effective to just let the kite drift away on its back with absolute no line tension. The wind hooks pretty well from the back into the leading edge and the main benefit is the kite drifts and pulls itself permanently out of the water. So different technic as I so with closed cell where you allways try to keep front line tension having the kite sittin on its trailing edge. But maybe pretty important for the Peak4 you have to have it first in this position:
Ready to release line tension and to unwind fast the lines I would recommend to grab the A-center bridle line (as with closed cell) pull it out of the water to release most of the water from the tip cells as symetric you can do and take care to not launch one tip totaly as you can expect it will flip over. When done release all imeadiately and let it drift. When it is drifted all the way and you regain line tension, take care to have it most on the front line, taking the trimmer in the hand to pull it up.
