"Marabou is 1000x better for water relaunch and therefore I believe a better choice for hydrofoil."
That alone to me does not make it a better choice but a consideration.
For me a better choice for hydrofoil would be a kite that:
1. Drifts better
2. Handles better (The Peak has no agenda of its own, it happily does what I ask of it)
3. Wider Wind Range
4. Low minimum wind threshold
etc...
With my Peak 8 unless I make a mistake or wind drops to nothing, she will not see water. I happily just let go of my handle on a crash and grab it afterwards.
I will always want the kite that gives me the best performance for swell riding and have no problem if one day she gets wet.
Your results may vary....
