I own a Gin Marabou 9m, used it 3 times so it is in excellent state.
Due to an overcomplete set of kites I would consider selling it for the right price.
It is as new, Kite only. I would let it go for 850.
This kite stays in the air in next to nothing. Ideal as low wind kite on a non-race hydrofoil. Or as a low wind surfkite. Or as an ideal low wind travel kite.
I have tried it with hydrofoil waveboard and TT, works fine with either although it is not a jumping machine.
Will water relaunch (see reviews on youtube) since it drifts like crazy, so not likely you will drop it in the water.
Main disadvantage is as with foil kites; a bit more messy packing this kite when it is raining.
