Yes. Thin high AR high span wings are more likely to crack on bad landings. A bad landing from height is not comparable to the loads when you are racing and pushing on the foil in the water. Landing hard on your foil after a big jump especially flat will put a lot of pressure near the connection between wings and fuselage. This is where you will see most cracks from jumps.

Hi Gunnar,
agree that high AR with span of 60 cm or more have the highest risk to break due to lever length.
But would also agree with evan:
In my eyes, on a full speed crash or when ventilating with one wing tip under full load will cause higher torsional loads to wing-fuselage-strut connection than most bad landings can cause.
I have seen a solid prototyp breaking during a jump but the guy said, that he felt the crack during the takeoff, when one wing tip was out and the other still in the water, not during the landing.
But also agree with: Better take a less than 100 % race orientated foil for jumping. I will go for the old levitaz bionic (haven't tried the new one yet) as used bionic parts are getting cheaper now on the market and the levitaz is for sure one of the most solid race foils. Accepting it is also not the lightest.
