CSI. Possible cause
Hard pull to 5, wake pop. ski bounce with body moving forward, right edge of ski tip digs, body hits water like fly swatter, heavy loading and planter flexion of ankles (no chance for these bindings to release in this direction) weight now back in relation to ski, peak force, ski breaks.
Not sure if this is what happened but It is possible that fall caused failure, and not failure caused fall. I recall reading that skis are weakest bending tip toward bottom. Pull +4-5 G’s in Cessna and wings fall off, only need -2 G’s for wings to fall off. Its all determined by design.
I am recovering from fibula fracture and surgery resulting from slip on wet grass and planter flexion of my ankle. Ankles only go so far. Missing my first ski season in 51 years sucks, I feel your pain, heal fast!!!
