If we are speculating I'd say landed collective not fully down, moved the cyclic and it started to rock on the toes due to a forward C of G issue (overloaded). Bit of panic, snatched the collective and binned it.
Didn't really notice too many white caps or spray from the water so not that windy or at least nothing the AS350 couldn't handle.
New to type or just a low timer?
Agreed 100%
