I'm living proof.

Before this new theory came out, I always worried about the fast storm which changes the wind direction radically in 10-20 hours, leaving a set of (say) 30 foot waves crossing a set of 20' waves at about 90*, creating big crazy waves and super deep troughs with no warning. "Fastnet Force Ten" from 1979 or the "Queen Anne's Storm" between NZ and Fiji a few years ago are two famous examples we have read about.
