It is well established that modulational instability enhances the probability of occurrence for rogue waves if the wave field is long crested, narrow banded and sufficiently steep. As a result, a substantial deviation from commonly used second order theory-based distributions can be expected. However the spreading of the wave energy over a number of directional components can notably reduce the effect of modulational instability. In order to achieve a better understanding on the influence of wave directionality and its implication for design work, numerical simulations based on the truncated potential Euler equations were used. Results show the existence of a transition region between strongly and weakly non-Gaussian statistics as short crestedness increases.
