The conventional definition of rogue waves in the ocean is that their heights, from crest to trough, are
more than about twice the significant wave height, which is the average wave height of the largest one-
third of nearby waves. When modeling deep water waves using the nonlinear Schro¨dinger equation, the
most likely candidate satisfying this criterion is the so-called Peregrine solution. It is localized in both
space and time, thus describing a unique wave event. Until now, experiments specifically designed for
observation of breather states in the evolution of deep water waves have never been made in this double
limit. In the present work, we present the first experimental results with observations of the Peregrine
soliton in a water wave tank.

Today, there is widespread consensus on the existence of
rogue waves in the ocean [1­3]. A number of mechanisms
