Note on breather type solutions of the NLS as models for freak-waves

Some breather type solutions of the NLS equation have been suggested by Hen derson ct al. [to appear in Wave Motion] as models for a class of 'freak' w ave events seen in 2D-simulations on surface gravity waves. In this paper w e first take a closer look on these simple solutions and compare them with some of the simulation data [Henderson et al. to appear in Wave Motion]. Ou r findings tend to strengthen the idea of Henderson et al. Especially the M a breather and the so called Peregrine solution may provide useful and simp le analytical models for 'freak' wave events.
