Studies of temporal evolution of turbulence, generated by a moving boat are carried out in field
experiment. The geometrical scales of the turbulent area are retrieved from experimental data and the
temporal dependence of the wake width as shown to be described by a 0.4-power low. Similar
dependence was obtained in wave tank experiment on modeling of spreading of a turbulent layer excited
by a pulse source. A qualitative model of an initial stage of wake spreading is suggested.
