Coast dynamics resulting from the interplay of long vessel wakes and short background wind waves is studied experimentally in tideless conditions of Gulf of Finland. An attempt of qualitative study of impact of each wave system on a coast is made. Special attention is paid to two parameters: the change of sullage volume and the change of the coast profile shape, which is defined as an exponent in the power approximation of the coast. The analysis of these parameters and their variability for ship and wind waves demonstrate peculiari-ties of the ship wave and wind wave effect on the coast.
