The neutral stability of parametrically excited cross-waves in a rectangular tank is studied. Model equations considered include complex coefficients describing dissipation of the side walls of the tank and at the wavemaker. The results of this study are compared with the available experimental data. It is shown that for certain experimental conditions, the dissipation at the wavemaker becomes important and sometimes dominant. Analysis of the experimentally obtained neutral stability curves and their comparison with the present theory provide an opportunity to estimate the complex dissipation coefficients.
