Added Mass and Damping Graphs

Added mass and damping coefficients can be plotted against wave frequency or wavelength for a given ship speed. Hydro can plot either the total value or the zero speed component of the coefficients. As the forward speed components are heading dependent, various headings may be plotted together on the forward speed graph.

The coefficients that can be plotted are:

The graph shows a typical added mass and damping graph, plotting A33 vs. Wave Frequency at 10.0 knots.
