The program will automatically sink and trim the vessel to find the balance condition. Holtrop for ships, Delft 3 for sailboats, Kaper for canoes and kayaks, and DispMode for pre-planing resistance of planing hulls.
Resistance is based on the current hydrostatic balance condition.
Hydrostatics calculations for flat water or for waves. The flat water or waves can be converted to NURB surfaces for rendering. Heeled waterlines and can be displayed for the vessel in the balanced condition.
