Stability analysis, virtual study model on a 1/100 scale, hull centre position and metacentric radius. Obtaining the centre of gravity for heels up to 12°, the metacentric radius is obtained from the intersection between the action line of the centre of gravity at 12° of heel and the vertical centreline. The analysis could be done with the help of AutoCAD (calculating the volume center for 12° heel while maintaining the design displacement at heel), this is achieved by making an approximation with volume cuts and consulting properties until the design displacement is equal to the heel. The model allows to observe through the pendulum system how the center of the hull is positioned for the different heel angles. The data extracted are: metacentric height 6.406 m and metacentric radius 3.0104 m. The virtual model was extracted from a practical work of the Higher Technical Degree in Shipbuilding at Isft 193, project and idea Mauro Lujan Saghessi. To clarify, the transverse metacentric radius is considered practically invariable for heels up to 10°, the angle has been altered and maximized for visualization improvement purposes.
