5 Righting Arm Curves
Orca3D righting arm calculations were verified using the sphere and horizontal cylinder from previous sections. When the VCG was located at the centroid of the shape, it was verified that the righting arm curve remained 0 for heel angles of 0-90 degrees. For VCGs not at the centroid, the following plots were produced from Orca3D data. As expected, the righting arm curve followed a sine curve.
Figure 5.1 Righting Arm Curve for 10m D Sphere VCG = -1.0m
Figure 5.2 Righting Arm Curve for 10m D Sphere VCG = -3.0m
Figure 5.3 Righting Arm Curve for 6m D Horizontal Cylinder VCG = -1.0m
Figure 5.4 Righting Arm Curve for 6m D Horizontal Cylinder VCG = -2.0m
