It is critical to satisfy various requirements for the model when running the Planing Hull Savitsky Prediction. These are:
| - | MUST ONLY represent the planing surface up to the chine; a hull surface that includes the topsides can be split at the chine by selecting the surface, then selecting the Surface menu > Surface Edit Tools > Split at Isocurve, finally selecting the curve representing the chine and press Enter |
| - | MUST ONLY represent half of the hull |
| - | MUST have a transverse coordinate of 0 on the centerline |
| - | MUST have a surface normal direction pointing outward into the water. The surface normal direction can be verified by selecting the surface, then selecting Direction from the Rhino Analyze menu. |
