Measurement data, either measured from a hull or entered by hand will automatically be compared with the limits of the chosen speed prediction methods.

In the Data window, measurements that are outside the valid range for a particular method will be highlighted in the column for the method in question. Data in red indicates that the value is too low, whilst data in orange is too high.

Please note that in some cases, the valid range for a particular method may be in terms of a ratio or coefficient such as B/T. In such a situation, if the B/T ratio was too high, the beam would be highlighted as being too high and the draft would be highlighted as being too low. In some cases, this can cause a value such as beam to be both too high and too low; this would occur if both B/T and L/B were too high.

Please refer to Appendix B Applicability, section Dimensions on page 58 for details of the valid ranges for the different analysis methods.
