Notes
Dimensions are given relative to coordinate system origin, except for M Trans and M Long which are given relative to the resultant waterplane. Accuracy of calculations is affected by the density of points in the surface mesh. All coefficients are based on LWL and maximum draft above. The accuracy of the sectional area curve, maximum section area and location, and prismatic and midship section coefficients are affected by the surface mesh density, and the number and location of defined stations. In addition, for trimmed waterplanes the sections are no longer exactly perpendicular to the waterplane, also affecting accuracy. The displacement-length ratio is defined as the computed vessel displacement in long tons divided by the cube of one-hundredth of the waterline length in feet. The moment to change trim is computed with the assumption that the center of gravity is at the flotation plane.
