...Andrew Ricks; Michael Gorts Morabito; Raju Datla _ A stepped planing hull is a type of high-speed boat with a transverse break in the bottom of the hull. The step allows the hull to run at a higher trim angle, and also reduces the wetted surface area at planing speeds because of a pocket of air...

... limitation of the method. Better accuracy in prediction of sway force and yawing moment is observed at a trim angle of 6° and roll angles of 10° and 20°, especially for small yaw angles. The main sources of errors are found to be as follows. 1) Flow separation from the wedge apex in negative roll angle...

This wide range of parameters is significantly larger than most current models. The empirical method is modular, allowing for substitution...
