...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...
