| Abstract: | Based on dozens of the speediness test data of full form ships , through the analysis of the traditional estimation formula and the study on formation cause of the ship＇s wake, part of ship form parameters and dimensionless quantity were select-ed as impact factor to establish the corresponding mathematical model .A new, more precise full form ship wake fraction estima-tion method was proposed by stepwise regression , whose accuracy and correctness were verified by some computation . |
