Ship researchers devote great efforts towards improving hull form for minimizing ship resistance which reflects on capital and running cost by reducing fuel consumption. Benefits of bulbous bow were shown reduction of wave resistance. However, further research work on different bow shape is needed. This paper offers a study of how minimizing the wave making resistance is due to using new innovative x-bow shape. The work involves a numerical simulated flow around hull model to estimate ship resistance using computational fluid dynamics, CFD. Validations of experimental data for wave making resistance for series 60 hull with conventional bow are done. For accurate output, numerical study is performed to choose an optimum turbulence model. Geometrical modification using Rhinoceros software on the series 60 hull by adding delta-type bulb and new innovative X-bow on the fore portion are made. Similar works are done using KCS and DTMB 5415 hull models. The work has shown significant reduction in wave making resistance due to using the X-bow for the range of Froude number from 0.18 to 0.45, if compared with the original hull of series60, KCS or DTMB 5415 for the same range.
