An investigation of SWASH ship forms and resistance

An investigation on the ship forms and resistance of a new ship type named as SWASH,small water-line single hull,was launched.According to the analysis of the ship forms and the design calculation,two design plans of the SWASH ship form and the simple moulded lines of one was developed out.Based on the resistance results from the both the theory calculation method and the empirical formula,together with the model tests results,researches on the resistance performance of the present SWASH were carried out.The component of the resistance,the influence on ship resistance from the ship hull gometrical parameter,the immersion depth and the strut shape were also discussed according to the calculation results by present methods.
