Abstract:
Regarding the increasing application of fast boats in the world, studying the motions and dynamic performances of these boats is consequently effective and vital.Vast activities take place in all over the world yearly. General performances hull tests occur in marine laboratories such as Wave maker and carriage. Model hull test is one of effective branches of the naval architecture engineering. This method is also based on dimensional analysis. In this thesis,after understanding the waves and the methodology, a computer program was developed to predict motions of a high speed craft in regular and irregular waves (Heave and Pitch). Slamming is one of the most important parameters on a high speed craft motions so In a part of the thesis I added slamming to the equations of motions and based on I devoleped my computer program. Finally, I investigate on effects of slamming on the crew performance and compared the results of the computer program with those criteria
