Due to the lack of a detailed stipulation about the load design in the Chinese code concerning the yacht harbor,we carry out a research on the wind load,wave load,current force,mooring force and impact velocity by referring to the standards of different countries both at home and abroad.The research reveals that calculations of Chinese standards for the wind load,wave load and current force are reasonable，while that about the vessel’ s mooring force is not quite appropriate,and it is suggested to refer to the USA and Australian standards.As for the calculation of the impact velocity,the Australian standards is suggested to be referred to.
