In this paper the ship's speed performance deterioration caused by aging is mentioned. Ship's speed performance decreases generally according to the increase of the frictional resistance caused by ship's bottom fouling. In order to examine the relation between the performance and the fouling, it is necessary to analyze the data recorded over the long period. However, there are few cases that the data have been analyzed quantitatively. It is very important for ship's navigators to estimate the aging-rate. Therefore, the author discussed the results of the analysis of the speed trial data obtained on the T. S. Wakashio-maru during the past eight years.
