There have been papers about improvement of the ship performance by the representative ships, for exarmples, the IDEMITSU-MARU, the TOKYO-MARU, etc. There are, however, few papers about ship performance of the whole ships. The data of ship performance were collected since 1963 by SEMPAKUMEISAISHO, which holds all of ships registered in Japan. This paper shows the change of principal dimensions, sea speed, maximum continuous output about the collected crude oil tankers. Analysis results for ship performance are shown with some assumptions. The resuits show that the larger the ships was, the better the propulsive performance was and it is found mainly because of smaller viscous resistance by larger Reynolds Numbers. The results show that the ships, which are built recently, have better performance.
