Comparing the operation of liner boats with that of timber carriers, the authors have tried the rationalization of timber carriers. During one round voyage of American-log-carriers and Lauan-carriers, their operations are examined. Besides conditions of operations at Nagoya and other discharging ports are examined. The number of ships for statistics was as follows: Nagoya Others American-log-carriers 66 54 Lauan-carriers 263 49 The term was about one year, from Nov. 1969 to Oct. 1970. As the result of investigation, they found that the great obstacle of rationalization was the high ratio of anchoring hours to one round voyage. Especially the shortage of anchoring hours at discharging ports was necessary. The main cause of the extension of anchoring hours is that the ratio of waiting hours to moor and waiting hours to discharge cargo is high. The solution of these problems are enlargement of timber ponds, consolidation of port facilities, rationalization of cargo-working and security of skilful laborers.
