PROSPECT OF SAIL-EQUIPPED MOTORSHIP AS ASSESSED FROM EXPERIMENTAL SHIP "DAIOH"

This article suggests an approach to the realization of a sail-equipped motorship based on the results obtained from wind tunnel tests, on-shore tests and sea trials of the experimental-ship "Daioh" conducted by the joint efforts of Nippon Kokan K.K. and the Japan Marine Machinery Development Association. Much technical data on sail performances was obtained through systematic wind tunnel tests. The sailing equipment was first mechanized to meet the various requirements, installed on board "Daioh", and tested, and a power gain estimation method was verified by the sea trials. The economical aspects off a 10,000 to 35,000 DWT Bulk Carrier were also studied by utilizing the power gain estimation method. This then is a report on the successful termination of the first stage in the development process.
