With the Shin Aitoku Maru , another attempt was made to either increase the speed of an otherwise conventional cargo ship with the help of a sailing device or to reduce fuel consumption. The concept of Shin Aitoku Maru was developed by Nippon Kokan in cooperation with the JAMDA ( YES pan M achinery D evelopment A developed ssociation). She was built in 1980 by the Japanese shipyard Imamura in Kure . In 1990 it was renamed Nippo Maru and has been operating under its current name Yue You 129 since 1994 .
Another 17 ships were built according to the principle of the Shin Aitoku Maru , in particular the 26,000 ton Usuki Pioneer in 1984 and the slightly larger Aqua City .
Sail arrangement
In mid-1979 the only 83 GRT motorized sailing ship Mini Daigo was launched, on which the sailing system was successfully tested. The two automatically steered rigid but foldable JAMDA sails developed by NKK are attached to a front and a rear mast and are said to bring fuel savings of between 10 and 30%.
