12-Feet Dinghy Race in Japan
Although it has been almost a century since the first 12-feet dinghy was built in England in 1912, it is still being built by the identical specification in Italy, Netherlands and Japan. The 12-feet dinghy is cherished by many of the Japanese sailors by the name of “A-Class Dinghy.”
In 1933, 12-feet A-Class dinghy became the official racing boat in Japan, and many of the sailing clubs in universities were racing with the 12-feet A-Class dinghies on their sailing regattas. For many years since, these A-Class dinghy have been used in inter-collegiate races and All-Japan races.
However, in 1972, the high-speed 470-Class was nominated as the official dinghy in order to meet the requirements to enter the Olympic Games, and 12-feet A-Class dinghy races were discontinued since.
In 1991, the old sailors who love the 12-feet A-Class dinghy started her “revival race” with only 7 dinghies. Since then, the number of participating dinghies increased annually, and in 2006, 52 dinghies and 303 sailors from 34-clubs have participated in the All-Japan 12-feet A-Class Dinghy Championship.
The specifications of Japanese A-Class dinghy are basically same as Italian and Dutch specifications, but there are some minor discrepancies due to the concepts of the builders, way of construction and the kinds of materials used .
However, Japan 12-feet A-class dinghy Association (JADA) are allowing such minor discrepancies and are admitting participation of those dinghies in the All Japan Championship.
12-feet A-class All-Japan is a race by two-men dinghies under “ The Racing Rules of Sailing 2005-2008”. We have a special rule for minimum sailing weight, which is 140kg, in case sailing weight is less than 140kg, such dinghy has to load enough ballasts to clear the requirement. Measurement for “sail-area” and “sailing weight” will be carried
out as necessary
We have 39-clubs registered and members of the clubs are comprised of old-boys/girls from the universities’ sailing clubs. .Also, these clubs own a number of A-class dinghies that participate in the All-Japan Championship.
