From 1976 to 1991, you may want to contact the organizers of the Hong Kong International Dragon Boat Race (
[email protected]) as the Hong Kong Tourism Board sponsored the major push to the modern era of dragon boat racing. After 1991, when IDBF was formed, you can always contact them (
http://www.idbf.org/contact).
Organized club competition in Hong Kong and southern South-East Asia has been around for a long time. In term of modern racing outside the area, that was a big push from this Hong Kong Tourism Board, with their donations of teak dragon boats around the world. Some places picked it up quickly, others did not. In Canada, there were new clubs created for dragon boating (e.g. CIDBFS aka Dragon Zone) while existing canoeing clubs adopted the sport (e.g. False Creek Racing and Canoe Club).
