Hi tigertiger, I live just out side Brisbane Qld but was born on the Brisbane River& spent many years sailing skiff's of allkinds. I have seen a few of these models but never seen them race.
as the name suggests, they originated inSydney & basicly were boats to sail when there was no 18ft racing.There were many clubs formed for juniors &seniors. Like a lot of things ww2 saw the beginning of the end of club racing. There is a book about them that I have seen& I willtry to find it again. As I said I have copy's of 6in & 12 in lines,taken of originals.I havephoto's of them & have built the 6in one myself.I willpost photo's as soon as I can. They were not controlled by any outside means other than, the"Skipper"who was allowed to put them about,& the "Crew"who rowed the dinghy after them. the crew had to be fit as the course covered a lot of water,that was for Harbour raceing. Dam & pond raceing generally had a person walking up & down either side to put them about. That is the general outline of the Balmain Bug's.
toffer.
