It was the 36" version. I don't think longer balsa strip was available then, in any case I was on a budget.. The floats are tiny pontoons very similar to the airboat shown earlier. I saved for a couple of months at pocket money (1/6d p w) then a paper round. I was 15 years old at the time. Plenty of competitions in this country and abroad Oz and N.Z., for the Tomboy. I have a German magazine plan of it too.
