Know what you mean Martin, it's a bit like the yacht sailers here, they all sail the same boats and they all turn up, take over an area for most of the day and if you dare to try and launch a boat while they are racing watch out. It's quite comical really, watching them all marching up and down the pond like bunch of ducks with their TXs held out the same way. They can get real serious with the racing as well.
I was in a large boat club years ago and there were always arguments between the yacht and powerboat guys and it was always the old (I can say that 'cause I am now) serious yachting codgers whingeing about their allotted day having not been suitable (weather wise) and wanting to take the powerboat day as well because the weather was nicer. Needless to say, in the end, the power boats went their own way, along with the sail and scale guys and the club ceased to exist. It just became too snobby and separated and no fun any more.
Even now, the scale modeling in NZ is pretty dead and if you look at the Auckland club website you'll see why.
https://marinemodellers.org.nz/. No info, no updates, no new pics etc. Some of the guys who were in this club were the same as were in the afore mentioned club 30+ yrs ago and they were old then. I tried to contact them and got very little back other than the might be there on Sat mornings for a couple of hours. Why even bother maintaining a web site?
You are pretty much on your own now with model boats here and hardly anyone sells boat parts any more, (Ebay and Aliexpress are the modelers friends now)
