Not sure if it is of interest to anyone but this weekend is the Cardiff Harbour Festival.
There is Zap Cat racing on Saturday and Sunday
Firework Displays Saturday and Monday
And various other events
There are a few launch sites in the area but unfortunately the short stay pontoons in Mermaid Quay are closed most of the day Saturday and Sunday for the Zap Cats.
If anyone does happen to be coming down let me know if you want to meet for a beer.
