The Brisbane City Cat vessels are catamarans. They are named after the Aboriginal place names for various parts of the Brisbane River and adjacent areas. I have been taking these around my city ever since I can remember, but I know for a fact they have been around just after I was born, in 1996. These days they are decked out with Wi-Fi services, multiple vessels on the river and digital payment systems. Oh how times have changed! Soon they may even have block chain technology ;) another great win for Brisbane City
