Brisbane’s City Cat fleet is getting a new addition, with a $3.7 million, double-decker, high-speed catamaran, are set to be delivered in 2019.

The “Super Cat” will have an upper deck of 16 seats, while the inside will have tables and lounges, USB charging ports and larger windows.

Deputy Mayor Adam Schrinner likened the new vessel to London’s double-decker buses, saying this heralded a new generation of City Cats.
