Austal 40 metre high speed passenger catamaran use single waterjet leaves the berth

1 engine damage but still plying the route?

The common problem of any catamarans which had water-jet propulsion system is that engine can easily shut down, so thats the problem probably (engine was shut down), but can easily bu turned on again and you can make turn without one water jet ;) Here in Croatia, we have one catamaran which was driving in Hong Kong

engine damage

why only using single jet?
