The red propellers I saw at Sydney Darling Harbour. I wonder how much speed this things can top. Don't think it would break the world's speed record. I can not believe that these antiques are still being used. Can you imagine how old these things are? I don't know much about boats but it looks ancient to me.
Ferries in the Sydney Darling Harbour transports people everyday. There are people that rely on the ferry to transport them across the Harbour to work. They probably get sick of using it everyday and seeing the same thing day in and day out.
Tourists uses them to see interesting attractions all over Sydney. Some attractions around the Sydney Darling Harbour area is only accessible via Ferry. Such as the Shark Island. This island is great for a picnic, a quiet gentle stroll, fishing and some people scuba dives.
The ferries are certainly a crucial part of Sydney's transport system. It helps both local and tourists arrive at their destination, at the same time enjoying great harbor views.
