One of the most exciting and sometimes scary ferry rides is the Manly to Circular Quay, Sydney commuter runs. The ferry has to pass by North and South Heads at the entrance to Sydney Harbour. Below is a video filmed on a wet and stormy day on run past the Heads in 2007.
The Manly ferry looks like it is surfing the waves.
Years ago when I was a teenager my parents took my sisters and I by train journey to Cairns to visit my fathers family. My aunt and uncle thought a ferry trip out to Green Island would be a nice day trip, it was until it was time to return back to the mainland. A storm came up as we were heading back to the wharf. Auntie was getting worried when my sisters and I went out on deck but my mother assured her we were ok as living in a harbour city we were quite use to riding ferries and especially the Manly ferry.
