I wonder how many prospective FM's offer to do the job for free, "just to get the experience"?
Kap, I dare say quite a few would like to try, but seeing as Sydney Ferries is a statutory government authority, it's not quite the accepted practice.
I'm not saying it doesn't happen in the charter vessel industry, but ferries are (almost) a unique industry. However, it is possible to gain access to the bridge of one of the ferries if you know the right people. If you are really lucky, they may let you 'steer' under supervision.
That is fun!
