I may have missed something but on entering Manly Harbour (Queensland) I notices that the 6 Knot sign have been changed. They used to have "No Wash" under them but this seems to have been covered up. I do look at this as I got fined by the water police for making a wash with my boats dingy when motoring at much less than 6 Knots (Don't ask me how as I have no idea either), and at the time was lectured about the harbour being 6 Knots NO wash. The fact that technically you could fine every boat going up and down the main channel for making a wash didn't matter.

So has the rules changed? Why the change to the signs?
