Here in Oz, things appear to be simpler. it is generally 4 knots in marinas/harbours etc, 6kn when passing moored boats, within 30 metres of anchored vessels, and in certain rivers to lessen erosion of banks, and then out in the open waters the max is 50kn, except when in ecologically sensitive areas like dugong (manatee) and turtle feeding areas etc, where the 6kn rule again applies. Of course the50kn really seldom possible, but high performance planing boats and jet skis etc capable of those speeds skim along on the surface so don't make much of a wake at speed, unlike those dratted semi-planers....
