SPEED IN MAIN CHANNELS Maximum: the speed which does not result in the collapse, deterioration or damage of the edge of the channel. Minimum: the speed commensurate with maintaining the vessel manoeuvrability. All vessels sailing in the vicinity of dredgers and buoy-laying vessels operation areas must reduce the speed to the minimum. Mariners must take into account the bend in the Km 39 junction, the ferry routes and the hard bottoms.
