Installation and Maintenance Requirements - Anchored Sign Buoys • A buoy requires mooring tackle and a heavy anchor, usually requiring a large installation vessel • Annual on-water maintenance inspection for wear and tear of mooring line, requiring the lifting of the anchor to check the lower connection for possible mooring line wear from any abrasion on rocks or in sand etc.
A very large Port Hand Buoy marks the entrance to the port of Port Fairy and as the river is navigable waters i.e. open to the sea, any buoy used must adhere to the maritime IALA AToN system. Port and Starboard buoys would be used to mark the channel. Yellow special mark buoys gazetted and appear in Notices to Mariners.
