The Cutter Patch Anchorage:
Most skippers approach the Cutter Patch from the NW, leaving the beacon at the NW tip of the shoal to port and maintaining a heading approx SE by S and a depth of 4m or more, until they reach the indent in the sea floor with the lighthouse bearing approx 60° . Turning towards the lighthouse, a location can then be selected in a sandy patch and at a depth appropriate to the vessel. Access to or exit from this anchorage can be made through to the Sultana Passage or to the South via Marion Light, although the latter is not recommended if there is anything more than a moderate breeze from that direction.The above photo shows Troubridge Island taken from the Cutter Patch anchorage. Comments: This anchorage provides shelter on the western side of Troubridge Shoal, SW of the old lighthouse and about 1/2nm from the shore. Troubridge Island, being some 3nm off shore, is sufficiently remote to give a real sense of solitude. It is an alternative anchorage to Edithburgh. Wind and tide can provide some interesting variations in headings while at anchor. Note that the light has been extinguished and a new light established on Marion Reef approx 2nm to the S. A visit ashore to the island is well worth the effort. Permission should be obtained from The National Parks and Wildlife Service before going ashore.The lighthouse, made of cast iron, is the oldest in South Australia and is no longer lit.
While it is still quite tenable in a SW wind, better conditions can often be found approx half a mile to the SW, just off the NE edge of the adjacent shoal.
If proceeding towards Marion Reef, please note that the Marion Reef light postion is 35 09.210 S 137 49.023 E (WGS84) ie: 0.2 NM west of charted position.
