Loch Sloy was a Scottish sailing barque that operated between Great Britain and Australia from the late 19th century until 1899.

[2] In the early hours of 24 April 1899, Loch Sloy overran her distance when trying to pick up the light at Cape Borda and was wrecked on Brothers Rocks, about 300 metres from shore off Maupertuis Bay, Kangaroo Island, South Australia.

[6][7] Under the command of Captain Peter Nicol, Loch Sloy was on passage from Glasgow to Adelaide and Melbourne with a load of general cargo and seven passengers, including 2 women; David Kilpatrick, a cook from Glasgow (25), George Lamb, a clerk from Edinburgh, (30), Robert Logan, a piano tuner from Inverness, (40), Alexander McDonald, an engineer from Aberdeen (34), Captain Osmond Leicester (30) and Mrs Leicester (real name Blanche Sophia Meyer-Edmunds, 26, but listed as 30; Osmond's real wife Fermina had been abandoned) of Liverpool, and Rosalind Cartlidge (25).

[5] In the early hours of 24 April 1899, she met with disaster on the coast of Kangaroo Island at the mouth of the Investigator Strait, South Australia.

In the darkness of the morning she ran full on to a reef 300 yards from shore to the north of the Casuarina Islets in Maurpetuis Bay.
