The Knowsley

The Knowsley

Only dived once previously by Craig James and Peter Balalas in 2004, this wreck has now been identified as most likely the Knowsley.

The wreck lies in 88m of water in the Rottnest Ships Graveyard, and was modeled by the WreckSploration team in February 2024

From Dr Ross Anderson (WA Museum):

  • Length overall: 50.85 aligns closer to Knowsley (Tocopilla 48m, (2.85m difference) Knowsley
    51.29 (44cm difference)) – no other wrecks in Graveyard in this size range ~50m length
  • Decks: Two decks – Knowsley recorded as having 2 decks, Tocopilla not recorded as having 2
    decks (Worsley and Green)
  • Quarter deck: collapsed over rock at stern but coherent section measures 14.3m maximum
    length—Knowsley quarter deck length 13.4m = 90cm difference – consider OK match in
    length for partially collapsed structure
  • Tocopilla not recorded as having a quarter deck
  • Bow: Fits the definition of a ‘straight’ raked bow, as opposed to clipper bow
  • Masts: Fore and Main lower masts only, no pole masts or mizzenmast. Without photos of
    either wreck in hulk form cannot compare/ confirm mast/ deck layout – inconclusive.
  • Modifications: Site appears to have had main deck hatches and some main deck beams and
    most if not all lower deck beams cut out, to facilitate access to coal cargo when bunkering
  • Summary: Site is considered most likely to be iron hulk Knowsley.

Built in 1864 as Knowsley, then known as Euterpe between 1879-1895 and Anna Maria Schwalbe between 1895-1913, before being renamed back to Knowsley in 1913.
In 1897 the hull was damaged in gale force winds when the barque tried to leave Albany harbor with a heavy cargo of railroad ties, and it was after this time was used as a coal hulk.
The Knowsley is one of the oldest wrecks in the Rottnest Graveyard, built in 1864 and scuttled on 3rd of October 1923

Funding for this dive was contributed to by WA Heritage Council, Dodd Group, Mondo Electronics and Advantage Air.
