Tryal Rocks, sometimes spelled Trial Rocks or Tryall Rocks, formerly known as Ritchie's Reef or the Greyhound's Shoal, is a reef of rock located in the Indian Ocean off the northwest coast of Australia, 14 kilometres (8.7 mi) northwest of the outer edge of the Montebello Islands group. It is named for the Tryall, the first known shipwreck in Australian waters, which sunk after striking the then-uncharted rocks in 1622. Described as "the theme and dread of every voyager to the eastern islands", their location was sought for over three centuries before finally being determined in 1969.
Wreck of the Tryall
The Tryall was only the second English ship to attempt to sail from the Cape of Good Hope to Batavia (now Jakarta, Indonesia) along the Brouwer Route, a route pioneered by the Dutch and used routinely by them since 1616. The Brouwer Route drastically shortened voyage times by keeping ships sailing eastwards in the Roaring Forties for as long as possible before turning north. The captain of the Tryall, John Brookes, grossly underestimated the longitude of the ship, and ended up around 1000 kilometres (600 mi) farther east than the route specified. On turning north, the Tryall found itself skirting the west coast of Australia. Around 11pm on 25 May 1622, it struck the Tryal Rocks and sank. 46 of 139 lives were saved, including Brookes'.
Brookes' subsequent report was extremely vague; it did not even give a position for the wreck. James Henderson characterises this as deliberate obfuscation, an attempt to avoid the blame for being so far off course. Consequently, the Tryal Rocks were originally thought to be well to the west of their actual location. Concerned for the threat to their own ships, the Dutch placed the reef on their charts, but "exactly south of the western extremity of Java according to the statements made by the English sailors". This represents an error of around ten degrees of longitude.
