The Sound has long been used for navigation, linking ports such as
Oban and Tobermory with the Atlantic. As such, there are a number of wrecks in the Sound. The
SS Thesis was a cargo
steamship which was wrecked in October 1889 in the Sound. The
SS Hispania, was a
Swedish cargo ship that sank on 18 December 1954 after striking a rock. The wreck of the
SS Shuna is located in the Sound. The Shuna was a Glasgow steamer, owned by Messers Glen & Co., that was carrying a cargo of coal and iron from Glasgow to
Gothenburg when it struck on the Grey Rocks during a storm in May 1913 and subsequently became a total loss. In 1973, divers from Bristol discovered the wreck of
HMS Dartmouth, a
fifth-rate ship of the
English Council of State. On 11 April 1974, the 1690 wrecksite was one of the first to be designated under the
Protection of Wrecks Act. It was redesignated on 25 June 1992. The site became a
Historic Maritime Protected Area in 2013. ==Geography==
