SS Carnatic was a British steamship built in 1862-63 by Samuda Brothers at Cubitt Town on the Isle of Dogs, London, for the Peninsular and Oriental Steam Navigation Company (P&O).The composite construction hull (iron-framed and wooden-planked) was fitted with square-rigged sails and a 4-cylinder compound inverted steam engine by Humphrys & Tennant, providing 2,442 hp (1,821 kW) to a single propeller.On 12 September 1869, she ran aground on Sha`b Abu Nuhas coral reef near Shadwan Island at the mouth of the Gulf of Suez in the Red Sea.At 11 a.m. the following morning, after 34 hours on the reef, Captain Jones had just given the order to abandon ship and the first four passengers had taken their seats in one of the lifeboats when Carnatic suddenly broke in half.The survivors made it to barren island of Shadwan, where the next day the Sumatra rescued them.Carnatic was carrying £40,000 worth of gold (well in excess of £1,000,000 in modern terms), so the wreck was the subject of a salvage operation two weeks later.
