From 1545 to the Deanes
Early salvage
The original plan had been to raise the Mary Rose on 3 August 1545, 15 days after her loss. She had sunk in reasonably shallow water, with her masts protruding above sea level. Mary Rose Trust Venetian salvage operators planned to run cables under the hull, pulled taut by two larger vessels, the Sampson and the Jesus of Lübeck. The Trust notes that the Swedish Vasa was later raised using this technique. Mary Rose Trust By 9 August, all that had been achieved was the snapping of the Mary Rose’s masts. After six more days of effort, they had still failed to move her. Mary Rose Trust
Almost as soon as the Mary Rose sank, Greenwich says, people tried to lift it, but they could only manage to raise the masts. Royal Museums Greenwich The Mary Rose sank in about 40 feet (12 metres) of water, and almost immediately attempts were made to raise the vessel. Those efforts proved unsuccessful. Britannica
Italian salvage diver Piero Paola Corsi was paid to recover guns from the Mary Rose. His salvage dive team was led by Jacques Francis, a Guinean diver who worked for Corsi. Mary Rose Trust Work on the Mary Rose concluded in 1552, and the wreck was finally abandoned. It would not be until 10 June 1836 that the Mary Rose would be seen again by human eyes, the Trust says.

In 1836, the Trust’s timeline says, Gosport fishermen reported nets being snagged in the Solent and the Mary Rose was re-discovered. A Deane salvage operation followed; from 1835–40, many of the objects recovered were turned into souvenirs. Mary Rose Trust In 1836, divers recovered a cannon and other guns, but the wreckage was soon forgotten. Britannica
The same cable-and-hulks idea, the Trust notes, was later used to raise the Swedish Vasa. How the two hulls were conserved is on the conservation page.
