On 24 November 1831, the St. Patrick grounded on a sand bar in thick fog off Hook Tower in Waterford at the end of her voyage. There were no casualties, and she was not commanded by her normal captain on her fateful voyage. An unnamed newspaper said:Following the disaster, the wreck was not refloated or even salvaged, but a new ship by the same name was ordered. Divers in 1989 reported finding pieces of brass on the seabed in 9feet-12feet of water around 52°9' N, 6°55' W. Although this is close to where the vessel is reported to have sunk, many ships have also been lost in that area. Her replacement RMS St. Patrick also sank nearby seven years later.
