St Florentine was a 60-gun coast guard vessel in service in support of the French Navy during the early days of the Seven Years' War, before being captured by Britain in 1759 and commissioned into the Royal Navy as HMS St Florentine.
Surplus to Navy requirements by 1771, St Florentine was decommissioned and sunk as a breakwater off the port of Sheerness.
