With the simultaneous defeat of Joachim Murat, two vessels were handed over to the British, but a corvette, two schooners, 24 gunboats, and the two frigates were ceded to Ferdinand, who thus found himself with a modern fleet.
In 1818 the General Ordinances of the Royal Navy of the Two Sicilies were promulgated relating to the entire composition and organization of the Navy: this was the first regulation made by the new kingdom in the maritime field; they constituted various bodies of officers, a nautical observatory, an Accademia di Marina ("Naval academy") and three naval bases, at Naples, Palermo, and Messina.
In 1820 the Navy was considerably strengthened, aligning three divisions with about seventy warships of all types, with a clear prevalence of light woods.
On September 2, 1820, a fleet consisting of the Amalia, the vessel Capri, the corvette Leone, the polacca Sant'Antonio e Italia, and 14 brigantines, reinforced the following day by six gunboats and a bomb ketch, left Naples and was sent to Sicily with a landing force to repress revolutionary movements.
Between 1827 and 1828 the 44-gun frigate Regina Isabella, the 32-gun corvette Cristina, and the brigantines Prince Charles and Francis I entered service.
