Ronco was a French Illyrien or Friedland-class brig built at Venice and launched in April 1808. HMS Unite captured her less than two months later. The Royal Navy took her into service as HMS Tuscan. She served in the Mediterranean and participated in one action that earned her crew a Naval General Service Medal. She was first offered for sale in 1816 and sold in 1818. At that time mercantile interests purchased her and she became a whaler, making six voyages before being condemned as no longer seaworthy in March 1840 and sold in April during her seventh voyage.
