In the Royal Navy, the rank of Master of the Fleet denoted the sailing master of a fleet flagship, or the senior sailing master in a fleet. Examples include John Bowen (Master of the Fleet during the Glorious First of June 1794), Ian Hogg, and John H. D. Cunningham. The title has been used outside the Royal Navy, such as in Ultramarines and other science fiction, and for the captain of the Belle of Louisville.
