An admiral uses the flag of St. George, a white flag with an upright red cross on it. It is flown at the main’mast at the upper extremity, or if the ship has less than three masts it is flown at the top of the loftier of the two.
A vice-admiral flies a similar flag with a red ball in the upper canton next the staff.
A rear-admiral flies a similar flag with a red ball in each of the two cantons next to the staff.
