A more thorough explanation:

Definition: Vice-admiralty refers to the office of a vice-admiral or the district over which a vice-admiral has jurisdiction.

For example, during the colonial period, the British government established vice-admiralty courts in the American colonies to enforce maritime laws and collect customs duties. These courts were presided over by a vice-admiral who had the power to hear cases related to piracy, smuggling, and other maritime offenses.

Another example of vice-admiralty is the current structure of the Canadian Navy, which is divided into four regional commands, each headed by a vice-admiral. These vice-admirals are responsible for the naval operations and readiness of their respective regions.

Overall, vice-admiralty refers to the authority and jurisdiction of a vice-admiral, whether it be in a historical or modern context.
