The Mersey class was a class of Admiralty naval trawlers built for the Royal Navy (or other government institutions) prior to World War II. Admiralty meant they were built for military service as opposed to conversions of existing boats. The majority of the vessels were built to a standard design but a few included in the class were built differently.
Some were completed as fishing vessels rather than for military service. Many went on to be used in various roles during World War II.
