Several lineages are often compressed into the claim that Flower-class corvettes were based on fishing boats. The Second World War class drew on whaler practice, which differs from the naval trawlers and First World War Flower-class sloops also mentioned in the discussion. These working vessels had different hull forms, operating assumptions, and paths into naval service. Treating all of them as fishing boats creates the same problem as calling every armored vehicle a tank. Precise vessel terms make the commercial and auxiliary ancestry of the emergency escort design easier to follow.

Flower-class whaler ancestry and precise vessel terms
The Flower-class design discussion explains why calling the corvettes descendants of generic fishing boats obscures their specific whaler lineage and the roles of trawlers and First World War sloops.
