In 1942, the Girls' Naval Training Corps was formed as part of the National Association of Training Corps for Girls, with Units mainly in southern England. Its objective was congruent with that of the Sea Cadet Corps, teaching girls the same seamanship skills as the SCC taught the boys.
By 1952 The Girls' Naval Training Corps was 50 Units strong and in the late 1950s changed their name to the Girls' Nautical Training Corps.
In 1963 the GNTC became a colleague organisation with the Sea Cadet Corps, often sharing facilities such as Raven's Ait (then also known as TS Neptune) until 1980, when the organisation became part of the Sea Cadet Organisation, first with a name change to Girls Nautical Training Contingent, this continued until 1992 and the organisation was absorbed.
