The charity continued to support young people, clothing and training them on training ships up until 1944, when war signalled a shift in direction and a decision was taken to instead assist other maritime organisations and help individuals who wished to go to sea professionally, but were unable to find the means financially of doing so. (The average cost of kit for a cadet in 1949 was about £80).
In 1976 the Marine Society consolidated its position of supporting the maritime community even further when it merged with the Seafarers Education Service. The charity continued to provide and develop educational services to seafarers along with the provision of libraries to ships.
Today the charity contiunes to champion the well-being, personal, and professional development of seafarers and now delivers a range of services appreciated by seafarers across the globe. The charity focuses on education/professional development, financial support, book/media services, and advice & guidance.
