In 1976 the society amalgamated with various other maritime charities with similar aims, including the Incorporated Thames Nautical Training Trust (Thames Nautical Training College located four times on a ), the Seafarers Education Service, the Sailors' Home and Red Ensign Club, the Merchant Navy Comforts Service Trust and the British Ship Adoption Society. The merger of the Seafarers Education Service with the Marine Society at this time was hugely significant and helped to ensure the continued relevance of both operations. The Service consisted of the Marine Society College of the Sea and Seafarers Libraries, and had been inaugurated in 1919 by Albert Mansbridge who had earlier founded the Workers Educational Association. Both the College of the Sea and Seafarers Libraries continue to flourish today.
