What SEA Cadets does

Sea Cadets is a UK registered charity operating under the umbrella of Marine Society & Sea Cadets (MSSC), tracing its origins to the Marine Society founded in 1857. It delivers maritime-themed youth development and personal training to approximately 15,000 cadets aged 10-18 (plus 9-14-year-olds through the On The Water programme) via a national network of roughly 400 local community units staffed by approximately 9,000 volunteers. Programmes span Junior Sea Cadets, the core Sea Cadets curriculum, Royal Marines Cadets, and SeaVenturers, and award recognised qualifications including Royal Yachting Association (RYA), British Canoeing, BTEC, Duke of Edinburgh's Award, and ILM leadership credentials.

The organisation operates a fleet of seven training vessels, most notably the 58-metre flagship tall ship TS Royalist (launched 2015), which delivers 35 week-long offshore voyages annually carrying 24 cadets each. Supporting infrastructure includes the Cadet Training Platform — an online portal for virtual learning, qualification tracking, and module completion introduced during the COVID-19 pandemic — and the Trinity 500 pulling-boat flotilla programme. The charity is governed by a board with Jeremy Penn as Chair and Guy Holloway as Chief Executive, registered in England and Wales (313013) and Scotland (SC037808), with headquarters at 202 Lambeth Road, London.

Revenue is generated entirely through charitable giving rather than commercial sales. Income streams include individual donations (with Gift Aid), trust and foundation grants, legacy giving, challenge-event fundraising, and affiliate referral income from platforms such as easyfundraising, Amazon Smile, Savoo and Giveacar. The TS Royalist Appeal is a flagship fundraising campaign (raised £587,000 toward a £787,000 target for Phase 2 of the ship's refit by October 2025). Go-to-market is community-led: recruitment of cadets happens through local unit presence, school outreach, and volunteer networks, while donor acquisition is driven by digital channels, national events (Trafalgar Day, National Cadets Week), and earned media. Cadets participate free or low-cost, and the charity reports substantial social impact including 38,563 days of community volunteering in 2019/2020.
