Bury Lake Young Mariners (BLYM) is an award-winning youth sailing charity run entirely by volunteers, based at the Rickmansworth Aquadrome on Frogmoor Lane in Hertfordshire.

For more than 40 years the club has used sailing and related water sports to develop life skills in young people, bringing over 7,000 participants onto the water each year.

The club operates from Bury Lake within the Aquadrome and maintains a diverse fleet of modern sailing dinghies — including RS200s, Lasers, Picos, Toppers, Wayfarers, Coypus, and Funboats — alongside nine powerboats used for rescue and coaching.

BLYM runs general sailing sessions, racing, and structured RYA courses, and describes itself as an all-inclusive club open to new members.
