4th Thames Ditton (Ajax) and 1st Cuddington (Warspite) Sea Scouts are two of the countries leading Sea Scout groups. Both are recognised under the Royal Navy scheme for the excellence of their standards both on and off the water. Their combined water activities, as well as those provided for other Scout Groups and related organisations, are known as the Warspite-Ajax Scout Boating Centre. The Centre is authorised to deliver RYA, BCU and BR courses. Both groups are open to young people of both genders from the age of 6 to 25.
