Corps as a training base mostly by Thurrock Sea Cadets but also by Sea Cadets from Essex, Greater London and Southern and Eastern areas between 1993 and 2014. The training available encompassed marine engineering, seamanship, canoeing, pulling, sailing, powerboating, cook/steward and instructors’ courses. Due to health and safety requirements plus the increasing costs to maintain the structural and internal integrity of the vessel Thurrock Sea Cadets were unable to keep her and in March 2015 the vessel was sold to a breakers yard at Erith on the River Thames.
