Harbour training ship

In 1972, Eastbourne replaced as the 'afloat' training ship for the artificer apprentices at HMS Caledonia. During their 14 weeks aboard ship, the apprentices were trained in general engineering and were examined for their auxiliary machinery certificates. In 1977, a hull inspection found that Eastbourne was no longer fit for sea, though her machinery was still in good condition. Her propellers were removed, and 'brake wheels' were fitted as a replacement. This enabled her to be steamed at full power with no forward movement. This enabled the apprentices to assist in operation of her machinery at full power, with the added benefit of churning the dockyard basin water up to improve its aeration.
