The adjoining Havengore Creek marked the northern end of the PLA's jurisdiction prior to 1964, when it was extended to include the whole of the Thames Estuary.

The National Physical Laboratory helped design and test her twin counter-rotating propellers and underwater fittings, while Decca Radar oversaw trials of her survey systems.

Changing hands again in 2006, three further phases of restoration - including the reuse of parts from a 0-4-0 diesel locomotive - have ensured that she remains fully operational in compliance with MCA regulations, while respecting her historic fabric.

Moored at St Katharine Docks, Havengore currently undertakes a mixed programme of public service and charitable events and is also available for corporate hospitality purposes.

On her journey along the Thames, Havengore was saluted by a flypast of 16 English Electric Lightning fighter jets, and dock cranes were bowed as she passed.

On 17 May 2012 it was announced that the Havengore had been selected to carry members of the Royal Family as part of Queen Elizabeth II's Diamond Jubilee celebrations in a flotilla of over a thousand vessels during the Thames pageant on 3 June 2012.
