Motor Launch ML-286 is a First World War submarine chaser built by Elco, that saw action with Royal Navy.

It is currently in a very poor condition and lies on the banks of the River Thames at Isleworth Ait.

They served between 1916 and the end of the war with the Royal Navy defending the British coast from German submarines.

She was requisitioned for service as an auxiliary patrol vessel in the Thames but found to be unsuitable, and later was returned to her owners in August 1940.

It is being monitored and recorded by volunteer members of the Thames Discovery Programme (TDP) based at Museum of London Archaeology (MOLA).
