The Shambles Lightship was on station between 1859 and 1976.  it marked the Eastern end of the Shambles Shoal in position 50°36’50” North, 002°19’90” West, about 5 miles to the East of Portland Bill.

Earlier this year Trinity House announced that the Channel Lightvessel will be permanently withdrawn in August 2021 and so there will be one fewer lightship in the Radio 4 forecast.
