The Marchioness disaster was a collision between two vessels on the River Thames in London in the early hours of 20 August 1989, which resulted in the deaths of 51 people. The pleasure boat Marchioness sank after being hit twice by the dredger Bowbelle at about 1:46 am, between Cannon Street railway bridge and Southwark Bridge.
