The Alacrity MV encountered fog and ran aground at Portheras Cove in Cornwall on 13 September 1963. The merchant vessel was on its way from Swansea to Brussels and carrying a cargo of coal when it ran into difficulty off the notoriously shipwrecked-prone Cornish coast. The vessel broke up over several weeks but stayed beached in the private cove until in 1981 when the army's Royal Engineers put a bomb under it.
