The Mumbles lifeboat disaster occurred in 1947 off south Wales when the Mumbles lifeboat was undertaking a rescue off Sker Point but was overwhelmed by the sea with the loss of all eight lives in the lifeboat.
On 23 April 1947 the SS Samtampa en route from Middlesbrough to Newport decided to stop at Sker Point on the Glamorgan coast not far from Porthcawl. Its three anchor cables were unable to hold the ship in the gale raging at the time and the ship foundered on the rocks, breaking into three.
The Mumbles lifeboat, in attempting a rescue, was believed to have been overwhelmed by a freak wave and all the crew were drowned. Memorials to the crew stand in the churchyard of All Saints' Church, Oystermouth.
