SS Samtampa was a 7,219 ton steamship wrecked on Sker Point, off Porthcawl and Kenfig, Wales, in the Bristol Channel on 23 April 1947.

[3] Sent to Britain under the Lend-Lease program, the ship was renamed, and managed by the Houlder Line on behalf of the Ministry of War Transport.

An oil spill from the tanks of the wrecked ship created an area of calm water, which the lifeboat coxswain, William Gammon (previously a winner of the RNLI Gold Medal), attempted to use to their advantage to enable them to pull alongside, and those who died were choked by the oil rather than drowning.

A memorial to the victims of the Samtampa tragedy is in Porthcawl Cemetery and a commemorative plaque can be found marking the "final resting place of The Mumbles lifeboat" at Sker Point.

On Sunday 23 April 2022, Porthcawl Runners hosted a 75th anniversary fun run on Mumbles Seafront.
