Port St Mary Lifeboat Station is located in the town of Port St Mary in the Isle of Man. It currently operates an All-weather Trent-class lifeboat, 14-26 Gough Ritchie II and a small D-class (IB1) inshore lifeboat, Frank Martin (D-873).

The Trent-class lifeboat is an all-weather lifeboat operated by the Royal National Lifeboat Institution (RNLI) from 30 stations around the coasts of Great Britain and Ireland to provide coverage up to 50 miles (80 km) out to sea. Introduced to service in 1994, the class is named after the River Trent, the second longest river wholly in England.
