SS Cushag was sold once more, this time to a London broker, from whom she was purchased by the Isle of Man Steam Packet Company in May 1920, at a cost of £22,000 (equivalent to £). Small and drawing so little water, she was mostly used for cargo trade in the Island's smaller ports - Port St Mary, Peel, Laxey and Castletown. After over 20 years service with the Company, she was sold to London agents in January 1943, and then went on to Stornoway on the Isle of Lewis for four years. She transferred to Kirkwall in Orkney in 1947. "Cushag"
Port St Mary St Mary's is the Port St Mary site of the Living Hope Community Church (formerly known as Port St Mary Baptist Church). The current church building was built in the early 2000s on the site of the former Port St Mary Wesleyan Methodist Chapel, which was completed in 1895, closed in 1970 and was demolished in 2000. In the lower part of the village, near the port, lies the current Port St Mary Methodist Chapel, built in 1903 as a Primitive Methodist chapel and known as Mount Tabor. Another smaller former Wesleyan chapel, on the High Street, opened in 1835
