On joining the Ramsey Steamship Company fleet she was the largest vessel within the fleet and brought the total number to five. "Ben Seyr" conveyed numerous types of cargo, with the mainstays being coal, grain and timber. With Captain Corlett in command, the "Ben Seyr" was approaching Ramsey Harbour on Friday, February 7, 1936, in challenging conditions. A southeasterly gale had developed making berthing in the port particularly difficult and leading to one of the "Ben Seyr's" ropes snapping following which she began to drift onto the Mooragh bank. Capt. Corlett displayed fine seamanship in raging control of the vessel and averting her grounding. In August 1937, one of the crew of the "Ben Seyr" was drowned in Maryport Harbour following an accident. Able Seaman Charles Kneale was 23 years old and came from Ramsey, Isle of Man. He was in a small boat sculling across the harbour together with another crew member Able Seaman Cecil Barber near to where the "Ben Seyr" was docked. In testimony Barber said that as they approached the dock gates Kneale fell into the water and although Barber did all he could to save him, he subsequently drowned. An inquest into Kneale's death was held later that night on board the "Ben Seyr" in order to allow the vessel to sail on the night tide. The "Ben Seyr" conveyed the body of Able Seaman Kneale back to Ramsey. "Ben Seyr" departed Ramsey on Sunday, 2 October 1938 under Captain Ambrose Crebbin, bound for Cardiff with a cargo of oats. During the course of the passage, she encountered heavy seas and was forced to run towards the Irish Coast in order to seek shelter, with word being received by her owners on the morning of Wednesday 5, that she had arrived off Rosslare, County Wexford. The Station Master at Rosslare reported that the "Ben Seyr" had departed at later that day resuming passage to Cardiff, after which nothing more was seen or heard from her. "Ben Seyr" was not equipped with a wireless and therefore no information was received regarding her position or the weather which she was encountering. By the following Tuesday, 11 October, with still no news of the "Ben Seyr," the following radio appeal was made on the BBC National Programme as well as on Raidió Teilifís Éireann. When Wednesday came with still no news of the "Ben Seyr" hope began to fade.
