Only one voyage ended the story of Manes P MV Manes P had originally been built as Escalante for Royal Mail Lines at Harland and Wolff’s Govan yard. She was launched on July 5, 1955 and delivered on December 14 that same year as a general cargo ship, at times also carrying up to 12 passengers. Her recorded size was 7,791 gross tons, with an overall length of about 444.5 feet, a beam of about 58 feet, a single screw, and a 4,500 bhp diesel engine that gave her a speed of around 13.5 to 14 knots. In January 1970 she was sold to Marescencia Compañia de Navegación SA, renamed Manes P, and entered service for her new owners.
Her career under that new name lasted only a single voyage. On a ballast trip from the Tyne to Saint John, New Brunswick, she ran onto the rocks on the south side of Partridge Island in heavy weather during the night of February 2 to 3, 1970. Sources differ slightly on the exact date because the grounding happened overnight, but they agree that she was lost on her first voyage as Manes P. Attempts to refloat her failed, and she was later marked for breaking up and sold for scrap. Parts of her hull were still being reported visible at low tide off Saint John many years later, including as recently as 2020.
