HMS Plumpton was a of the British Royal Navy. She served in the First World War and was of a paddle wheel design. She struggled in heavy seas. Plumpton was mined on 19 October 1918 off Ostend. The ship was beached on the Belgian coast and was broken up where she lay.
The design was developed during the First World War after the earlier success of converted paddle wheel ships. The vessel was propelled by a paddle wheel powered by diagonal compound engine fed steam by cylindrical boilers rated at 1500lk=inNaNlk=in. A Racecourse-class minesweeper was capable of storing 156LT of coal to use as fuel. The Racecourse-class minesweepers were 245feet long overall with a standard beam of 29feet and was 58feet including paddles. The vessel had a draught of 7feet and had a standard displacement of 810LT. Racecourse-class minesweepers were armed with two 6-pounder (57mm) guns and two 2-pounder (40mm) guns.
Plumpton was ordered as part of the first group of Racecourse-class minesweepers in September 1915. The ship was constructed by McMillan at their shipyard in Dumbarton, Scotland with the yard number 465 and launched on 20 March 1916. In keeping with the class, the ship was named for the racecourse in Plumpton, East Sussex and construction was completed in June 1916.
Plumpton was attached to the Grand Fleet on completion, being part of the 3rd Minesweeping Flotilla, which was equipped with Racecourse-class ships.[1] The ship was still a member of the 3rd Minesweeping Flotilla in June 1917,[2] but had transferred to the Dover Patrol the next month.[3]
The minesweeper struck a naval mine off the coast of Ostend, Belgium on 19 October 1918. Plumpton was beached on the coast to prevent the ship from sinking. Plumpton was broken up for scrap at the site where she was beached.
