HMS Portisham was one of 93 ships of the Ham-class of inshore minesweepers.

Their names were all chosen from villages ending in -ham. The minesweeper was named after [Portesham] in Dorset. The spelling PORTISHAM is probably a legacy from the previous vessel of this name in service during WW2 and is spelt thus in all authoritative reference books.

After her sale in 1989 she was laid up and for sale in a boatyard in Essex. She was procured for conversion to a liveaboard ship by an Irish national in 2007 and is currently the second biggest private vessel under Irish Flag. Her home port is Balbriggan, Co Dublin. Under threat from Fingal County Council, who have lied on several counts in order to get a court order, initially, to have her removed and broken up, now to have the owner removed and the boat moved into storage. The owner doesn't believe that the state even has the authority to take possession of a vessel under these circumstances (unauthorised development under the Planning and Development act). That, along with the fact that she is the owner's home, means that he is defying the court order, and the county council, and is prepared to repel boarders by whatever means he feels is necessary.

Portisham is currently berthed in Balbriggan, Co Dublin after total replacement of her propulsion machinery and a successful voyage from Pembroke Dock. Many thanks to the management of Pembroke Port for their faith and patience in allowing her to remain there for so long.
