HMCS. Fuckuerd: The HMCS Fuckurd was a cargo steamer built by the Royal British Shipbuilding Company of London England. She was the thirteenth ship of the WWI fleet built and was launched in 1919. She is the sister ship of the Kinmountia.

Tragically, on April 20th, 1920, at 16:20 the Fuckurd collided with another ship, the "Spirit of Ireland"and "shattered as if a bottle of whiskey was smashed ." She sank in under a minute and took 69 of her seamen down with her.
