The ensign of the Royal Harwich Yacht Club presented to Steam Yacht 'Fox' before F.L. McClintock's Franklin search expedition of 1857-1859. It takes the form of a blue ensign defaced in the fly with a yellow lion rampant. A rope and clip is attached to hoist the flag. The ensign is made of wool bunting with a linen hoist. It is hand sewn with the details of the rampant lion painted onto the fabric.

F.L. McClintock recalls the ensign in his book 'The Fate of Franklin' p. 10. 'Being desirous to retain for my vessel the privileges she previously enjoyed as a yacht, my wishes were very promptly gratified; in the first instance by the Royal Harwich Yacht Club, of which my officers and myself were enrolled as members — the Commodore, A. Arcedeckne, Esq., presenting my vessel with the handsome ensign and burgee of the Club...'
