Third in the series of Moonbeams owned by Charles Plumtree Johnson, she was initially intended as a fast cruiser, and William Fife had a free hand in designing her without regard for any racing rule. Johnson cruised her extensively in Scotland and in the South West of England before commissioning his largest and last Moonbeam. Sold to France, Moonbeam became famous as a racer both on the Atlantic and Mediterranean coasts.
By the 1980s, she was tired and in need of major work, which she received in Southampton. As part of this restoration, her original yawi rig was replaced by the current cutter rig.
