HMS Speedy (P296) was a Boeing Jetfoil, latterly a mine countermeasure vessel, of the British Royal Navy, based on the civilian Boeing 929 design. She was procured in 1979, as the first of a planned class of twelve, to provide the Royal Navy with practical experience in the operation of a hydrofoil, to ascertain technical and performance characteristics, and to oversee the capability of such a craft in the Fishery Protection Squadron and North Sea Squadron.[3][2] She was assigned to these squadrons in September 1981.[2] In 1982, she was used in minesweeping and minelaying trials at Portsmouth, but these were unsuccessful and she was sold into mercantile service in 1986.[4][2]
