HMS Raven was a Cruizer-class brig-sloop built by Perry, Wells and Green at Blackwall Yard and launched in 1804. Although she embodied some interesting innovations tailored for service in the area of the Straits of Gibraltar, she was wrecked before she got on station and never tested them. Her captain, the innovator, was the subject of a miscarriage of justice at his court martial for the loss of the ship from which his career never recovered.
