Text of statute as originally enacted

The Longitude Act 1714 (13 Ann. c. 14), also known as the Discovery of Longitude at Sea Act 1713, was an act of Parliament of Great Britain passed in July 1714 at the end of the reign of Queen Anne. It established the Board of Longitude and offered monetary rewards (Longitude rewards) for anyone who could find a simple and practical method for the precise determination of a ship's longitude. The act of 1714 was followed by a series of other Longitude Acts that revised or replaced the original.
