Hydrographer of the Navy is a Royal Naval appointment. From 1795 until 2001 the post was responsible for the production of charts for the Royal Navy, and around this post grew the United Kingdom Hydrographic Office. In 2001 the post was disassociated from UKHO, and the Hydrographer of the Navy is now a title bestowed upon the current Captain (Hydrography and Meteorology) on the staff of Commodore Devonport Flotilla.
Before the establishment of the post, captains of Royal Navy ships were responsible for the provision of their own charts. In practice this meant that ships often sailed with inadequate information for safe navigation, and that when new areas were surveyed, the data rarely reached all those who needed it. The Admiralty appointed Alexander Dalrymple as Hydrographer in 1795, with a remit to gather and distribute charts to HM Ships. Within a year existing charts had been collated, and the first catalogue published. It was 5 years before the first chart (of Quiberon Bay in Brittany) was produced by the Hydrographer.
Under Dalrymple's successor, Captain Thomas Hurd, Admiralty charts were sold to the general public, and by 1825 there were 736 charts listed in the catalogue. In 1829 the first sailing directions were published, and in 1833, under Rear-Admiral Sir Francis Beaufort (of the eponymous Beaufort scale) the tide tables were first published. Notices to Mariners came out in 1834, allowing for the timely correction of charts already in use. Beaufort was certainly responsible for a step change in output; by the time he left the office in 1855 the Hydrographic Office had a catalogue of nearly 2,000 charts and was producing over 130,000 charts, of which about half were provided to the Royal Navy and half sold.
In 1939, on the outbreak of World War II, the Hydrographic Office moved to Taunton, and the post of Hydrographer moved with it. In 2001 a chief executive was appointed to run the United Kingdom Hydrographic Office as a profit-making agency of the British Government, and at this time the roles of National Hydrographer and Hydrographer of the Navy were divided. The title of Hydrographer devolved to Captain(HM),[Note 1] a senior officer on the staff of the Commodore of the Devonport Flotilla, and the senior Royal Navy officer within the HM branch. As of 2010 the post has been renamed Captain(HM Ops), but continues to carry the title Hydrographer of the Navy.
