[AUSTRALIA-NSW] Broken Bay Surveyed by Captain F.W.Sidney.

Mapmaker:

The Admiralty’s first Hydrographer, Alexander Dalrymple, was appointed in 1795 and in the next year the existing charts were brought together and catalogued. The first chart the Admiralty produced was of Quiberon Bay in Brittany and did not appear until 1800. Dalrymple was succeeded in 1808 by Captain Thomas Hurd, under whose stewardship the department was given permission to sell charts to the public. Hurd oversaw the first production of “Sailing Directions” in 1829 and the first catalogue in 1825 with 736 charts. Rear-Admiral Sir W. Edward Parry was appointed Hydrographer in 1823 after his second expedition to discover a Northwest Passage. 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 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.
