Vanguard class ship of the line

The sixth HMS Vanguard, of the British Royal Navy was a 78 gun (or 80 gun) second rate ship of the line, launched on 25 August 1835 at Pembroke Yard. to the directions of the Surveyor, Captain Sir William Symonds. The Vanguard was the first of a class of eleven. She was ordered from Pembroke Yard in June 1832; HMS Collingwood was ordered 'as a duplicate frame using the moulds of Vanguard, to test the efficacy of an American scheme whereby duplicate frames were stored for many years.' Vanguard was laid down in May 1833; she required 60 skilled men for 16 weeks to set up the frame. She was launched on schedule in August 1835. 'Vanguard cost £56,983 to build, and a further £20,756 to fit for sea.' Her construction used 3,560 loads of timber and required 186 man years.

Warships designed to the ideas of Captain Sir William Symonds (1782–1856) are known as Symondite warships, although the adjective has no official use as terminology. His intention was to give the Royal Navy an advantage in speed (under certain weather conditions), allowing it to force action. Symondite warships were very broad, and had a sharp V shaped hull form. (Preceding designs had a U shaped hull form.) Their wide beam gave them very high stability, which allowed them to carry nearly twice the power of sail as vessels of the old type. Unfortunately the Surveyor's department was understaffed, with the result that their stability was over done. Symondite warships rolled quickly, heavily and sometimes unevenly. This made them poor gun platforms. The rapid rolling also caused the rigging to wear out more quickly than on previous designs. Because Symondite warships got their stability from their great beam, they did not need to carry so much iron ballast as previous designs. They had higher and wider gun decks than preceding designs. This gave the gun crews more space to work in, improving efficiency. It also helped their sailing performance, because they were carrying fewer guns for their size. Symondite warships were very sensitive to how they were stowed. If trimmed carefully, they were fast in moderate winds, thought they did not do as well as preceding designs in head seas, or rough seas. Compared with previous designs, Symondite warships required 19% more loads of wood and 30% more man hours to build. Some of the Symondite warships were converted to steam in the 1850s (though not Vanguard). Their V shaped hull made it difficult to add a steam engine and boilers and to store coal. The extra weight was low in the ship, exacerbating their excess stability, which made their rolling even worse than before. (In fairness, at the time they were designed, it was never anticipated that they would be converted to steam.)

Vanguard was commissioned in 1837 by Captain Sir Thomas Fellowes, with the normal picked complement of officers, including Baldwin Walker as First Lieutenant and Mr Miller, one of Symonds's favourite sailing masters. The object was clear. Symonds wanted his ships to be tried by men capable of making the best of their qualities Out in the Mediterranean Vanguard soon made a name for herself as the fastest ship in the fleet, with the handiness of a frigate when beat out of Grand Harbour [Malta].' On the night of 30 January 1838, Vanguard was at Malta under the command of Captain Sir Thomas Fellowes. The ship's First Lieutenant, C. M. M. Wright, ordered the Assistant Surgeon, Robert Thomas Charles Scott, to stomach pump a drunken seaman. Scott expressed the medical opinion that a stomach pump should not be administered. Wright ordered him to give it anyway as a punishment and reminded Scott that it was an order he had received. A short while later Wright ordered Scott to do the same to another seaman. The next morning Scott reported the matter to Commander Baldwin Walker who reported Scott to the Captain for disrespect and disobedience of a lawful order. Captain Fellowes threatened Scott with a court martial and reported him to Sir William Burnett, the Physician General of the Navy. When this affair became public knowledge, an Admiralty Order was issued banning the use of a stomach pump as a punishment. Captain David Dunn commanded Vanguard from 2 April 1843 to August 1843. Vanguard again served in the Mediterranean (including operations on the coast of Syria in 1840), and off Lisbon. In October 1843 Vanguard was out of commission at Devonport. On 4 February 1845, Vanguard was commissioned by Captain George Wickens Willes, and served in the Channel Squadron, the 1845 and 1846 Evolutionary Squadrons, and in Mediterranean.) and her sister Superb (Captain Anwar Lowry Corry) were the slowest battleships in the squadron. The Surveyor (Symonds) thought that they had been badly stowed and needed recoppering. Once this was done they performed well. Vanguard was refitted after the 1845 trials (as were Superb and Canopus). In the August 1846 trials, Vanguard and Canopus were 'nearly alike in performance, with the former superior in smooth water, and the latter in rough.' (The significance of Canopus is that she was regarded as one of the best of the previous type of 84 gun two deckers.) In May 1846 Evolutionary Squadron exercised firing the stern batteries. This was a rare occurrence and reflects no credit on any of the two deckers:
Vanguard took ten minutes to clear for action and then fired two rounds from each stern gun. However the extreme overhang of the stern prevented the muzzles running clear, with the result that there was a minor fire. Superb took 15 minutes to clear for action plus an hour to remove her sashes, and then was able to fire without incident. Canopus was excused firing altogether. commanded Vanguard in the Mediterranean from 6 November 1847 until Vanguard paid off in March 1849. Vanguard's last commission was as Coast Guard at Kingston from 18 February 1861 to March 1862, commanded by Commanded by Captain Edmund Heathcote. Vanguard was renamed Ajax in 1867, to allow her former name to be given to an ironclad battleship then being laid down in the ways. Ajax (ex Vanguard) was broken up in 1875.
