The Leda-class frigates, were a successful class of forty-seven British Royal Navy 38-gun sailing frigates.

Origins[edit]

The design of the name ship, Leda of 1800, was based on the Sané-designed Hébé.[1] Hebe was a French Hébé class frigate that the British 44-gun fifth rate HMS Rainbow captured in 1782. (The British took Hébé into service as HMS Hebe but in 1805 renamed her HMS Blonde). The class of frigates built to the lines of the Leda were in contemporary parlance called the 'Repeat Leda class'.[2]

Pomone, the first ship of the class, was built using Josiah Brindley's patent method of construction which dispensed with wooden 'lodging' and 'hanging knees', oak elements which had to be grown to shape, using instead iron fastenings and iron knees. Oak suitable for shipbuilding had become increasingly difficult to obtain through the long period of warfare.[3]

Characteristics and performance[edit]

The vessels of the class were fast, most recording 13kts large and 10kts close-hauled. However, their French-style proportions made them unweatherly compared to frigates designed to British proportions (such as the Lively class). Many captains requested additions to the false keel of these frigates to remedy this. The Leda-class stood to their canvas well and liked a stiff gale, but were prone to excessive pitching in very heavy seas. All captains complained of the class's poor stowage capacity, the result of their fine French underwater lines, but stowage improved after the introduction of iron fresh-water tanks. The class was also reckoned to be "wet", a result of a tendency to work their seams due to lively rolling and pitching.[4]

Ships of the class[edit]

HMS Pomone.

The name Leda was taken from Greek mythology, as was common at the time; the Greek Leda was a woman whom Zeus seduced while he was masquerading as a swan. After Leda, the Admiralty had no more ships to this design for several years. Then with the resumption of war with France either looming or under way, the Admiralty ordered eight further ships to this design in 1802-09:

In 1812 the Admiralty ordered eight ships to be built of "fir" (actually, of red pine) instead of oak; these were sometimes called the Cydnus class:

The Admiralty ordered seven more vessels to this design in 1812-15, with those constructed in Britain reverting to oak and those constructed in Bombay using teak:

The Admiralty ordered another six vessels in 1816, but of a modified design that incorporated Sir Robert Seppings's circular stern and "small-timber" form of construction:

A further twenty-three ships were ordered to this modified design in 1817, although the last six were never completed, or not completed to this design:

The last six ships of the 1817 orders were never completed to this design:

  • HMS Pegasus - canceled 1831
  • HMS Nemesis - re-ordered to Seringapatam-class design.
  • HMS Statira - re-ordered to Seringapatam-class design.
  • HMS Jason - re-ordered to Seringapatam-class design.
  • HMS Druid - re-ordered to Seringapatam-class design.
  • HMS Medusa - canceled 1831
