Duncan-class ship of the line (1859)

The Duncan class of 101-gun two-decker steam line-of-battle ships are considered by Professor Andrew Lambert to have been the "final statement of the British design progress" for steam two-deckers. The class consisted of HMS Duncan and HMS Gibraltar. The Bulwark class had identical hulls. HMS Gibraltar was the last wooden steam line-of-battleship to commission as a private ship in the Royal Navy.

Design
The first British steam 101-gun two-decker was the St Jean d'Acre, which was ordered and laid down in 1851 and was "the first ship that can be directly attributed to Sir Baldwin Walker's influence. [She was] an expansion of the Agamemnon [91-guns], her superior qualities were developed in the succeeding Conqueror and Duncan classes of 101-gun ships." The Duncan class were longer and broader versions of the Conqueror, which was a success as they were noticeably faster (see table below).

"The early steam battleships, such as the 230 ft Agamemnon, combined a measure of speed under sail or steam with similar manoeuvring powers to the sailing ships. This persuaded Walker to try even longer hulls, the Renown being drawn out to 244 ft and the Bulwark  to 252 ft.  While the post-war ships, from their greater length and finer lines, reached higher speeds they did so at the expense of the facility and precision of their response to the helm.  New ships such as the Donegal, 101 and Renown, 91 were considered slow in their stays.  This lack of handiness was emphasised by their operating in company with older ships such the St Jean d'Acre, 101 and James Watt, 91 which lacked speed, but tacked and wore far more easily. Lord Aukland had anticipated this problem in 1847. "

Duncan and Gibraltar "presented a very different appearance from the Baroque splendour of the early Eighteenth Century, with their regular outline bereft of almost all embellishment beyond the elliptical stern gallery and the figurehead and painted in the severe black and white bands of the era. These were the most striking and intimidating of all wooden warships, replacing elegance with majesty.  As such they were fitting precursors for the industrial architecture of the iron-clads."

** Note that Gibraltar's trial speed was undertaken without masts or stores.
