"The early steam battleships, such as the "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 and the "Bulwark" to . 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."
