In December 1796, the
Navy Board placed new orders for four flush-decked sloops, to differing designs by the two Surveyors of the Navy — Sir
William Rule and Sir
John Henslow. In order to compare the qualities of ship-rigged and brig-rigged vessels, one vessel to each design was to be completed as a ship-sloop and the other as a brig-sloop. While the Henslow-designed vessels (the brig-sloop and the ship-sloop ) would see no further
sister ships built, the Rule-designed vessels (the brig-sloop
Cruizer and the ship-sloop ) would each have a single sister ship ordered in the following March, and Rule's
Cruizer design would subsequently see 106 constructed during the Napoleonic War. The hull design was exceeding fine (narrow as compared to length), with a noted deadrise amidships and a sharp sheer, giving away the design that had origins in the smaller
cutter-type designs. The order placed in March 1797 for the first sister ship to
Cruizer was quickly amended to compete the ship (
Osprey) as a ship sloop, but new orders for brig-sloops to the
Cruizer design were placed from 1802 up to 1813. A final order in 1815 (HMS
Samarang) was cancelled in 1820. The
Cruizer-class brig-sloops proved to be fast sailers and seaworthy, and the 32-pounder carronade armament gave them enormous short-range firepower, exceeding the nominal broadside of a standard 36-gun 18-pounder
frigate. To a Royal Navy increasingly desperate for manpower, the great attraction of the design was that — thanks to the two-masted rig and the use of carronades with their small gun crews — this firepower could be delivered by a crew only a third the size of a frigate's. The Dutch built three 18 gun-brigs —
Zwaluw,
Mercuur and
Kemphaan — to a similar design; in one case apparently a copy, though without the square tuck stern. The Russian brig
Olymp was also built to the same lines. The naval historian (and
novelist)
C.S. Forester commented in relation to the smaller
gun-brigs (brig-rigged vessels of under 200 tons) that The type was a necessary one but represented the inevitable unsatisfactory compromise when a vessel has to be designed to fight, to be seaworthy and to have a long endurance, all on a minimum displacement and at minimum expense. Few men in the Royal Navy had a good word to say for the gun-brigs, which rolled terribly and were greatly over-crowded, but they had to be employed. Later in the same book he was more complimentary as regards the larger brigs such as the
Cruizer class . Perhaps the most salient aspect of his statement is that the
Cruizer class and its smaller sister class, the
Cherokee class, highlight the huge expansion of the Royal Navy. Whatever else one may say of the class, the
Cruizer-class brig-sloops were both fast and provided serious firepower for minimal crewing, characteristics that appealed to a Navy suffering serious and ever increasing staffing shortages. The class proved to be ideal for many of the shallow water commitments in the Baltic and Ionian Seas, as well as around Danish waters. ==Manning==
