While the Henslow-designed vessels (the brig-sloop Busy and the ship-sloop Echo) would see no further sister ships built, the Rule-designed vessels (the brig-sloop Cruizer and the ship-sloop Snake) 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.

[1] 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.

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.

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.

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.

Prior to 1808, the complement of officers, men, and boys for a Cruizer-class brig-sloop included 15 Royal Marines.

The crew sizes were disproportionate at 175 to 120, and at least some of the Cruizer class in these combats were outfitted with 24-pounder carronades vice the normal 32-pounders.

[6] USS Wasp, in another combat, would retain control despite the loss of her gaff, main topmast, and the mizzen topgallant.

Building of fir (pine) made for speedier construction at the cost of reduced durability in service.
