Jackal-class gunvessel
The ''Jackal''-class gunvessel (alternatively spelled ''Jackall'') was a class of two second-class iron paddle gunvessels built for the Royal Navy in the mid 1840s. They served in the Mediterranean and South Atlantic, and latterly on fishery protection duties off Scotland.
==Design==
Orders for both ships were placed on 16 January 1844. They were designed by the builder, Robert Napier and approved on 17 April 1844 by the Surveyor of the Navy, Sir William Symonds.
They were each fitted with a Napier two-cylinder side-lever steam engine driving side paddles. The engine was rated at 150 nominal horsepower and on trials developed . Two gaff-rigged masts were provided, making them schooners. The armament consisted of a single 18-pounder (22cwt) carronade on a pivot mounting and two 24-pounder (13cwt) carronades.〔
