The Britomart class was an improved version of the Dapper class designed by W.H. Walker, and as such comes under the generic group "Crimean gunboats" although this class was ordered and built long after the end of the Crimean War. These were the last Royal Navy gunboats to have wooden hulls: subsequent gunboats were of composite construction, with wooden planking over iron frames.[1]
Propulsion
The class were fitted with a single-cylinder single-expansion reciprocating steam engine. The engines for Britomart and Cockatrice were by John Penn and Sons; the engine builders for the other ships are not recorded. The single screw could be hoisted to give improved performance under sail.[1]
Sail plan
The ships were provided with a three-masted barquentine rig, that is, with square sails on the foremast and fore-and-aft sails on the main and mizzen masts.[1]
