:''For brig-rigged sloops, see List of corvette and sloop classes of the Royal Navy'' :''For gunboats, see List of gunboat and gunvessel classes of the Royal Navy'' A gun-brig was a small brig-rigged warship that enjoyed popularity in the (British) Royal Navy during the Napoleonic Wars, during which large numbers were purchased or built. In general these were vessels of under 200 tons burthen, and thus smaller than the more common s or the even larger s. The gun-brigs generally carried 12 guns, comprising two long guns in the chase position and ten carronades on the broadsides. == Development == The earliest gun-brigs were shallow-draught vessels. Initially they were not brigs at all, but were classed as 'gunvessels' and carried a schooner or brigantine rig. They were re-rigged as brigs about 1796 and re-classed under the new term 'gun-brig'. They were designed as much to row as to sail, and carried their primary armament firing forward - a pair of long 18-pounders or 24-pounders, weapons which in any practical sense could only be trained and fired with the vessel under oars. The 1797 batch introduced means to improve their sailing ability. Each was fitted with a Schank drop keel,〔The Schank keel was invented by Captain (later Admiral) John Schank, and was known at the time as a "sliding keel". It was effectively a centreboard or daggerboard that the crew could raise to allow operations in shallow water under oars, or when sailing before the wind. In deeper water they could drop it to make the vessel weatherly when sailing to windward.〕 and lighter bow chasers replaced the heavy pair of guns firing forward over the bows; in later vessels one of the bow chasers would be moved aft to become a stern chaser, both of these guns then being mounted on the centreline and able to pivot. The broadside weapons consisted of 18-pounder carronades mounted on slides along both sides. The later gun-brigs developed from this beginning into smaller versions of the brig-sloops with increased draught and seaworthiness, but were less suited for inshore warfare. Compared with the flat-bottomed hulls of the 1794-1800 designs, by the time of the ''Confounder'' class the hulls had achieved a relatively sharp cross-section, as performance under sail had become a more important consideration than ease of rowing. By now they were clearly seen as small versions of the brig-sloop rather than enlarged gunboats. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of gun-brigs of the Royal Navy」の詳細全文を読む スポンサード リンク
