Gunboats were used by all combatants in the Napoleonic Wars. They were cheap and easy to produce and, although small, were armed with at least one heavy gun. Gunboats were used mainly in coastal waters where their ability to move under oars alone made them a potent weapon, especially against ships that were becalmed. Sizes ranged from around 40ft to slightly over 80ft. Their armament also varied from one long gun, possibly as small as a 12-pounder up to perhaps eight long guns and carronades. Most popular were 18- and 24-pounders. Sail plans were also diverse, the spritsail and lateen sail being among the most common.

The British gunboat kit comprises hull, gaff sail and jib, mast, bowsprit, tiller, companion way, short 24-pounder and slide, and a 32-pounder carronade. There are a few crew figures as well. Sails are photo-etched brass; all other fittings are in white metal.
