Bramble-class gunboat (1886)

The Bramble-class gunboat was a class of four gunboats mounting six 4-inch guns, built for the Royal Navy in 1886. In 1887 the first three were reclassified as gunvessels.[1]

This article is about the Royal Navy gunboat class of 1886. For the identically-named Royal Navy gunboat class of 1898, see Bramble-class gunboat (1898).

Design

The Bramble class was designed by William White. The ships were of composite construction, meaning that the iron keel, frames, stem and stern posts were of iron, while the hull was planked with timber. This had the advantage of allowing the vessels to be coppered, thus keeping marine growth under control, a problem that caused iron-hulled ships to be frequently docked. They were 165 feet (50 m) in length and displaced 715 tons.[1]

Propulsion

Triple-expansion steam engines built by Hawthorn Leslie (Rattler), North East Marine Engineering (Wasp) and Harland & Wolff (Lizard and Bramble) provided 1,000 indicated horsepower (750 kW) (Rattler 1,200 ihp (890 kW)) through a single screw, sufficient for 10 knots (19 km/h; 12 mph).[1]

Armament

Ships of the class were armed with six 4-inch 25-pounder quick-firing guns. Four machine guns were also fitted.[1]
