Launch (boat)
Launch is a name given to several different types of boat. The wide range of usage of the name extends from utilitarian craft through to pleasure boats built to a very high standard.
In naval use, the launch was introduced as a ship's boat towards the end of the 17th century. On each warship, the launch was usually the largest boat out of those carried aboard. It could be propelled by oar or sail, with this type remaining in service into the 20th century. Steam launches were introduced on a trial basis in 1867, but as steam-powered ship's boats became more common, the majority were steam pinnaces.
Other military examples were the various motor launches used in the 20th century, employed for harbour defence, anti-submarine patrols, escorting coastal convoys, minesweeping and recovering aircrew from crashed aircraft. Generally these were decked boats, some of which were capable of fast speeds.
A powered boat operated by a regulatory or official organisation may be termed a launch – such as the police launch or a harbour-master's launch. The size, range and capabilities vary according to the precise role.
In private use, a launch is invariably a powered boat, using a steam, electric, petrol or diesel engine. Some are built to a very high standard of finish, with large amounts of varnished hardwood and polished fittings. Various local historic types are kept in use by enthusiasts and museums.
The word launch is derived from the Spanish lancha, which may be translated into English as "pinnace". It has been suggested that lancha is in turn derived from a Malay word Lancaran. The first instance of "launch" being used as a boat type in English was in 1697.
The launch steadily replaced the long-boat in the Royal Navy over the latter half of the 18th century. Both were usually the biggest boat carried by a warship or a merchant vessel in the age of sail. The transition from longboat to launch was influenced by the East India Company successfully experimenting with this change.
Launches were preferred as having greater carrying capacity, though they could be considered less seaworthy. One of two important roles was the carrying of drinking water. For example, a 33 ft (10 m) launch of 1804 could carry 14 large "leaguers" (barrels containing 150 imperial gallons (680 L) each), making a load of just over nine and half tonnes of water. A warship's launch would also be fitted with a windlass that allowed a ship's anchor to be carried or to be weighed (raised). This second essential role, generally for a ship's boat and specifically for the launch, was the laying out of anchors or weighing them after use. Before steam tugs were available, a ship's boat would often be used to kedge a ship out of a harbour or away from a hazard such as a lee shore, set a new anchor or inspect the cable if moored for a long time, among a range of "anchor work" tasks.
