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. [1] 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. The first instance of "launch" being used as a boat type in English was in 1697. [2] : 168
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. [3] : 41–43
Launches were preferred as having greater carrying capacity, though they could be considered less seaworthy. An important role was the carrying of drinking water. For example, a 33 foot 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). 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 before steam tugs were available to move sailing vessels. [3] : 41–43
The launches issued to naval ships varied in size depending on the size of the ship they equipped. An 1815 schedule of ship's boats showed the range of 15 different lengths for launches from 34 feet (for a ship of 100 guns) down to 16 feet for a 200 ton sloop. As steam power became common in the navy, the need to transport drinking water (which could be distilled in the engine room) and transport anchors and cables to move a sailing ship both disappeared. By the last quarter of the 19th century, launches were only issued in one length, 42 feet. [3] : 62, 71
Launches had double-banked oars [lower-alpha 1] The usual sailing rig for much of the 19th century was a two-masted ketch rig. A schooner rig was in use from 1878 and the de Horsey sloop rig was adopted from 1884. [3] : 91–97
During the Demak Sultanate attack on Portuguese Malacca of 1513, lancaran were used as armed troop transports for landing alongside penjajap and kelulus, as the Javanese junks were too large to approach shore. [4]
In 1788 Captain William Bligh and 18 crewmen were set adrift by mutineers in Bounty’s 23-foot launch. Bligh navigated the open boat more than 4000 miles, losing only one man – Tonga to Timor, 3,618 nmi (6,701 km; 4,164 mi). [5]
On the River Thames the term "launch" is used to mean any motorised pleasure boat. The usage arises from the legislation [6] governing the management of the Thames and laying down the categories of boats and the tolls for which they were liable.
Motor Launch was the designation for a type of vessel used in World War II by the Royal Navy and some other navies[ citation needed ] for inshore work defending the coast from submarines. They were typically 60-to-115-foot or 18-to-35-metre long and carried relatively light armament – a few depth charges, a gun and a few machine guns.
In competitive rowing the term "launch" is used to refer to any motorized boat used by the coach to follow practicing boats during workouts. [7]
A yawl is a type of boat. The term has several meanings. It can apply to the rig, to the hull type or to the use which the vessel is put.
A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
The Bermuda sloop is a historical type of fore-and-aft rigged single-masted sailing vessel developed on the islands of Bermuda in the 17th century. Such vessels originally had gaff rigs with quadrilateral sails, but evolved to use the Bermuda rig with triangular sails. Although the Bermuda sloop is often described as a development of the narrower-beamed Jamaica sloop, which dates from the 1670s, the high, raked masts and triangular sails of the Bermuda rig are rooted in a tradition of Bermudian boat design dating from the earliest decades of the 17th century. It is distinguished from other vessels with the triangular Bermuda rig, which may have multiple masts or may not have evolved in hull form from the traditional designs.
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
A longboat is a type of ship's boat that was in use from circa 1500 or before. Though the Royal Navy replaced longboats with launches from 1780, examples can be found in merchant ships after that date. The longboat was usually the largest boat carried. In the early period of use, a ship's longboat was often so large that it could not be carried on board, and was instead towed. For instance, a survey of 1618 of Royal Navy ship's boats listed a 52 ft 4 in longboat used by the First Rate Prince, a ship whose length of keel was 115 ft. This could lead to the longboat being lost in adverse weather. By the middle of the 17th century it became increasingly more common to carry the longboat on board, though not universally. In 1697 some British ships in chase of a French squadron cut adrift the longboats they were towing in an attempt to increase their speed and engage with the enemy.
Steam frigates and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. There were some exceptions like for example the French Napoléon class steam ship of the line was meant to stand in the line of battle, making it the world's first steam battleship. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of steam-powered versions of the traditional ships of the line, frigates, corvettes, sloops and gunboats.
A cutter is a name for various types of watercraft. It can apply to the rig of a sailing vessel, to a governmental enforcement agency vessel, to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships.
The rating system of the Royal Navy and its predecessors was used by the Royal Navy between the beginning of the 17th century and the middle of the 19th century to categorise sailing warships, initially classing them according to their assigned complement of men, and later according to the number of their carriage-mounted guns. The rating system of the Royal Navy formally came to an end in the late 19th century by declaration of the Admiralty. The main cause behind this declaration focused on new types of gun, the introduction of steam propulsion and the use of iron and steel armour which made rating ships by the number of guns obsolete.
The full-rigged pinnace was the larger of two types of vessel called a pinnace in use from the sixteenth century.
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water. Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".
A gig is a type of boat optimised for speed under oar, but usually also fitted with a sailing rig for appropriate conditions. The type was in use by Deal boatmen in the 18th century. It first occurred as a naval ship's boat after Deal boatbuilders recommended a different design to boats ordered from them by the Royal Navy to equip the cutters purchased in the 1760s to combat smuggling. The captains of larger warships soon sought permission to substitute a gig for one of the heavier boats which were then used; some even had a gig built at their own expense. The gig therefore became part of the usual complement of ship's boats used in warships.
A hoy is a small sloop-rigged coasting ship or a heavy barge used for freight, usually with a burthen of about 60 tons (bm). The word derives from the Middle Dutch hoey. In 1495, one of the Paston Letters included the phrase, An hoye of Dorderycht, in such a way as to indicate that such contact was then no more than mildly unusual. The English term was first used on the Dutch Heude-ships that entered service with the Royal Navy.
As a ship's boat, the pinnace is a light boat, propelled by oars or sails, carried aboard merchant and war vessels in the Age of Sail to serve as a tender. The pinnace was usually rowed but could be rigged with a sail for use in favorable winds. A pinnace would ferry passengers and mail, communicate between vessels, scout to sound anchorages, convey water and provisions, or carry armed sailors for boarding expeditions. The Spanish favored them as lightweight smuggling vessels while the Dutch used them as raiders. In modern parlance, "pinnace" has come to mean an auxiliary vessel that does not fit under the "launch" or "lifeboat" definitions.
A ship's boat is a utility boat carried by a larger vessel. Ship's boats have always provided communication with the shore and with other ships. Other work done by such boats has varied over time, as marine technology has changed. In the age of sail, especially for warships, an important role was the collection of drinking water. A large enough boat may be needed to carry an anchor to some distance away from the ship, so as to kedge out of a harbour or away from a hazard - and also to recover such an anchor afterwards. Warships have always used their boats as an extension to their military role. This includes the provision of a means of escape for the crews of fireships, the landing of troops, or the "cutting out" raids that were used by the Royal Navy, especially during the Napoleonic Wars. All these requirements competed with the need to be able to stow the boats on board in a way that did not interfere with the normal operation of the ship.
Rose Hill Packet, was a marine craft built in Australia to serve the second place of European settlement in Australia, "Rose Hill", the furthest navigable point inland on the Parramatta River. When launched the vessel was named Prince William but was later named the Rosehill Packet by the convicts. The boat design was later called a packet boat, because its use was that of running the first Parramatta River trade ferry, passenger, cargo, and mail service between the Sydney Cove and the Rose Hill (Parramatta) First Fleet settlements after she was launched in Sydney Cove in September and commissioned on 5 October 1789. She was the first purpose-built sailing vessel constructed in Australia. She later earned the nickname 'The Lump'. Some authorities believe that a 1790 drawing by First Fleet MIdshipman George Raper shows the vessel in the centre of Sydney Cove.

This glossary defines the various types of ships and accessory watercraft that have been used in service of the United States. Such service is mainly defined as military vessels used in the United States Navy and United States Coast Guard, as well as the defunct, incorporated, or renamed institutions such as the United States Revenue Cutter Service. Service of the United States can also be defined in this context as special government missions in the form of expeditions, such as the Wilkes Expedition or the North Pacific Exploring and Surveying Expedition. The scope of the glossary encompasses both the "Old Navy" of the United States, from its beginnings as the "Continental Navy", through the "New Navy" and up to modern day. The watercraft included in the glossary are derived from United States ships with logbooks published by the National Archives and Records Administration.
