An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The skeg also acts as a rudder when the engine is not running. Unlike inboard motors, outboard motors can be easily removed for storage or repairs.
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina.
An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas. For smaller boats, the floor and hull are often flexible, while for boats longer than 3 metres (9.8 ft), the floor typically consists of three to five rigid plywood or aluminium sheets fixed between the tubes, but not joined rigidly together. Often the transom is rigid, providing a location and structure for mounting an outboard motor.
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States.
A motorboat, speedboat or powerboat is a boat that is exclusively powered by an engine.
The Landing Craft, Tank (LCT) was an amphibious assault craft for landing tanks on beachheads. They were initially developed by the Royal Navy and later by the United States Navy during World War II in a series of versions. Initially known as the "tank landing craft" (TLC) by the British, they later adopted the U.S. nomenclature "landing craft, tank" (LCT). The United States continued to build LCTs post-war, and used them under different designations in the Korean and Vietnam Wars.
A Landing Craft Utility (LCU) is a type of boat used by amphibious forces to transport equipment and troops to the shore. They are capable of transporting tracked or wheeled vehicles and troops from amphibious assault ships to beachheads or piers.
Landing Craft Assault (LCA) was a landing craft used extensively in World War II. Its primary purpose was to ferry troops from transport ships to attack enemy-held shores. The craft derived from a prototype designed by John I. Thornycroft Ltd. of Woolston, Hampshire, UK. During the war it was manufactured throughout the United Kingdom in places as various as small boatyards and furniture manufacturers.
Inflatable Rescue Boats (IRBs) are rubber boats with an outboard motor used in surf lifesaving. IRBs have been used for all forms of surf rescue, retrieval, and service by Surf Lifesaving in New Zealand, Australia, and Del Mar, California since the late 1980s.
An inboard motor is a marine propulsion system for boats. As opposed to an outboard motor where an engine is mounted outside the hull of the craft, an inboard motor is an engine enclosed within the hull of the boat, usually connected to a propulsion screw by a driveshaft.
The word Drascombe is a trademark that was first registered by John Watkinson who applied it to a series of sailing boats which he designed and built in the period 1965–79 and sold in the United Kingdom (UK). They comprised the Coaster, Cruiser Longboat, Dabber, Drifter, Driver, Gig, Launch, Longboat, Lugger, Peterboat, Scaffie, Scaith and Skiff, together with a few other one-offs. They have wide and deep cockpits, adaptable boomless rigs and high bulwarks.
The Hirondelle is a fibreglass cruising catamaran, 23 feet (7.0 m) in length, with a beam of 10 feet (3.0 m), and in its standard configuration has 4 or 5 berths. Based on Chris Hammond's 20 ft (6.1 m) 'Meon' cold-moulded/sheet-plywood catamaran of 1967–8, the original design was bought by Brian Carvill in 1969, modified, renamed Hirondelle, and manufactured in fibreglass by Robert Ives Boatbuilders in Christchurch, England.
An amphibious warfare ship is an amphibious vehicle warship employed to land and support ground forces, such as marines, on enemy territory during an amphibious assault.
The Cedric class, formerly known as Arrow class, is a series of fast patrol/assault speed boats constructed by the Sri Lanka Navy for use by its littoral warfare units, the elite Special Boat Squadron (SBS) and the Rapid Action Boat Squadron (RABS).
The Welfreighter was a Second World War British midget submarine developed by the Special Operations Executive (SOE) for the purpose of landing and supplying agents behind enemy lines. It only saw action once and was not particularly successful.
An assault boat is a boat used for landing in combat, specifically for inland waters. Their lightweight construction allows for them to be carried by multiple men on foot. They can either be paddled or fitted with an outboard motor for high-speed operation. Some assault boats can be fitted with small firearms such as automatic rifles. Larger assault boats are used in riverine and littoral water where the boat can easily berth in tight spaces and shallow waters. The length of assault boats is usually 5 to 20 meters and they are constructed from rubber, fiberglass, aluminum, or steel.
The MTSM motor torpedo boat was a series of small motor torpedo boats developed by the Regia Marina during World War II.
The O'Day 23 is a series of American trailerable sailboats, that were designed by C. Raymond Hunt Assoc. and first built in 1972.
The Cornish Crabber 24 is a series of British trailerable sailboats, designed by Roger Dongray as cruisers and first built in 1974.
