A barge is a shoal-draft flat-bottomed boat, built mainly for river and canal transport of bulk goods. Originally barges were towed by draft horses on an adjacent towpath. Barges have changed throughout time. From 1967 to 1983 barges were considered a flat bottom boat that was nineteen feet in length or larger. Today, barges may be self-propelled, usually with a slow-revving diesel engine and a large-diameter fixed-pitch propeller. Otherwise, "dumb barges" must be towed by tugs, or pushed by pusher boats. Compared to a towed barge, a pusher system has improved handling and is more efficient, as the pushing tug becomes "part of the unit" and it contributes to the momentum of the whole.
A scow is a type of flat-bottomed barge. Some scows are rigged as sailing scows. In the 19th and early 20th centuries, scows carried cargo in coastal waters and inland waterways, having an advantage for navigating shallow water or small harbours. Scows were in common use in the American Great Lakes and other parts of the U.S., in southern England, and in New Zealand. In Canada, scows have traditionally been used to transport cattle to the islands of New Brunswick's Saint John River. In modern times their main purpose is for recreation and racing.
A Mersey flat is a type of doubled-ended barge with rounded bilges, carvel build and fully decked. Traditionally, the hull was built of oak and the deck was pitch pine. Some had a single mast, with a fore-and-aft rig, while some had an additional mizzen mast. Despite having a flat bottom and curved sides, they were quite stable. They were common from the 1730s to 1890s.
A Thames sailing barge is a type of commercial sailing boat once common on the River Thames in London. The flat-bottomed barges with a shallow draught and leeboards, were perfectly adapted to the Thames Estuary, with its shallow waters and narrow tributary rivers. The larger barges were seaworthy vessels, and were the largest sailing vessel to be handled by just two men. The average size was about 120 tons and they carried 4,200 square feet (390 m2) of canvas sail in six working sails. The mainsail was loose-footed and set up with a sprit, and was brailed to the mast when not needed. It is sheeted to a horse, as is the foresail; they require no attention when tacking. The foresail is often held back by the mate to help the vessel come about more swiftly.
A leeboard is a form of pivoting keel used by a sailboat in lieu of a fixed keel. Typically mounted in pairs on each side of a hull, leeboards function much like a centreboard, allowing shallow draft craft to ply waters fixed keel boats cannot. Only one, however, the leeward, is used at a time, as it does not get lifted from the water when the boat heels under the force of the wind.
The term skiff is used for a number of essentially unrelated styles of small boats. Traditionally, these are coastal craft or river craft used for leisure, as a utility craft and for fishing, and have a one-person or small crew. Sailing skiffs have developed into high performance competitive classes. Many of today's skiff classes are based in Australia and New Zealand in the form of 12 ft (3.66 m), 13 ft (3.96 m), 16 ft (4.88 m) and 18 ft (5.49 m) skiffs. The 29er, 49er, SKUD and Musto Skiff are all considered to have developed from the skiff concept, all of which are sailed internationally.
Philip C. Bolger was a prolific American boat designer, who was born and lived in Gloucester, Massachusetts. He began work full-time as a draftsman for boat designers Lindsay Lord and then John Hacker in the early 1950s.
A pram or pramm describes a type of shallow-draught flat-bottomed ship, usually propelled by pushing the ship through the water using a long pole, although sailing prams also exist. The name pram derives from the Latin premere.
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning.
A chine in boat design is a sharp change in angle in the cross section of a hull. The chine typically arises from the use of sheet materials as the mode of construction.
A hoy was 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.
A galiot, galliot or galiote, was a small galley boat propelled by sail or oars. There are three different types of naval galiots that sailed on different seas.
A Dutch barge is a traditional flat-bottomed shoal-draught barge, originally used to carry cargo in the shallow Zuyder Zee and the waterways of Netherlands. There are very many types of Dutch barge, with characteristics determined by regional conditions and traditions.
A gundalow is a type of flat-bottomed sailing barge once common in Maine and New Hampshire rivers. They first appeared in the mid-1600s, reached maturity of design in the 1700 and 1800s, and lingered into the early 1900s before vanishing as commercial watercraft. Up to 70 feet (21.34 m) long, they characteristically employed tidal currents for propulsion, with a single huge lateen sail brailed to a heavy yard to harness favorable winds.
Thalatta is a Thames sailing barge, built in Harwich, Essex, in 1906 and rebuilt in St Osyth in 2012. She is 90 feet (27 m) long and 26 feet (7.9 m) across the widest part of the deck. Like all Thames barges, she is flat-bottomed and has leeboards instead of a keel. She spent some of her life ketch-rigged and some of it spritsail-rigged. She is now permanently spritsail rigged, and has a mainmast and topmast that, together, are about 90 feet (27 m) high, and a mizzen mast. Thalatta has had two periods with an auxiliary engine and two without. She carried cargo for sixty years and was then converted for use as a sail training ship in 1966. She was completely rebuilt between 2006 and 2012 at St Osyth with assistance from lottery funds.
A koff is a historical type of sailing vessel that was used for coastal shipping off Belgium, the Netherlands, and Germany in the 18th and 19th centuries. A typical koff had one and a half masts with a gaff rigged main sail and spanker and one or two square sails in the main top. The hull was plump with a flat bottom and a heavily rounded, raised bow and stern. Smaller koffs could be equipped with leeboards. Due to the shallow draught, koffs were especially suited for inshore shipping in shallow waters.
SB Centaur is a wooden Thames sailing barge, built in Harwich, Essex, England in 1895. She was used to carry various cargoes, mainly grain, for the next 60 years. During the First World War she carried food and coal to the French Channel ports. During the Second World War Centaur was damaged when sailing to assist with the Dunkirk Evacuation. She did war work for the duration of the conflict.
The Ena is a wooden Thames sailing barge constructed in Harwich in 1906 that is resting on the flats adjacent to Stargate Marina in Hoo, Kent. She is a notable Dunkirk little ship reputed to have rescued 100 men.
