34-431: Underway , or under way , is a nautical term describing the state of a vessel which is unconstrained from horizontal translational movement relative to the water and the ground. "Way" arises when there is sufficient water flow past the rudder of a vessel that it can be steered. A vessel is said to be underway if it meets the following criteria: If a vessel is adrift and not being propelled by any instrument or device , it
68-978: A boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats , and sailboats . House boats may be used for vacationing or long-term residence. Lighters are used to move cargo to and from large ships unable to get close to shore. Lifeboats have rescue and safety functions. Boats can be propelled by manpower (e.g. rowboats and paddle boats ), wind (e.g. sailboats ), and inboard / outboard motors (including gasoline , diesel , and electric ). The earliest watercraft are considered to have been rafts . These would have been used for voyages such as
102-489: A boat's hull and covered over with cement. Reinforced with bulkheads and other internal structures it is strong but heavy, easily repaired, and, if sealed properly, will not leak or corrode. As the forests of Britain and Europe continued to be over-harvested to supply the keels of larger wooden boats, and the Bessemer process ( patented in 1855) cheapened the cost of steel, steel ships and boats began to be more common. By
136-409: A framework with animal skins, could be equally as old as logboats, but such a structure is much less likely to survive in an archaeological context. Plank-built boats are considered, in most cases, to have developed from the logboat. There are examples of logboats that have been expanded: by deforming the hull under the influence of heat, by raising up the sides with added planks, or by splitting down
170-661: A half-size reconstruction of a Ferriby boat in Southampton. They have experimented with using a sail; although there is no evidence of a sail in the originals, they successfully rigged a square sail to Oakleaf. Oakleaf was then acquired by the Ferriby Heritage Trust in 2008, and it is now kept at Ferriby. In 2012–13, the Morgawr , a full-scale fully functional reconstruction (replica) of the Ferriby 1 boat,
204-433: A modern context, empty oil drums). The key difference between a raft and a boat is that the former is a "flow through" structure, with waves able to pass up through it. Consequently, except for short river crossings, a raft is not a practical means of transport in colder regions of the world as the users would be at risk of hypothermia . Today that climatic limitation restricts rafts to between 40° north and 40° south, with, in
238-681: A similar period have been found in Britain and the Ferriby examples are the earliest known sewn-plank boats found in Europe, as well as the oldest known sewn-plank boats in the world outside of Egypt . Ferriby is on the edge of a major estuary into the North Sea, the Humber , so speculation has been made ever since their discovery about whether they went to sea and sailed to the Continent. There
272-402: Is a watercraft of a large range of types and sizes, but generally smaller than a ship , which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes , or in protected coastal areas. However, some boats (such as whaleboats ) were intended for offshore use. In modern naval terms,
306-410: Is a modern construction method, using wood as the structural component. In one cold molding process, very thin strips of wood are layered over a form. Each layer is coated with resin, followed by another directionally alternating layer laid on top. Subsequent layers may be stapled or otherwise mechanically fastened to the previous, or weighted or vacuum bagged to provide compression and stabilization until
340-542: Is also known as "GRP" (glass-reinforced plastic) in the UK, and "FRP" (for fiber-reinforced plastic) in the US. Fiberglass boats are strong and do not rust, corrode, or rot. Instead, they are susceptible to structural degradation from sunlight and extremes in temperature over their lifespan. Fiberglass structures can be made stiffer with sandwich panels, where the fiberglass encloses a lightweight core such as balsa or foam. Cold molding
374-680: Is plenty of evidence that there was cross-channel communication, but it is not known what kind of boats actually sailed across. Keith Miller, a regional archaeologist told the BBC that Ferriby boats would have been used to cross the North Sea, though by modern standards, such vessels as these are considered suitable only for sheltered waters. Nonetheless, the Ferriby Heritage Trust describe Ferriby Boat 3 as Europe's oldest known seacraft. The BBC television programme Operation Stonehenge: What Lies Beneath Pt 2, broadcast on BBC Two in September 2014, describes
SECTION 10
#1732793988176408-587: Is said to be underway, not making way. "Under weigh" is a variation, coming from folk etymology, first used in 1749. "Under way" is likely from the Dutch onderweg or Middle Dutch onderwegen (lit. "under" or "among the ways"). Weigh is also a synonym for hanging or dangling, so that the process of raising an anchor, which causes it to hang at the end of the anchor-rope or chain is called “weighing [the] anchor” which leads to confusion between weigh and way, since both are pronounced identically. Boat A boat
442-490: Is the main, and in some cases only, structural component of a boat. It provides both capacity and buoyancy . The keel is a boat's "backbone", a lengthwise structural member to which the perpendicular frames are fixed. On some boats, a deck covers the hull, in part or whole. While a ship often has several decks, a boat is unlikely to have more than one. Above the deck are often lifelines connected to stanchions , bulwarks perhaps topped by gunnels , or some combination of
476-576: The Baltic , the Plimsoll line was introduced to prevent overloading. Since 1998 all new leisure boats and barges built in Europe between 2.5m and 24m must comply with the EU 's Recreational Craft Directive (RCD). The Directive establishes four categories that permit the allowable wind and wave conditions for vessels in each class: Europe is the main producer of recreational boats (the second production in
510-462: The birch bark canoe , the animal hide-covered kayak and coracle and the dugout canoe made from a single log. By the mid-19th century, some boats had been built with iron or steel frames but still planked in wood. In 1855 ferro-cement boat construction was patented by the French, who coined the name "ferciment". This is a system by which a steel or iron wire framework is built in the shape of
544-401: The 1920s, but it was not until the mid-20th century that aluminium gained widespread popularity. Though much more expensive than steel, aluminum alloys exist that do not corrode in salt water, allowing a similar load carrying capacity to steel at much less weight. Around the mid-1960s, boats made of fiberglass (aka "glass fiber") became popular, especially for recreational boats. Fiberglass
578-400: The 1930s boats built entirely of steel from frames to plating were seen replacing wooden boats in many industrial uses and fishing fleets. Private recreational boats of steel remain uncommon. In 1895 WH Mullins produced steel boats of galvanized iron and by 1930 became the world's largest producer of pleasure boats. Mullins also offered boats in aluminum from 1895 through 1899 and once again in

Details concerning the boats can be found on an information board on Ferriby foreshore, on a public footpath that forms part of the Trans Pennine Trail . Two different replicas have been made of the Ferriby Boats. In 2002-2003, Edwin Gifford and his team that included Richard Darrah built and sailed
646-435: The Ferriby boats (pictured) was given a pointed bow and the Ferriby boats are described by the museum that houses them as having curved rocker bottoms, which qualifies them as similar to the later Dover boat in their seagoing abilities. In 1937, the first boat, known as Ferriby Boat 1 (or F1), was discovered by Ted and Will Wright, on the shore of the Humber. It was a boat bottom with one end almost complete. What remained
680-441: The balance above and below the surface equal. Boats have a natural or designed level of buoyancy. Exceeding it will cause the boat first to ride lower in the water, second to take on water more readily than when properly loaded, and ultimately, if overloaded by any combination of structure, cargo, and water, sink. As commercial vessels must be correctly loaded to be safe, and as the sea becomes less buoyant in brackish areas such as
714-598: The boat as seagoing and describes the tons of cargo it could have taken across the Channel. However, the Dover Museum consider that the Dover Bronze Age Boat is the oldest seagoing boat known, at only 1550 BC, as the lack of a rocker bottom and pointed prow on the Ferriby boats is deemed by some to have made them too unstable for sea crossings. This is contested though: The Oakleaf reproduction of

In 2014, having been in the water for many months, she was lifted out for her condition to be inspected and studied. As of 2016, she is on land, on display next to the Maritime Museum. In 1985 samples of the tree-rings of all three boats were examined. Measuring
782-441: The end of a second boat-plank in 1940. This has become known as Ferriby Boat 2 (or F2). It is a twin-planked centre-strake dated to between 1940 and 1720 BC. In 1963, part of a third boat was discovered, again by Ted Wright, this time in the company of one of his sons, Roderick, and excavated adjoining Ferriby Boat 1. The remains consist of part of an outer bottom-strake and associated side-strake; many years later (in
816-502: The late 1990s), scientists from Oxford were able to demonstrate that the third boat dated from as far back as 2030 BC, by the analysis of samples of the boat using accelerator mass spectrometry. Ted Wright had formulated this theory much earlier, as set out in his book "The Ferriby Boats: Seacraft of the Bronze Age", published in 1990. The original boats were excavated in 1946 and had to be cut up to be moved. They were housed in
850-453: The middle and adding a central plank to make it wider. (Some of these methods have been in quite recent use – there is no simple developmental sequence). The earliest known plank-built boats are from the Nile, dating to the third millennium BC. Outside Egypt, the next earliest are from England. The Ferriby boats are dated to the early part of the second millennium BC and the end of
884-752: The past, similar boundaries that have moved as the world's climate has varied. The earliest boats may have been either dugouts or hide boats. The oldest recovered boat in the world, the Pesse canoe , found in the Netherlands , is a dugout made from the hollowed tree trunk of a Pinus sylvestris that was constructed somewhere between 8200 and 7600 BC. This canoe is exhibited in the Drents Museum in Assen, Netherlands. Other very old dugout boats have also been recovered. Hide boats, made from covering
918-406: The resin sets. An alternative process uses thin sheets of plywood shaped over a disposable male mold, and coated with epoxy. The most common means of boat propulsion are as follows: A boat displaces its weight in water, regardless whether it is made of wood, steel, fiberglass, or even concrete. If weight is added to the boat, the volume of the hull drawn below the waterline will increase to keep
952-400: The ring-thicknesses needed to try and match other ring patterns proved difficult, partly because the boats were already treated. No actual dates were possible, but some information was obtained and the record of ring-thicknesses has been retained for future comparisons. The studies revealed that a pair of bottom strakes were split from the same trunk and that boats 1 and 2 may have been felled at
986-492: The settlement of Australia sometime between 50,000 and 60,000 years ago. A boat differs from a raft by obtaining its buoyancy by having most of its structure exclude water with a waterproof layer, e.g. the planks of a wooden hull, the hide covering (or tarred canvas) of a currach . In contrast, a raft is buoyant because it joins components that are themselves buoyant, for example, logs, bamboo poles, bundles of reeds, floats (such as inflated hides, sealed pottery containers or, in
1020-721: The third millennium. Plank-built boats require a level of woodworking technology that was first available in the neolithic with more complex versions only becoming achievable in the Bronze Age . Boats can be categorized by their means of propulsion. These divide into: A number of large vessels are usually referred to as boats. Submarines are a prime example. Other types of large vessels which are traditionally called boats include Great Lakes freighters , riverboats , and ferryboats . Though large enough to carry their own boats and heavy cargo, these vessels are designed for operation on inland or protected coastal waters. The hull
1054-518: The two. A cabin may protrude above the deck forward, aft, along the centerline, or cover much of the length of the boat. Vertical structures dividing the internal spaces are known as bulkheads . The forward end of a boat is called the bow , the aft end the stern . Facing forward the right side is referred to as starboard and the left side as port . Until the mid-19th century, most boats were made of natural materials, primarily wood, although bark and animal skins were also used. Early boats include
