72-577: Dunbar Lifeboat Station is a lifeboat station located in Dunbar Harbour at Dunbar , on the south-east coast of Scotland , operated by the Royal National Lifeboat Institution . The station operates a Trent-class all-weather lifeboat and a D-class (IB1) inshore lifeboat. Dunbar is one of the earlier British ports to be served by a lifeboat, the first station being constructed in 1808. Dunbar Harbour has been

The design won a competition organised by the private Law House committee, though William Wouldhave and Lionel Lukin both claimed to be the inventor of the first lifeboat. Greathead's boat, the Original (combined with some features of Wouldhave's) entered service in 1790 and another 31 of
216-978: 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
288-489: 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

The initiative to establish a station at Dunbar came from George Miller , a native of the town, son of a merchant and established as a bookbinder and bookseller, but having had a long fascination with seafaring. By his own account, he had as a child conceived of mortar-launched lines as a means of reaching shoreline wrecks, many years in advance of George William Manby's successful implementation of

In Britain, the history of lifeboats dates (two outliers excepted) to Henry Greathead's 1790 boat at South Shields on the River Tyne in England; in 1824 the Royal National Lifeboat Institution
504-409: 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
576-428: A high capacity in the number of person that could be rescued of approximately 100 and could tow ten fully loaded standard life boats used by most merchant vessels. Unlike the older 36-foot, the 52-foot MLBs had a diesel engine. The 52-foot wooden-hulled MLBs were the only Coast Guard vessels less than 65 feet (20 m) in length that were given names, CG-52300 Invincible and CG-52301 Triumph . Both were built at

In the mid-1930s the USCG ordered two 52-foot wooden-hulled motor lifeboats (MLBs) for service where there was a high traffic of merchants ships and heavy seas that had
720-433: 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
792-578: A national organisation in 1824 with the establishment of the Royal National Lifeboat Institution . One example of an early lifeboat was the Landguard Fort Lifeboat of 1821, designed by Richard Hall Gower . In 1851, James Beeching and James Peake produced the design for the Beeching–Peake SR (self-righting) lifeboat which became the standard model for the new Royal National Lifeboat Institution fleet. The first motorised boat,

#1732775951418864-663: A range of 150–250 nautical miles. Characteristics such as capability to withstand heavy weather, fuel capacity, navigation and communication devices carried, vary with size. A vessel and her crew can be used for operation out to 20 nautical miles (37 km) away from a place of safe refuge, remaining at or on the scene to search for several hours, with fuel reserves sufficient for returning; operating in up to gale force sea conditions; in daylight, fog and darkness. A smaller inshore rescue boat (IRB) or inshore life boat (ILB) and her crew would not be able to withstand (or even survive) these conditions for long. In countries such as Canada and
936-541: A two-ton lead keel, she was powered by a 90 hp (67 kW) Sterling gas engine and had a speed of nine knots (17 km/h). From the early days of the 20th century the 36 MLB was the mainstay of coastal rescue operations for over 30 years until the 44 MLB was introduced in 1962. Built at the Coast Guard Yard in Curtis Bay, Maryland, 218 36 T, TR and TRS MLBs were built between 1929 and 1956. Based on

This means that the boats are designed to operate with water inside the boat hull and rely on flotation tanks rather than hull displacement to stay afloat and upright. Inflatables (IB)s fell out of general use after the introduction of RIBs during the 1970s. Conditions in New Zealand and other large surf zones was identified and Inflatable Rescue Boats (IRB), small non rigid powered boats, were introduced by New Zealand at Piha Beach and have been put into use in many other countries including Australia and
1080-455: Is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, inflatable or rigid-inflatable combination-hulled vessels. There are generally three types of boat, in-land (used on lakes and rivers), in-shore (used closer to shore) and off-shore (into deeper waters and further out to sea). A rescue lifeboat
1152-402: 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,
1224-481: Is a boat designed with specialised features for searching for, rescuing and saving the lives of people in peril at sea or other large bodies of water. In the United Kingdom and Ireland rescue lifeboats are typically vessels crewed by volunteers, intended for quick dispatch, launch and transit to reach a ship or individuals in trouble at sea. Off-shore boats are referred to as 'All-weather' and generally have
1296-410: 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
1368-542: 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
1440-645: Is being developed for deployment sometime in 2013. The FCB2 class of lifeboat was on 11 April 2011 accepted as a proven design and given the class name Shannon , continuing the RNLI tradition of naming all-weather lifeboat classes after rivers in the British Isles. Scarborough lifeboat station in North Yorkshire and Hoylake lifeboat station on the Wirral are two of the first stations to be allocated one of

Designed to be self-bailing , self-righting and practically unsinkable, MLBs are used for surf rescue in heavy weather. The 36-foot (11 m) T model was introduced in 1929. At 36 ft 10 in (11.23 m) length overall, 10 ft 9 in (3.28 m) beam and with

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
1656-498: Is twin Detroit Diesel 6v53s that put out 185 hp (138 kW) each at a max RPM of 2800. Another surf capable boat that the Coast Guard has used in recent years is the 30' surf rescue boat (SRB) introduced in 1983. The 30' SRB was self-righting and self bailing and designed with marked differences from the typical lifeboats used by the Coast Guard up until the early 1980s. The 30' SRB is not considered to be an MLB, but
1728-656: The 47 footer (respectively). The SNSM operates over 500 boats crewed by more than 3200 volunteers, from all-weather lifeboats to jetskis, dispersed in 218 stations (including 15 in overseas territories). In 2009 the SNSM was responsible for about half of all sea rescue operations and saved 5,400 lives in 2816 call-outs and assisted 2140 boats in distress. The service has 41 all-weather rescue boats, 34 first-class rescue boats, 76 second-class lifeboats and 20 light rescue boats (and an amphibious rescue boat), and many inflatable boats. All these boats are made unsinkable by injection into
1800-629: 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

In 1929 the motorised lifeboat Princess Mary was commissioned and was the largest oceangoing lifeboat at that time, able to carry over 300 persons on rescue missions. The Princess Mary was stationed at Padstow in Cornwall, England. The United States Life Saving Service (USLSS) was established in 1848. This was a United States government agency that grew out of private and local humanitarian efforts to save
1944-661: The New Zealand Lifeguard Service to reintroduce small 2 man IRB's, which have since been adopted by other organisations such as the RNLI as well. Larger non-inflatable boats are also employed as lifeboats. The RNLI fields the Severn class lifeboat and Tamar class lifeboat as all-weather lifeboats (ALB). In the United States and Canada, the term motor life boat ( MLB ) refers to a similar (though slightly smaller) class of non-inflatable lifeboats,
2016-866: The RNLI , Canadian Coast Guard and others under licence from the USCG. The last active 44' MLB in the United States Coast Guard was retired in May 2009, however these boats are still in active service elsewhere around the globe. The 44' MLB can be found in many third world countries and is faithfully serving the Royal Volunteer Coastal Patrol in Australia and the Royal New Zealand Coastguard Federation. The current engine configuration

In time Invincible was also transferred to the Pacific Northwest at Station Grays Harbor. Triumph later capsized and sank during a rescue mission on January 12, 1961. By that time, the Coast Guard had already built two of the four steel-hulled successor 52-foot Motor Lifeboats . As of 2019 ,

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
2376-401: 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
2448-400: 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

The sand bars which form at the entrance are treacherous and provide a tough training environment for surf lifesavers. Canada established its first lifeboat stations in the mid-to-late 19th century along the Atlantic and Pacific coasts, as well as along the shores of the Canadian side of the Great Lakes. The original organisation

The Dutch lifeboat association Koninklijke Nederlandse Redding Maatschappij (KNRM) has developed jet-driven RIB lifeboats. This has resulted in 3 classes, the largest is the Arie Visser class: length 18,80 m, twin jet, 2 x 1,000 hp (750 kW), max. speed 35 knots (65 km/h), capacity 120 persons. Some local lifeguard organisations also respond on

In Auckland, New Zealand two 15-foot surf jet rescue boat powered by three stage Hamilton jet units were stationed in the 1970s and 1980s at Piha Beach the home of the Piha Surf Life Saving Club . The Canadian Coast Guard operates makes and models of motor lifeboats that are modified RNLI and USCG designs such as the Arun and
2808-708: The RNLI in the UK. In Australasia surf lifesaving clubs operate inflatable rescue boats (IRB) for in-shore rescues of swimmers and surfers. These boats are best typified by the rubber Zodiac and are powered by a 25-horsepower outboard motor. In the off season, these boats are used in competitive rescue racing. In addition to this, most states have a power craft rescue service. RWCs (Rescue Water Craft, Jetski) are common to many beaches, providing lifesaving service. The state of New South Wales operates dual hull fiberglass offshore boats, while Queensland, Tasmania and South Australia operate aluminum hull Jet Rescue Boats, of about 6m in length. Some regions such as North Queensland and
2880-487: The SAR. Most Scandinavian countries also have volunteer lifeboat societies. The Royal National Lifeboat Institution (or RNLI) maintains lifeboats around the coasts of Great Britain and Ireland crewed largely by unpaid volunteers, most part-time, with equipment funded through voluntary donations. In Britain, the RNLI design and build several types of all-weather motor lifeboats, the Arun class kept permanently afloat,

Its task is saving lives at sea around the French coast, including the overseas départments and territories. Lifeboats have been modified by the addition of an engine since 1890 which provides more power to get in and out of the swell area inside the surf. They can be launched from shore in any weather and perform rescues further out. Older lifeboats relied on sails and oars which are slower and dependent on wind conditions or manpower. Modern lifeboats generally have electronic devices such as radios and radar to help locate

3024-440: The United States, the term 'motor lifeboat', or its US military acronym MLB, is used to designate shore-based rescue lifeboats which are generally crewed by full-time coast guard service personnel. These vessels stay on standby service rather than patrolling in the water, like a crew of fire fighters standing by for an alarm. In Canada, some lifeboats are 'co-crewed', meaning that the operator and engineer are full-time personnel while
3096-516: The affairs of the lifeboat station brought the Dunbar service to an end sometime after 1818, when damage occasioned to the Greathead boat went unrepaired, and it was found to be unavailable to assist with an 1821 wrecking. From about 1830, Dunbar was served by a Rocket Brigade using Mandy apparatus. It was not until 1864 that the town petitioned to the reinvigorated RNLI for a replacement boat; by 1865
3168-441: 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
3240-565: The canyon sides. The first lifeboat station in Britain was at Formby beach, established in 1776 by William Hutchinson , Dock Master for the Liverpool Common Council. The first non-submersible ('unimmergible') lifeboat is credited to Lionel Lukin , an Englishman who, in 1784, modified and patented a 20-foot (6.1 m) Norwegian yawl , fitting it with water-tight cork-filled chambers for additional buoyancy and
3312-685: The canyon-like gorge conditions along the river shore and the high volume and rate of flow. The 'long river' was a principal means of communication between coastal (Shanghai) and interior China ( Chongqing , once known as Chungking). These river lifeboats, usually painted red, were of a wooden pulling boat design, with a very narrow length-to-beam ratio and a shallow draft for negotiating shoal waters and turbulent rock-strewn currents. They could thus be maneuvered sideways to negotiate rocks, similar to today's inflated rafts for 'running' fast rivers, and also could be hauled upstream by human haulers, rather than beasts of burden, who walked along narrow catwalks lining
3384-420: The crew members are trained volunteers. Older inflatable boats, such as those introduced by the Royal National Lifeboat Institution (RNLI) and Atlantic College in 1963, were soon made larger and those over 3 metres (9.8 ft) often had plywood bottoms and were known as RIBs. These two types were superseded by newer types of RIBs which had purpose built hulls and flotation tubes. A gap in operations caused

He floated a proposal for a lifeboat in the Edinburgh Evening Courant and quickly a committee of local worthies was formed, and as quickly, a subscription raised above £366, which by 1808 yielded lifeboat, station, carriage and minimal float for expenses. David Anderson's 2002 paper on The Dunbar Lifeboat notes five occasions on which it responded to mariners in distress, but notes that there are no good records of its employment. Lack of competent management of

All-weather lifeboats from 15 meters to 18 meters are self-righting. The first class lifeboat have capacities close to the all-weather rescue boats, the second class lifeboat are intended for slightly less difficult conditions. The first and second class boats, respectively 14 meters and 12 meters, which are

A regular lifeboat service operated from 1854 to 1940 along the middle reaches of the Chang jiang or Yangtze , a major river which flows through south central China. These waters are particularly treacherous to waterway travellers owing to

In 1899 the Lake Shore Engine Company, at the behest of the Marquette Life Saving Station, fitted a two-cylinder 12 hp (8.9 kW) engine to a 34-foot (10 m) lifeboat on Lake Superior , Michigan . Its operation marked the introduction of

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
3888-479: The most recent boats, are self-righting. The boats are dispersed in 185 stations (including 15 in overseas territories). In Germany , the German Maritime Search and Rescue Service (DGzRS) has provided naval rescue service since 1865. It is a civilian, non-profit organisation which relies entirely on individual funding (no government support) and has a variety of boats and ships, the biggest being
3960-658: The new boats. Scarborough's Shannon class lifeboat will be named Frederick William Plaxton in his memory as he left a substantial legacy to the RNLI specifically to purchase Scarborough's next all-weather lifeboat. There are at least 70 lifeboat services in Britain and Ireland that are independent of the RNLI, providing lifeboats and crews 24 hours a day all year round, manned by unpaid volunteers. They operate inland, inshore or offshore, according to local needs. The United States Life Saving Service began using motorised lifeboats in 1899. Models derived from this hull design remained in use until 1987. Today in U.S. waters rescue-at-sea

The Rigid Hulled Inflatable Boat (RHIB) is now seen as the best type of craft for in-shore rescues as they are less likely to be tipped over by the wind or breakers. Specially designed jet rescue boats have also been used successfully. Unlike ordinary pleasure craft these small to medium-sized rescue craft often have

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
4248-467: The phasing out of the 44' MLBs made the 30 footers obsolete. The class of vessels underwent an overhaul in the early nineties to extend their life until the newer and faster 47' motor lifeboats came into service, and in the late 1990s most of the 30 footers were de-commissioned. One still remains on active duty at Motor Lifeboat Station Depoe Bay in Depoe Bay, Oregon and is used almost daily. This station
4320-406: 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

In 1807 Ludkin designed the Frances Ann for the Lowestoft service, which wasn't satisfied with Greathead's design, and this saved 300 lives over 42 years of service. The first self-righting design was developed by William Wouldhave and also entered in the Law House competition, but

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

These steel-hulled boats were more capable and more complicated than the wooden lifeboats they replaced. In all 110 vessels would be built by the Coast Guard Yard in Curtis Bay between 1962 and 1972 with an additional 52 built by

The sailors of the MLBs are called "surfmen" , after the name given to the volunteers of the original USLSS. The main school for training USCG surfmen is the National Motor Lifeboat School (NMLBS) located at the Coast Guard Station Cape Disappointment at the mouth of

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

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
4824-570: Was called the "Canadian Lifesaving Service", not to be confused with the Royal Life Saving Society of Canada , which came later at the turn of the 20th century. In 1908, Canada had the first lifeboat (a pulling sailing boat design) to be equipped with a motor in North America, at Bamfield , British Columbia. The Société Nationale de Sauvetage en Mer (SNSM) is a French voluntary organisation founded in 1967 by merging
4896-458: Was driven ashore. The Sir Ronald Pechell Bt , valued at £208K in 2008, cost £1.05M to build in 1995 and in her 13 years of service at Dunbar had launched 206 times and rescued 171 people. The lifeboat, 14-35 John Neville Taylor (ON 1266) from the charity's relief fleet, has been allocated to the station as a permanent replacement. The following are awards made to the crew of Dunbar Lifeboat Station: Lifeboat (rescue) A rescue lifeboat
4968-403: Was founded to take a nationwide interest in the provision of lifeboats, but it was relatively ineffective in its earliest years. Lifeboat provision prior to about 1850 was a matter for local communities, with little institutional support. Dunbar ranks amongst the earlier harbours to be equipped with a lifeboat, equipping itself with a boat of Henry Greathead's design and manufacture, together with
5040-420: Was generally used in a similar capacity. Designed to perform search and rescue in adverse weather the vessel is generally operated with a crew of two, a surfman and an engineer. The crew both stand on the coxswain flat, protected by the superstructure on the bow and stern. The boat's appearance has caused many to comment that it looks like a "Nike Tennis Shoe". Since 1997 the introduction of the faster 47' MLB and
5112-552: Was host to the last 36' motor lifeboat in the late 1980s. The USCG has since designed and built new aluminum 47-foot (14 m) lifeboats and the first production boat was delivered to the USCG in 1997. The 47-Foot Motor Lifeboat is able to withstand impacts of three times the acceleration of gravity, can survive a complete roll-over and is self-righting in less than 10 seconds with all machinery and instruments remaining fully operational. The 47' MLB can travel at 25 knots (46 km/h) to reach her destination. Boat A boat
5184-612: Was only awarded a half-prize. Self-righting designs were not deployed until the 1840s. These lifeboats were crewed by 6 to 10 volunteers who would row out from shore when a ship was in distress. In the case of the UK the crews were generally local boatmen. One example of this was the Newhaven Lifeboat, established in 1803 in response to the wrecking of HMS Brazen in January 1800, when only one of her crew of 105 could be saved. The UK combined many of these local efforts into
