Longships were sea vessels made and used by the Vikings from the Nordic countries for trade, commerce, exploration, and warfare during the Viking Age although scientific analysis of the oak timber shows at least one well known ship was built in Dublin, Ireland. The longship’s design evolved over many years, beginning in the Stone Age with the invention of the umiak and continuing up to the 9th century with the Nydam and Kvalsund ships. The longship appeared in its complete form between the 9th and 13th centuries. The character and appearance of these ships have been reflected in Scandinavian boat-building traditions until today. The particular skills and methods employed in making longships are still used world wide, often with modern adaptations. They were all made out of wood, with cloth flags and had lots of details and carvings on the hull.
The longship is characterized as a graceful, long, narrow, light, wooden boat with a shallow-draft hull designed for speed. The ship's shallow draft allowed navigation in waters only one metre deep and permitted beach landings, while its light weight enabled it to be carried over portages. Longships were also double-ended, the symmetrical bow and stern allowing the ship to reverse direction quickly without having to turn around; this trait proved particularly useful in northern latitudes where icebergs and sea ice posed hazards to navigation. Longships were fitted with oars along almost the entire length of the boat itself. Later versions had a rectangular sail on a single mast which was used to replace or augment the effort of the rowers, particularly during long journeys. The average speed of Viking ships varied from ship to ship but lay in the range of 5–10 knots and the maximum speed of a longship under favorable conditions was around 15 knots.
Longships were the epitome of Scandinavian naval power at the time, and were highly valued possessions. They were often owned by coastal farmers and commissioned by the king in times of conflict, in order to build a powerful naval force. While longships were used by the Norse in warfare, they were troop transports, not warships. In the tenth century, these boats would sometimes be tied together in battle to form a steady platform for infantry warfare. During the 9th century peak of the Viking expansion, large fleets set out to attack the degrading Frankish empire by attacking up navigable rivers such as the Seine. Rouen was sacked in 841, the year after the death of Louis the Pious, a son of Charlemagne. Quentovic, near modern Etables, was attacked in 842 and 600 Danish ships attacked Hamburg in 845. In the same year 129 ships returned to attack up the Seine. They were called "dragonships" by enemies such as the English because they had a dragon-shaped bow. The Norse had a strong sense of naval architecture, and during the early medieval period they were advanced for their time.

Types of longships[edit | edit source]
Longships can be classified into a number of different types, depending on size, construction details, and prestige. The most common way to classify longships is by the number of rowing positions on board.
Karvi[edit | edit source]
The Karvi are the smallest vessel that is considered a longship. According to the 10th century Gulating Law, a ship with 13 rowing benches is the smallest ship suitable for military use. A ship with between 6 and 16 benches would be classified as a Karvi. These ships were considered to be “general purpose” ships, mainly used for fishing and trade, but occasionally were commissioned for military use. While most longships held a length to width ratio of 7:1, the Karvi ships were closer to 4.5:1. The Gokstad Ship is a famous Karvi ship, built around the end of the 9th century, excavated in 1880 by Nicolay Nicolyasen. It was approximately 23 metres (75 ft) long with 16 rowing positions.
Snekkja[edit | edit source]
The snekkja, meaning 'thin and projecting,' was typically the smallest longship used in warfare and was classified as a ship with at least 20 rowing benches. A typical snekkja might have a length of 17 metres (56 ft), a width of 2.5 metres (8.2 ft), and a draught of only 0.5 metres (1.6 ft). It would carry a crew of around 41 men (40 oarsmen and one cox).
Snekkjas were one of the most common types of ship. According to Viking lore, Canute the Great used 1,200 in Norway in 1028, and William the Conqueror used about 600 for the invasion of Britain in 1066 in the post Viking period.
The Norwegian snekkjas, designed for deep fjords and Atlantic weather, typically had more draught than the Danish model designed for low coasts and beaches. Snekkjas were so light that they had no need of ports – they could simply be beached, and potentially even carried across a portage.
The snekkjas continued to evolve after the end of the Viking age, with later Norwegian examples becoming larger and heavier than Viking age ships. They are still being used in Norway, and are now called snekke.
Skeid[edit | edit source]
Skeid (skeið), meaning ‘that which cuts through water,’ ships were larger warships, consisting of more than 30 rowing benches. Ships of this classification are some of the largest (see Busse) longships ever discovered. A group of these ships was discovered by Danish archaeologists in Roskilde during development in the harbor-area in 1962 and 1996-97. The ship discovered in 1962, Skuldelev 2 is an oak-built Skeid longship. It is believed to have been built in the Dublin area around 1042. Skuldelev 2 could carry a crew of some 70–80 and measures just less than 30 metres (98 ft) in length. In 1996-97 archaeologists discovered the remains of another ship in the harbour. This ship, called the Roskilde 6, has not yet been fully investigated and full details are not available. It is however thought to be around 36 metres (118 ft) long, and has been dated to the mid-11th century.
Drekkar[edit | edit source]
Drekkar are known from historical sources, such as the 13th century Göngu-Hrólfs Saga (the Saga of Rollo). Here, the ships are described as elegant and ornately decorated, and used by those who went raiding and plundering. According to the historical sources the ships' prows carried carvings of menacing beasts, such as dragons and snakes, allegedly to protect the ship and crew, and to ward off the terrible sea monsters of Norse mythology. It is however likely that the carvings, like those on the Oseberg ship, might have had a ritual purpose, or that the purported effect was to frighten enemies and townspeople. No true dragon ship, as defined by the sagas, has been found by archaeological excavation.
Transport[edit | edit source]
On 10 September 2007, Professor Stephen Harding of the University of Nottingham, used ground penetrating radar (GPR) equipment to pinpoint the location of a 1,000-year-old Viking transport longship (Nordic clinker design) beneath 6–10 feet (2–3 meters) of clay in Meols, Wirral, (a well-known settling place of Vikings). The ship had been previously uncovered in 1938 during excavation of a car park. Workers at the time covered the ship over again so as not to delay construction.
Construction[edit | edit source]
|date= }} The first longships can trace their origin back to between 500 and 300 BC, when the Danish Hjortspring boat was built. It was fastened with cord, not nailed, and paddled, not rowed. It had rounded cross sections and although 65 feet (20 m) long was only 6 feet (1.8 m) wide. The rounded sections gave maximum displacement for the lowest wetted surface area, similar to a modern narrow rowing skiff, so were very fast but had little carrying capacity. The shape suggests mainly river use. Unlike later boats, it had a low bow and stern. A distinctive feature is the two-prong cutaway bow section.
The first true longship, that was rowed was the Nydam ship built in Denmark around 350 AD. It also had very rounded underwater sections but had more pronounced flair in the topsides, giving it more stability as well as keeping more water out of the boat at speed or in waves. It had no sail. It was of lapstrake construction fastened with iron nails. The bow and stern had slight elevation. The keel was a flattened plank about twice as thick as a normal strake plank but still not strong enough to withstand the downwards thrust of a mast.
The Sutton Hoo longship, sometimes referred to as the ghost ship of the Wufflings, is about 27 metres (89 ft) x 4.5 metres (15 ft) maximum beam and built about 625 AD. It is associated with the Saxons. The ship was crushed by the weight of soil when buried but most details have been reconstructed. The ship was similar in hull section to the Nydam ship with flared topsides. Compared to later longships, the oak planks are wide-about 250 millimetres (9.8 in) including laps,with less taper at bow and stern. Planks were 25 millimetres (0.98 in) thick. The 26 heavy frames are spaced at 850 millimetres (33 in) in the centre. Each frame tapers from the turn of the bilge to the inwale. This suggests that knees were used to brace the upper two or three topside planks but appear to have rotted away. The hull had a distinctive leaf shape with the bow sections much narrower than the stern quarters. There were nine wide planks per side. The ship had a light keel plank but pronounced stem and stern deadwood. The reconstruction suggests the stern was much lower than the bow. It had a steering oar to starboard braced by an extra frame. The raised prow extended about 3.7 metres (12 ft) above the keel and the hull was estimated to draw 750 millimetres (30 in) when lightly laden. Between each futtock the planks were lapped in normal clinker style and fastened with six iron rivets per plank. There is no evidence of a mast, sail, or strengthening of the keel amidships but a half-sized replica, the Soe Wylfing, sailed very well with a modest sail area.
Sails started to be used from possibly the 8th century. The earliest had either plaited or chequered pattern, with narrow strips sewn together.
About 700 AD the Kvalslund ship was built. It is the first with a true keel. Its cross sectional shape was flatter on the bottom with less flair to the topsides. This shape is far more stable and able to handle rougher seas. It had the high prow of the later longships. After several centuries of evolution, the fully developed longship emerged some time in the middle of the ninth century. Its long, graceful, menacing head figure carved in the stern, such as the Oseburg ship, echoed the designs of its predecessors. The mast was now square in section and located toward the middle of the ship, and could be lowered and raised. The hull’s sides were fastened together to allow it to flex with the waves, combining lightness and ease of handling on land. The ships were large enough to carry cargo and passengers on long ocean voyages, but still maintained speed and agility, making the longship a versatile warship and cargo carrier.
Keel, stems and hull[edit | edit source]
The Viking shipbuilders had no written diagrams or standard written design plan. The shipbuilder pictured the longship before its construction, based on previous builds, and the ship was then built from the keel up. The keel and stems were made first. The shape of the stem was based on segments of circles of varying sizes. The keel was an inverted T shape to accept the garboard planks. In the longships the keel was made up of several sections spliced together and fastened with treenails. The next step was building the strakes – the lines of planks joined endwise from stern to stern. Nearly all longships were clinker (also known as lapstrake) built, meaning that each hull plank overlapped the next. Each plank was hewn from an oak tree so that the finished plank was about 25 millimetres (0.98 in) thick and tapered along each edge to a thickness of about 20 millimetres (0.79 in). The planks were radially hewn so that the grain is approximately at right angles to the surface of the plank. This provides maximum strength, an even bend and an even rate of expansion and contraction in water. It modern terms this is called quarter sawn timber and has the least natural shrinkage of any cut section of wood. The plank above the turn of the bilge, the meginhufr, was about 37 millimetres (1.5 in) thick on very long ships, but narrower to take the strain of the crossbeams. This was also the area subject to collisions. The planks overlapped by about 25 millimetres (0.98 in)–30 millimetres (1.2 in) and were joined by iron rivets. Each overlap was stuffed with wool or animal hair or sometimes hemp soaked in pine tar to ensure water tightness. At midlength, where the planks are straight, the rivets are about 170 millimetres (6.7 in) apart but were closer together as the planks sweep up to the curved bow and stern. There is considerable twist and bend in the end planks. This was achieved by using both thinner (by 50%) and narrower planks. In more sophisticated builds, forward planks were cut from natural curved trees called reaction wood. Planks were installed unseasoned or wet. Partly worked stems and sterns have been located in bogs. It has been suggested they were stored there over winter to stop the wood drying and cracking. The moisture in wet planks allowed the builder to force the planks into a more acute bend if need be. Once dry it would stay in the forced position. At the bow and the stern builders were able to create hollow sections, or compound bends, at the waterline making the entry point very fine. In less sophisticated ships short and nearly straight planks were used at the bow and stern. Where long timber was not available, or the ship was very long, the planks were butt joined although over lapping scarf joints, fixed with nails.
As the planks reached the desired height, the interior frame (futtocks) and cross beams were added. Frames were placed close together which is an enduring feature of thin planked ships,still used today on some lightweight wooden racing craft such as those designed by Bruce Farr. Viking boat builders used a spacing of about 850 millimetres (33 in). Part of the reason for this spacing was to achieve the correct distance between rowing stations and to create space for the chests used by Norse sailors as thwarts (seats). The bottom futtocks next to the keel were made from natural L-shaped crooks. The upper futtocks were usually not attached to the lower futtocks to allow some hull twist. The parts were held together with iron rivets, hammered in from the outside of the hull and fastened from the inside with a rove (washers). The surplus rivet was then cut off. A ship normally used about 700 kilograms (1,500 lb) of iron nails in a 18 metres (59 ft) long ship. In some ships the gap between the lower uneven futtock and the lapstrake planks was filled with a spacer block about 200 millimetres (7.9 in) long. In later ships spruce stringers were fastened lengthwise to the futtocks roughly parallel to the keel. Longships had about five rivets for each yard (90 centimetres (35 in)) of plank. In many early ships treenails (trenails, trunnels) were used to fasten large timbers. First, a hole about 20 millimetres (0.79 in) wide hole was drilled through two adjoining timbers, a wooden pegs inserted which was split and a thin wedge inserted to expand the peg. Some treenails have been found with traces of linseed oil suggesting that treenails were soaked before the pegs were inserted. When dried the oil would act as a semi waterproof weak filler/glue.
The longships’ narrow deep keel provided strength beneath the waterline. A typical size keel of a longer ship was 100 millimetres (3.9 in)×300 millimetres (12 in) amidships, tapering in width at the bow and stern. Sometimes there was a false outer keel to take the wear while being dragged up a beach. These large timbers were shaped with both adze and broadaxe. At the bow the cut water was especially strong, as longboats sailed in ice strewn water in spring. Hulls up to 560 centimetres (18.4 ft) wide gave stability, making the longship less likely to tip when sailed. The greater beam provided more moment of leverage by placing the crew or any other mobile weight on the windward side. Ocean going longships had higher topsides about a 1 metre (3.3 ft) high to keep out water. Higher topsides were supported with knees with the long axis fastened to the top of the crossbeams. The hull was waterproofed with animal hair, wool, hemp or moss drenched in pine tar. In the autumn the ships would be tarred and then left in a boathouse over the winter to allow time for the tar to dry. To keep the sea out, wooden disks were put into the oar holes. These could be shut from the inside when the oars were not in use. A drain plug hole about 25 millimetres (0.98 in) was drilled in the garboard plank on one side to allow rain water drainage. The oars did not use rowlocks or thole pins but square holes cut below the gunwale line. The holes were also used for belaying mooring lines and sail sheets. At the bow the forward upper futtock protruded about 400 millimetres (16 in) above the sheerline and was carved to retain anchor or mooring lines.
Timber[edit | edit source]
Analysis of timber samples from Viking long boats shows that a variety of timbers were used, but there was strong preference for oak which was associated with Odin in Viking mythology. Oak is a heavy, durable timber that can be easily worked by adze and axe when green (wet/unseasoned). Generally large and prestigious ships were made from oak. Other timber used were ash, elm, pine, spruce and larch. Spruce is light and seems to have been more common in later designs for internal hull battens (stringers). Although it is used for spars in modern times there is as yet no evidence the Vikings used spruce for masts. All timber was used unseasoned. The bark was removed by a bark spade. This consisted of a 1.2 m long wooden handle with a T crossbar at the upper end, fitted with a broad chisel-like cutting edge of iron. The cutting edge was 60 mm wide × 80 mm long with a 120 mm long neck where the handle was inserted. It appears that in cold winters wood work stopped and partly completed timber work was buried in mud to prevent it drying out. Timber was worked with iron adzes and axes. Most of the smoothing was done with a side axe. Other tools used in woodwork were hammers, wedges, drawknives, planes and saws. Iron saws were probably very rare. The doomsday book in England (1086 AD)records only 13 saws. Possibly these were pit saws and it is uncertain if they were used in longship construction.
Sail and mast[edit | edit source]
Even though no longship sail has been found, accounts verify that longships had square sails. Sails measured perhaps 35 feet (11 m) to 40 feet (12 m) across, and were made of rough wool cloth. Unlike in knarrs, a longship sail was not stitched.
The sail was held in place by the mast which was up to 16 m tall. It base was about 250×180 mm. The mast was supported by a large wooden maststep called a kerling ("Old Woman" in Old Norse) that was semicircular in shape. (Trent) The kerling was made of oak, and about 700 mm wide and up to 6 m long in the larger ships. It usually heavily tapered into a joint with the internal keelson, although keelsons were by no means universal. The kerling lay across two strong frames that ran width-wise above the keel in the centre of the boat. The kerling also had a companion: the "mast fish," a wooden timber above the kerling just below deck height that provided extra help in keeping the mast erect. It was a large wooden bulk of timber about 3 m long with a 1.4 m long slot, facing aft to accommodate the mast as it was raised. This acted as a mechanism to catch and secure the mast before the stays were secured. It was an early form of mast partner but was aligned fore and aft. In later longships there is no mast fish-the mast partner is an athwartwise beam similar to more modern construction. Most masts were about half the length of the ship so that it did not project beyond the hull when unstepped. When lowered the mast foot was kept in the base of the mast step and the top of the mast secured in a natural wooden crook about 1.5 m-2.5 m high, on the port side, so that it did not interfere with steering on the starboard side.
There is a suggestion that the rig was sometimes used in a lateen style with the top cross spar dipped at an angle to aid sailing to windward i.e. the spar became the luff. There is little or no evidence to support this theory. No explanation is offered as to how this could be accomplished with a square sail as the lower reefed portion of the sail would be very bulky and would prevent even an approximation of the laminar flow necessary for windward sailing. There is no evidence of any triangular sails in use. Masts were held erect by side stays and possibly fore and aft stays. Each side stay was fitted at it lower end with a 150 mm long toggle. There were no chain plates. The lower part of the side stay consisted of ropes looped under the end of a knee of upper futtock which had a hole underneath. The lower part of the stay was about 500-800 mmm long and attached to a combined flat wooden turnblock and multi V jamb cleat called an angel (maiden, virgin). About 4 turns of rope went between the angel and the toggle to give the mechanical advantage to tighten the side stays. At each turn the v shape at the bottom of the angels "wings" jambed the stay preventing slippage and movement.
Rudder[edit | edit source]
Early long boats used some form of steering oar but by the 10th century the side rudder (called a steerboard, which is why that side of the vessel is now called starboard) was well established. It consisted of a length of timber about 2.4 m long. The upper section was rounded to a diameter of about 150 mm. The lower blade was about 1.8 m x 400 mm. Since there is only a single steerboard, drag from that would make the ship steer a point or too to that side, so the shipwrights created a hydrofoil. Just like an airfoil, movement through fluid creates lift, which perfectly compensates for the offset drag. The steerboard on the Gokstad ship in the Viking Ship Museum in Oslo, Norway, is about 8 inches wide, completely flat inboard and with about a 3" maximum width at the center of the foil. The head of the rudder shaft had two square holes about 200–300 mm apart. When the rudder was in its normal position the tiller was inserted in the upper hole so that the tiller faced athwartwise. The shaft was attached to the gunwale by a U shaped joint. Near the stern, about halfway down the starboard topsides, was a rounded wooden block about 150 mm in diameter and 100 mm high, with a central hole for a rope. This corresponded to a hole in the midsection of the rudder blade. From the outside the rope ran through the blade, through the round block and topsides and was fastened inside the hull. The flexibility of the hemp rope allowed the blade to pivot. When beached or in shallow water the tiller was moved to the lower hole, the blade rope was slackened and the rudder head pulled up so the rudder could operate in shallow waters. Modern facsimiles are reported to steer quite well but require a very large amount of physical effort compared to the modern fore and aft tiller.
Anchors[edit | edit source]
Longships used two different kinds of anchors. The most common was a natural wood yoke formed from a tree branch. The weight was supplied by a stone passing laterally through the U of the yoke. The top of the yolk was closed by either a length of hardwood or a curved iron head, which kept the stone in place. One side of the head stuck out so it could dig into mud or sand. In Denmark an iron Viking age anchor has been found that resembles the modern fisherman's anchor but without the crossbar. The cross bar may have rusted away. These anchors had an iron ring to which the hemp warp was attached.
Ship builders toolkit[edit | edit source]
At the height of Viking expansion into Dublin and Jorvik 875−954 AD the longship reached a peak of development such as the Gokstad ship 890. Archaeological discoveries from this period at Coppergate, York, show the shipwright had a large range of sophisticated woodwork tools. As well as the heavy adze, broad axe, wooden mallets and wedges, the craftsman had steel tools such as anvils, files, snips, awls, augers, gouges, draw knife, knives, including folding knives, chisels and small 300 mm long bow saws with antler handles. Edged tools were kept sharp with sharpening stones from Norway. One of the most sophisticated tools was a 25 mm diameter twist drill bit, perfect for drilling hole for treenails. Simple mechanical pole wood lathes were used to make cups and bowls.
Replica longships[edit | edit source]
Since the discovery of the original longships in the 1800s, many boat builders have built many replicas. However, most have not been able to resist the temptation to use more modern techniques and tools in construction. In 1892−93 a full-size near-replica of the Gokstad ship, the Viking, was built by the Norwegian Magnus Andersen in Bergen. It was used to sail the Atlantic. It had a deeper keel with 1.5m draught to stiffen the hull and a range of non-authentic triangular sails to help performance and big fenders on each gunwale filled with reindeer hair to give extra buoyancy in case of swamping. The skipper recorded that the keel bowed upwards as much as 20mm and the gunwale flexed inwards as much as 150 mm in heavy seas. A half-size replica of the Sutton Hoo longship has been equipped with a substantial sail, despite the original having oar power only.
[edit | edit source]
[edit | edit source]
The Vikings were experts in judging speed and wind direction, and in knowing the current and when to expect high and low tides. Viking navigational techniques are not well understood, but historians postulate that the Vikings probably had some sort of primitive astrolabe and used the stars to plot their course.
The Danish archaeologist Thorkild Ramskou suggested in 1967 that the "sun-stones" referred to in some sagas might have been natural crystals capable of polarizing skylight. The mineral cordierite occurring in Norway has the local name "Viking's Compass." Its changes in colour would allow determining the sun's position (azimuth) even through an overcast or foggy horizon.
An ingenious navigation method is detailed in Viking Navigation Using the Sunstone, Polarized Light and the Horizon Board by Leif K. Karlsen. To derive a course to steer relative to the sun direction, he uses a sun-stone (Solarsteinn) made of Iceland spar (optical calcite or Silfurberg), and a "horizon-board." The author constructed the latter from an Icelandic saga source, and describes an experiment performed to determine its accuracy. Karlsen also discusses why on North Atlantic trips the Vikings might have preferred to navigate by the sun rather than by stars. (Think high latitudes in summer: long days, short to no nights.)
A Viking named Stjerner Oddi compiled a chart showing the direction of sunrise and sunset, which enabled navigators to sail longships from place to place with ease. Almgren, an earlier Viking, told of another method: "All the measurements of angles were made with what was called a 'half wheel' (a kind of half sun-diameter which corresponds to about sixteen minutes of arc). This was something that was known to every skipper at that time, or to the long-voyage pilot or kendtmand ('man who knows the way') who sometimes went along on voyages... When the sun was in the sky, it was not, therefore, difficult to find the four points of the compass, and determining latitude did not cause any problems either." (Algrem)
Birds provided a helpful guide to finding land. A Viking legend states that Vikings used to take caged crows aboard ships and let them loose if they got lost. The crows would instinctively head for land, giving the sailors a course to steer.
Archaeologists have found two devices which they interpret as navigation instruments. Both appear to be sundials with gnomon curves etched on a flat surface. The devices are small enough to be held in the hand at 70 mm diameter. A wooden version dated to about 1000 AD was found in Greenland. A stone version was also found at Vatnahverfi, Greenland. By looking at the place where the shadow from the rod falls on a carved curve, a navigator is able to sail along a line of latitude. Both gnomon curve devices show the curve for 60° north very prominently. This was the approximate latitude that the Vikings would have sailed along to get to Greenland from Scandinavia. The wooden device also has north marked and had 32 arrow heads around the edge that may be the points of a compass. Other lines are interpreted as the solstice and equinox curves. The device was tested successfully, as a sun compass, during a 1984 reenactment when a longship sailed across the North Atlantic. It was accurate to within ± 5°.
Propulsion[edit | edit source]
The longships had two methods of propulsion: oars and sail. At sea, the sail enabled longships to travel faster than by oar and to cover long distances overseas with far less manual effort. Sails could be raised or lowered quickly. Oars were used when near the coast or in a river, to gain speed quickly, and when there was an adverse (or insufficient) wind. In combat, the variability of wind power made rowing the chief means of propulsion. The ship was steered by a long flat oar with a short round handle, mounted over the starboard side of the aft gunwale.
Longships were not fitted with benches. When rowing, the crew sat on sea chests (chests containing their personal possessions) that would otherwise take up space. The chests were made the same size and were the perfect height for a Viking to sit on and row. Longships had hooks for oars to fit into, but smaller oars were also used, with crooks or bends to be used as oarlocks. If there were no holes then a loop of rope kept the oars in place.
An innovation that improved the sail's performance was the beitass, or stretching pole – a wooden spar stiffening the sail. The windward performance of the ship was poor by modern standards as there was no centreboard, deep keel or leeboard. To assist in tacking the beitasss kept the luff taunt. Bracing lines were attached to the luff and lead through holes on the forward gunwale. Such holes were often reinforced with short sections of timber about 500 mm to 700 mm long on the outside of the hull.
Legacy[edit | edit source]
The Vikings were major contributors to the shipbuilding technology of their day. Their shipbuilding methods spread through extensive contact with other cultures, and ships from the 11th and 12th centuries are known to borrow many of the longships’ design features, despite the passing of many centuries. The Lancha Poveira, a boat from Póvoa de Varzim, Portugal is one of the last remnants from the longship, keeping all the longboat features but without a long stern and bow, and with a Mediterranean sail. It was used until the 1950s. Today there is just one boat: Fé em Deus.
Many historians, archaeologists and adventurers have reconstructed longships in an attempt to understand how they worked. These re-creators have been able to identify many of the advances that the Vikings implemented in order to make the longship a superior vessel. One replica longship covered 223 nautical miles (413 km) in a single day, and another re-creator was able to go faster than 8 knots (15 km/h) in his longship.
The longship was a master of all trades. It was wide and stable, yet light, fast, and nimble. With all these qualities combined in one ship, the longship was unrivaled for centuries, until the arrival of the great cog.
In Scandinavia, the longship was the usual vessel for war even with the introduction of cogs in the 12th–13th centuries. Leidang fleet-levy laws remained in place for most of the Middle Ages, demanding that the freemen should build, man and furnish ships for war if demanded by the king—ships with at least 20 or 25 oar-pairs (40–50+ rowers). However, by the late 14th century, these low-boarded vessels were at a disadvantage against newer, taller vessels – when the Victual Brothers, in the employee of the Hansa, attacked Bergen in the autumn of 1393, the "great ships" of the pirates could not be boarded by the Norwegian levy ships called out by Margaret I of Denmark and the raiders were able to sack the town with impunity. While earlier times had seen larger and taller longships in service, by this time the authorities had also gone over to other types of ships for warfare. The last Viking longship was defeated in 1429.
Famous longships[edit | edit source]
- The Oseberg ship and the Gokstad ship – both from Vestfold in Norway.
- The Ormen Lange ("The Long Serpent") was the most famous longship of Norwegian king Olaf Tryggvason.
