cog ship crew size

Cogs were characterized by a flush-laid flat bottom at midships but gradually shifted to overlapped strakes near the posts. They had a full clinker planking covering the ides and double-clenched iron nails for the planks. Cogs were a type of round ship,[1] characterized by a flush-laid flat bottom at midships which gradually shifted to overlapped strakes near the posts. COG typical dimensions: Tonnage: 140 t Crew: 28 men Hull length: 20 m Width: 7 m Draught: 3 m Cog on Paris Crest (1390) Northern Cog. Cogs could carry more cargo than knarrs; the rudder made steering easier than did the steering oar of the knarr, especially for larger vessels; and cogs were cheaper to build. Both stem and stern posts were straight and rather long, and connected to the keelplank through intermediate pieces called hooks. The size of this sail was dependent on the size of the hull. The size of the ships is determined the role it will play. The new strake is held in position on the preceding one before the fastening is done. Later, as cogs were used for sailing through the rough waters of North Atlantic, their hull were made from clinker construction, which used to provide them with added strength and robustness. The lower plank hoods terminated in rabbets in the hooks and posts, but upper hoods were nailed to the exterior faces of the posts. Hold Capacity: 50916 volumeunits (67 rafts). This means that as the size of cog hull became bigger the size of sails also increased. In ship: 17th-century developments …by another Venetian ship, the cog. The larger ships, which could not be pulled across the sand bars, had to sail around the Jutland peninsula and circumnavigate the dangerous Cape Skagen to get to the Baltic. [8] The cog-built structure would be completed with a stern-mounted, hanging, central rudder on a heavy stern-post, which was a uniquely northern development. A limitation of cogs is that they lack points to mount additional masts: at least some fore-and-aft sails are desirable for manoeuvrability but clinker-built cogs were effectively limited to a single sail. Developed by the ship builders of Northern Europe, cogs were extensively used in the Baltic Sea region. The classic cog, with a rear-mounted rudder, is first mentioned in 948 AD. A 15,000-TEU ship has a crew just as big as a 20,000-TEU ship. Typical seagoing cogs ranged from about 15 to 25 meters (49 to 82 ft) in length, with a beam of 5 to 8 meters (16 to 26 ft) and were 30–200 tons burthen. Another type of ship, the cog, derived from a barge-style fat-bottomed boat, developed in response to the need for merchant vessels able to transport bulkier loads. Its most distinguishing feature are sails divided into a number of horizontal panels by bamboo slats (battens). Hello sir thanks for a great article. This was the hulk, which already existed but was much less common than the cog. Fuel costs are not very different. The best archaeological example of the longship is the Gokstad ship, a reconstruction of the longship displayed in an Oslo museum. [13] Cordage was usually hemp or flax[note 1] and the sail hemp-based canvas. Cogs progressively replaced Viking-type ships in northern waters during the 13th century. Avg. The habitable volume is 388 cubic meters (13,696 cubic feet). The purpose of a ship is decided at the very first stage of its building process. This is somewhat less than the 20 men which a Cog usually carries when used as a sailing ship, but unlike many groundling ships, it is actually capable of carrying its full groundling … Chinese ships also developped many other features before the west, for example: the stern mounted rudder, multiple masts, water-tight hull sections and the magnetic compass. [23], The most famous cog in existence today is the Bremen cog. Minimum Crew is the bare minimum number of personnel required to operate the vessel with only basic functions (i.e., assuming no modules fitted).. It has square sails on its two masts and can make sea voyages. It was 85 ft (26 m) long at the keel and 20 ft (6 m) across the beam. A large cog may have looked like this. It could be either square rigged and lateen rigged (Caravela Redonda) or only lateen rigged (Caravela Latina).The most famous examples of caravels were the Niña and the Pinta. Economical, defensively and also designed for low tide Larger loads could be transported more cheaply and by a smaller crew than previously. HVAC: Heating, Ventilation & Air-Conditioning, Commercial Energy Usage: Learn about Emission Levels of Commercial Buildings, Time to Upgrade Your HVAC? This allows the end of the strake to be fastened to the apron with the outside of the planking mutually flush at that point and flush with the stem. These give the sail better aerodynamics and allow reducing the sail area for different wind conditions. Basic Statistics Size Most ships are Large, Huge, or Gargantuan. But the end is in sight, these ultra-large ships can only call at a few ports; deployment flexibility is lost. A medium difficulty ship, the cog requires fewer sails but more wooden materials than the corbita and is harder to create. The crew of a square-sailed cog of the same size was only 20 sailors. The size of this sail was dependent on the size of the hull. At the stem, chases are formed; that is, in each case, the land of the lower strake is tapered to a feather edge at the end of the strake where it meets the stem or stern-post. [8][9], The keel, or keelplank, was only slightly thicker than the adjacent garboards and had no rabbet. A large cog may have looked like this. [16] A structural benefit of clinker construction is that it produces a vessel that can safely twist and flex around its long axis (running from bow to stern), which is an advantage in North Atlantic rollers, provided the vessel has a small overall displacement. [10] The single, thick, mast was set forward of amidships, stepped into the keelplank and equipped with a single large, rectangular, square-rigged sail. [26][27], Type of cargo ship of the 12th–14th centuries, Cross-section of hull; note the lower mast stepped and braced, Other materials were also used, for example, In contrast, Mediterranean-type ships built contemporaneously in the French royal, "Excavation, recovery and conservation of a 15th century Cog from the river IJssel near Kampen", "Medieval Shipwreck Hauled from the Deep", International Journal of Nautical Archaeology, The sailing properties of the Hanse cog in comparison with other cargo sailships, https://en.wikipedia.org/w/index.php?title=Cog_(ship)&oldid=992325367, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 4 December 2020, at 17:56. It all depends on the size of the vessel, its equipment, and the cargo its designed to carry. We have been learning about various types of ancient ships and boats in the past few articles and have looked at bark boats, coracles, rafts and dugouts. We build a simple model using the cruise_ship_info.csv data set for predicting a ship's crew size. Construction costs are almost the same. Sounds spacious, but it isn’t. The stern was rounded and the main deck was large to support a large crew and appropriate cannon armament. Their flat bottoms allowed them to settle on a level in harbour, making them easier to load and unload. They were mostly associated with seagoing trade in north-west medieval Europe, especially the Hanseatic League. All Rights Reserved. ːlongshipː In case you were wondering what the stats are for each ship.ːlongshipː Type / Speed / Max Crew / Approximate New Price for Oak Byrding / 9 / 7 / 7500 Knorr / 7 / 11 / 8500 Snekkja / 17 / 27 / 21000 Karvi / 12 / 39 / 23000 Skeid / 20 / 55 / 34000 Busse / 16 / 90 / 49000 All ships are available in Ash (cheapest), Pine (midrange), and Oak (best). Also, the clinker construction added to the overall strength of the ship, making in more durable. It was this construction of cogs that made them more stable than any other ship type even in the rough seas. The ship's off-duty crew sleep on bedrolls among the crates and barrels of food, water, and other supplies. A sturdy one-masted merchant ship with a flat bottom. Wraith Hive ships are the main component of the Wraith fleet and the centerpiece of their entire society. Caulking was generally tarred moss that was inserted into curved grooves, covered with wooden laths, and secured by metal staples called sintels. The ships … Sounds spacious, but it isn’t. [12] Complicated systems of rigging were developed to support the mast and to operate the sail. 20180712: medieval cog ship sailing down the IJssel river at Kampen. Ship's maximum measurements are defined by the Chinamax standars, allowing ports to determine whether they can accommodate ships in this class. As ships increased in container and bulk capacity, crew size shrank and dramatically so, a typical corporate cost cutting method. Crew: This is the minimum number of crew members needed to move the ship, in addition to the pilot. The keel was thicker than the strake, cogs could also be used to have open hulls and they could have been rowed in short distances if needed. It could bear a load of 120 tons of cargo. The cog was a round ship that had a laid flat bottom but has overlapped strakes near the posts. cruise_ship_info.csv: dataset used for model building. They had full lapstrake planking covering the sides, generally starting from the bilge strakes, and double-clenched iron nails for plank fastenings. Its walls are fitted with built-in weapon and armor racks. Any crew required to operate a ship’s siege engines is in addition to this number. In this article we will study about another interesting type of ship namely a cog ship. Unlike the longship and cog, it used a carvel method of construction. Cogs were a type of round ship, characterized by a flush-laid flat bottom at midships which gradually shifted to overlapped strakes near the posts. Cogs were clinker-built, generally of oak. for example a ship spesification has a capacty of 18,470 TEU and a DWT of 165,000 tonne. However, their simpler sail setup meant that cogs only required half the crew of similar sized vessels equipped with lateen sails, as were common in the Mediterranean. [11][9] The masts of larger vessels would be of composite construction. [14] From the 13th century cogs would be decked, and larger vessels would be fitted with a stern castle, to afford more cargo space by keeping the crew and tiller up, out of the way; and to give the helmsman a better view. Mediterranean Cog. These early cogs were influenced by the Norse knarr, which was the main trade vessel in northern Europe at the time, which used a steering oar. Chinamax. They were propelled by a single, large, rectangular sail. Chinamax ships are very large bulk carrier which can't be longer than 360m (1,180 ft), wider than 65 m (213 ft) and her draft can't be more than 24 m (79 ft). They are also used to attack other players. Crew size ranged from a minimum of seven to fifteen and could carry up to a maximum of 30 to 50, including passengers. Cogs were rarely as large as 300 tons, although a very small number were considerably larger, over 1,000 tons. This caused a boom in the number of small cogs, and the need for spacious and seaworthy ships led to the development of the cog as the workhorse of the Hanseatic League. A caravel could be armed with a large weapon (such as a catapult or ballista) but was not built to wield a ram. The north has had no strength at sea since King in the North Brandon the Burner put Brandon the … This varies all along the land. [17][18] This made them unhandy, limiting their ability to tack in harbour and making them very reliant on wind direction at the start of voyages. Typical of Viking raiding vessels, she is 76 ′ long. It moves about 2 miles per hour. [20] The stern castle also afforded more cargo space below by keeping the crew and tiller up, out of the way. Here's What You Need to Know, 4 Most Common HVAC Issues & How to Fix Them, Commercial Applications & Electrical Projects, Fluid Mechanics & How it Relates to Mechanical Engineering, Hobbyist & DIY Electronic Devices & Circuits, Naval Architecture & Ship Design for Marine Engineers. Overall the ISS is larger than a six bedroom house with 6 crew, or 152 cubic meters per person. Ships are loaded at warehouses, harbormaster offices, and piers. www.stradbrokeislandgalleon.com/ship_cog.jpg, Unigraphics Tutorial – Learn UG NX6 Variational Sweep. This is why each new generation of container ships breaks the size record every time. This change produced new challenges. China is not know… Current archaeological evidence points to the Frisian coast or Western Jutland as the possible birthplace of this type of vessel. For centuries, the Limfjord in northern Jutland offered a fairly protected passage between the North Sea and the Baltic. Typical seagoing cogs ranged from about 15 to 25 meters (49 to 82 ft) in length with a beam of 5 to 8 meters (16 to 26 ft) and were 40–200 tons burthen. The cog was a round ship that had a laid flat bottom but has overlapped strakes near the posts. [15] Fore and stern castles would be added for defense against pirates, or to enable the use of these vessels as warships. A rule of thumb for crewsize was that one sailor… Generally built from oak wood, cogs had only a single long mast which carried a massive square sail. This means that the boat's passage through the water will not tend to lift the ends of the planking away from the stem. The stern and stern posts are both straight in shape and are attached to the keel plate by means of hooks. The deadweight tonnage of these vessels is 380,000–400,000 DWT. Cogs progressively replaced Viking-type ships in Northern waters during the 13th century. Also as cogs were made to carry huge amount of cargo they featured a very large hull. The ships … An “average” 5,500 to 8000 TEU container ship has a crew of only 20 – 30. Warship This 100-foot-long ship has a single mast, although oars can also propel it. A ship’s size category is determined by its length or width, whichever is longer. [21] This resulted in major modifications to old ship structures, which can be observed by analyzing the evolution of the earliest cog finds of Kollerup, Skagen, and Kolding. This equates to about 2.1 cubic meters of livable space per tonne. Moreover, the early cogs were not large and had open hulls with very less continuous sailing capability. Although the name cog is recorded as early as the 9th century, the seagoing vessel of that name seems to have evolved on the Frisian coast during the 12th century. In addition, there are special sockets that can hold special items which can improve the pa… It was produced relatively quickly and inexpensively at that time. It dates from the 1380s and was found in 1962; until then, cogs had only been known from medieval documents and seals. Cogs are spacious ships with only one large mast that holds a single square sail. A buss of 240 tons with lateen sails was required by maritime statutes of Venice to be manned by a crew of 50 sailors. [15] The latter was due to the cog's use of sawn, rather than split, timber. Cogs were single-masted vessels, clinker-built with steep sides and a flat bottom . It all depends on the size of the vessel, its equipment, and the cargo its designed to carry. each container has a supposdly max weight of 30,000kg (30ton). Number of crew on any merchant tanker is determined by various factors - most importantly the 'Minimum Safe Manning' certificate and type of trade the tanker is used for. Although other scholars, such as Jan Bill, have challenged this hypothesis, it remains a possibility.7 Height and crew size were crucial advantages in medieval sea warfare, and it is likely that large, castle-equipped sailing ships could only have been defeated, in most cases, by ships … A buss of 240 tons with lateen sails was required by maritime statutes of Venice to be manned by a crew of 50 sailors. If a ship uses muscle propulsion, the number and size of creatures providing the propulsion are listed here as well. In 1990 the well-preserved remains of a Hanseatic cog were discovered in the estuary sediment of the Pärnu River in Estonia which has been dated to 1300. Their high sides made them more difficult to board in a sea fight, which may have made them safer from pirates. Overall the ISS is larger than a six bedroom house with 6 crew, or 152 cubic meters per person. Strong cross-beams, usually protruded through the ship's sides, holding the sides together; 13th century cog illustration. The aftcastle was used for steering and a platform to attack other ships during boarding actions with the use of muskets and small cannonades. They had a full clinker planking covering the ides and double-clenched iron nails for the planks. Typical seagoing cogs ranged from about 15 to 25 meters (49 to 82 ft) in length with a beam of 5 to 8 meters (16 to 26 ft) and were 40–200 tons burthen. Crew. Cog was the first type of boat that used the new idea of a rudder mounted on the stern for steering purpose. When used as a spelljammer, a Cog will typically carry a crew of about a dozen men. The lower plank h… These vessels were fitted with a single mast and a square-rigged single sail. For instance, a ship that is 10 feet long and 20 feet wide would They were propelled by a single, large, rectangular sail. To illustrate the quickly increasing size of the ships we can look at the Hanseatic notes in the Lübecker Zollrolle of 1227. Collier: A vessel designed for the coal trade. The minimum crew size was 10 with a maximum of 25. Although the name cog is recorded as early as the 9th century, the seagoing vessel of that name seems to have evolved on the Frisian coast during the 12th century. Without any effort from its crew, a ship might drift on the water, come to a stop, or careen out of control. [4][note 2]. The plank of the keel is thicker than the lapstrake planking at the sides. Hive ships function in a role similar to that of Ancient City-ships and Traveler generational ships. On both the sides of the keel there is lapstrake planking, firmly fixed by iron nails. The ship's supply of weapons and armor is held in this cabin. It can carry 150 tons of cargo. The keel, or keelplank, was only slightly thicker than the adjacent garboards and had no rabbet. The habitable volume is 388 cubic meters (13,696 cubic feet). 13. A cog could transport a relatively large amount of cargo with just a small crew, up to 90 tons (see also Schiffahrtsmuseum Bremerhaven). The crew of a square-sailed cog of the same size was only 20 sailors. Sailing Ship This larger, seaworthy ship is 75 to 90 feet long and 20 feet wide and has a crew of 20. Description. Even though the clinker construction limited the ultimate size of a cog, Thomas Walsingham speaks of great cogs in 1331 with three decks and over 500 crew and soldiers. In the ancient time, cog ships were used for both carrying cargo and for war purposes. The keel was thicker than the strake, cogs could also be used to have open hulls and they could have been rowed in short distances if needed. Also known as a Cogue. [15], A cog, compared with the carvel-built vessels more traditional in the Mediterranean, was expensive and required specialist shipwrights. The transformation of the cog into a true seagoing trader came not only during the time of the intense trade between West and East, but also as a direct answer to the closure of the western entrance to the Limfjord. One large advantage it has over the similarly-sized corbita is that the second passenger to board is put into the crows nest, giving them a great view of the surrounding area. But this facilitated the yacht to be handled by a small crew, reducing the overall operational cost. Armory. Maximum Capacity is the total number of bodies that can fit comfortably-but-snugly on board, including crew and personnel being transported, but without cargo expansion.. Stat. Smaller container ships – but those larger than cargo vessels might have a crew size … Examples are usually up to 25. [2][3][4][5] A rule of thumb for crew size was that one sailor, exclusive of any dedicated fighting men, was required for every 10 tons burthen of the cog, although this may generate a suggested crew size on the low side of Medieval practice. This would mean the crew size would be something from 20-30. Pressurized volume is 916 cubic meters. TweetShare104SharePin4108 Shares Everyone is astounded by the enormous ship sizes. i want to know however whats the difference between DWT and ship capacty? Each ship has a certain number of cargo holds that can hold items and cargo. The major fleets of Westeros are the Iron Fleet and the fleets of the ironborn lords, based in the Iron Islands; the royal fleet, based at King's Landing and Dragonstone; and the Redwyne fleet, based at the Arbor. [10] The transition from cogs to hulks was not linear, according to some interpretations both vessels coexisted for many centuries but followed diverse lines of evolution. This project is organized as follows: (a) data proprocessing and variable selection; (b) basic regression model; (c) hyper-parameters tuning; and (d) techniques for dimensionality reduction. [7], Cogs were typically constructed largely of oak, and had full lapstrake, or clinker, planking covering their sides, generally starting from the bilge strakes, with double-clenched iron nails for plank fastenings. [17][19] The flat bottom permitted cogs to be readily beached and unloaded at low tide when quays were not available; a useful trait when purpose built jetties were not common. [11] Cogs were expected to have a working life of approximately 40 years. Cogs were rarely as large as 300 tons, although a very small number were considerably larger, over 1,000 tons. Weight(kg) has no effect on this. [6] Crews of up to 45 for civilian cogs are recorded, and 60 for a 240 ton cog being used for military transportation. [18][22], Eventually, around the 14th century, the cog reached its structural limits, and larger or more seaworthy vessels needed to be of a different type. This means that as the size of cog hull became bigger the size of sails also increased. The door to this cabin is usually locked, the key kept by one of the ship's … However, the only drawback of this construction was that it prevented sailing directly into the wind. The Venetian buss was rapidly supplanted by another Venetian ship, the cog. [21] It soon became the main cargo carrier in Atlantic and Baltic waters. The best archaeological example of the longship is the Gokstad ship, a reconstruction of the longship displayed in an Oslo museum. Pressurized volume is 916 cubic meters. Cogs were rarely as large as 300 tons although a few were considerably larger, over 1,000 tons. The forecastle was used for defense and tended to make navigation somewhat difficult. It usually had only one deck and could be outfitted with fore- and sterncastles. Based on these variables a ship … However, the earliest cogs didn’t use the stern rudders but has steering oars which were also known as side rudders. Cogs are ships with flat bottom, which had a ridge or keel that runs along the bottom of the ship. The required crew size will be dictated by a document called the Minimum Safe Manning Certificate. Due to its unusual geographical conditions and strong currents, the passage was constantly filling with sand and was completely blocked by the early 12th century. Cogs were large sailing ships with their bows and sterns built at a higher level than the rest of the ship in order to form a castle like structure which was used to defend the ship from enemies using archers. To illustrate the quickly increasing size of the ships we can look at the Hanseatic notes in the Lübecker Zollrolle of 1227. The base cargo size is 40 tons per hold. The caravel was a ship developed by the Portuguese and used from the 15th century on for oceanic exploration voyages. Before the next plank is fitted, the face of the land on the lower strake is bevelled to suit the angle at which the next strake will lie in relation with it. There is no evidence that hulks descended from cogs, but it is clear that a lot of technological ideas were adapted between the two types. A cog ship refers to one of those ships that were invented in the middle ages. Why this was the case is uncertain, but cogs could carry more cargo than knarr of a similar size. They are used to carry goods, special items, and people between islands. This equates to about 2.1 cubic meters of livable space per tonne. Typical of Viking raiding vessels, she is 76 ′ long. Copyright © 2020 Bright Hub PM. Its design, size, and areas of operation are decided too. The typical vessel is the junk, an efficient design that is fast, easy to handle and able to sail upwind. Strong cross-beams, usually protruded through the ship's sides, holding the sides together; 13th century cog illustration. A cog is characterised by high sides, a relatively flat bottom, rounded bilge and a single square sail. [24] In 2012, a cog dating from the early 15th century was discovered preserved from the keel up to the decks in the silt of the River IJssel in the city of Kampen, Netherlands. The crew usually consisted from: the captain, who would be either the merchant selling his wares who rented a ship, or the shipowner himself, or most common a fidalgo (minor nobleman) in service of the ship owner or whoever organized the expedition. Ships are an essential element in Anno 1404. However, the only drawback of this construction was that it prevented sailing directly into the wind. [25] During its excavation and recovery an intact brick dome oven and glazed tiles were found in the galley as well as a number of other artifacts. Crew Guidelines. A cog is a type of ship that first appeared in the 10th century, and was widely used from around the 12th century on. The required crew size will be dictated by a document called the Minimum Safe Manning Certificate. Both stem and stern-posts were straight and rather long, and connected to the keelplank through intermediate pieces called hooks. Moreover, the stern mounted central rudder is an integral part of the cog construction. It was capable of carrying one large weapon (such as a catapult or ballista) but was not built to wield a ram.
