, which would be disastrous for Swedish interests.
Until the early 17th century, the Swedish navy comprised primarily smaller single-decker ships with relatively light guns; these ships were cheaper than larger ships and were well-suited for escort and patrol. For both tactical and economic reasons, the single-deckers were more suited to the Baltic environment, and were generally favored by the privy council and senior officers. However, a fleet of large ships was considered a bold statement and an effective way to impose respect on enemies and allies alike, possibly even beyond the Baltic. For the ambitious Gustavus Adolphus, a navy with a core of powerful capital ship

s was an opportunity that could not be missed. Vasa was the first in a series of five ships intended to be among the heaviest and most splendid of their time. The four other ships, Äpplet, Kronan, Scepter and Göta Ark, were successful and formed the backbone of the Swedish navy until the 1660s. Of these so-called regalskepp (usually translated as "royal ships"), Vasa was meant to be the grandest. The second of the large ships, Äpplet ("The Apple"; the Swedish term for the globus cruciger

), was built simultaneously with Vasa. The only difference between the design of the "Vasa" and its sister ship the "Apple" was that the "Apple" was a mere 1.5 meters (5 ft) wider.

Construction

Just before Vasa was ordered, work at the Stockholm shipyard was led by Antonius Monier, with Dutch-born Henrik Hybertsson

 lost 10 ships in a single storm, and the king sent a worried letter to Admiral Klas Fleming

, asking him to make sure that Henrik hurried the construction of the two smaller ships. Along with the letter, the king sent measurements for the ship, which was to have a keel of 37 meters (120 ft). That gave Henrik Hybertsson new problems, because the measurements ordered by the king fell between those of the larger and smaller vessels in the original contract, and the timber had already been cut. In a new letter, on 22 February 1626, the king again demanded that his measurements for the new ship be followed. Hybertsson never saw Vasa completed; he fell ill in late 1625, one year into construction, and died in the spring of 1627. The supervision of the shipbuilding was given to Hybertsson's assistant, Henrik 'Hein' Jacobsson, also a Dutch immigrant.

Vasa's hull was complete enough to be launched in 1627, probably during the spring. After this, work most likely began on finishing the upper deck, the sterncastle, the beakhead

. The king visited the shipyard in January 1628 and made what was probably his only visit aboard the ship.
In the summer of 1628, the captain responsible for supervising construction of the ship, Söfring Hansson, arranged for the ship’s stability to be demonstrated for the Vice Admiral responsible for procurement, Klas Fleming, who had recently arrived in Stockholm from Prussia. Thirty men ran back and forth across the upper deck to start the ship rolling, but the admiral stopped the test after they had made only three trips, as he feared the ship would capsize. According to testimony by the ship’s master, Göran Mattson, Fleming remarked that he wished the king were at home. Gustavus Adolphus had been sending a steady stream of letters insisting that the ship put to sea as soon as possible.

There has been much speculation that Vasa was lengthened during construction and whether an additional gun deck was added late during the build or not. Little evidence suggests that Vasa was substantially modified after the keel was laid. Ships contemporary to Vasa that were elongated were cut in half and new timbers spliced between the existing sections, making the addition readily identifiable, but no such addition can be identified in the hull. Claims about the addition of a second gun deck are harder to refute, but significant evidence exists against it. The king ordered 72 24-pound cannons for the ship on 5 August 1626, and this was too many to fit on a single gun deck. Since the king's order was issued less than five months after construction started, it would have come early enough for the second deck to be included in the design. The French Galion du Guise, the ship used as a model for Vasa, according to Arendt Hybertsson, also had two gun decks.

Armament

Vasa was built during a time of transition in naval tactics, from an era when boarding was still one of the primary ways of fighting enemy ships to an era of the strictly organized ship-of-the-line and a focus on victory through superior firepower. Vasa was armed with powerful guns and built with a high stern, which would act as a firing platform in boarding actions for some of the 300 soldiers it was supposed to carry. It was neither the largest ship ever built, nor did it have the greatest number of guns. What made it arguably the most powerful warship of the time was the combined weight of shot that could be fired from the cannons of one side: 588 pounds (267 kg). This was the largest concentration of artillery in a single warship at the time, and it was not until the 1630s that a ship with more firepower was built. This large amount of naval artillery was placed on a ship that was quite small relative to the armament carried. By comparison USS Constitution

-tactic, where ships fought in single file (or
line ahead) while the group as a whole attempted to present the batteries of one side toward the enemy. The guns would be aimed in the same direction and fire almost simultaneously. In the 17th century, tactics involving organized formations of several ships had still not been developed. Rather, ships would fight individually or in improvised groups, and focused on boarding. Vasa, though possessing a formidable battery, was built with these tactics in mind, and therefore lacked a unified broadside

 with guns that were all aimed in roughly the same direction. Rather, the guns were intended to be fired independently and were arranged according to the curvature of the hull, meaning that the ship would be bristled with artillery in all directions, covering virtually all angles except straight forward and partial, backwards-facing radii about 45 degrees to either side of the stern..

Naval gunnery in the 17th century was still in its infancy. Guns were expensive and had a much longer lifespan than any warship. Guns with a lifetime of almost a century were not unheard of, and most warships would only be used for 15 to 20 years. In Sweden and in many European countries, a ship would not "own" its guns but would instead be issued armament from the armory for every mission. Ships were therefore mostly fitted with guns of very diverse age and size. What allowed Vasa to carry so much firepower was not merely that an unusually large number of guns were crammed into a relatively small ship but also that all but two of the 48 heavy 24-pounder guns were of a new and standardized lightweight design. (The remaining two were heavier guns of an older design, intended to go in the bows, the so-called bow chasers). All cannons during this time had to be made from individually made casts that could not be reused, but Vasa's guns had such uniform precision in their design that their primary dimensions varied by only a few millimeters, and their bores were almost exactly 146 millimeters (5.7 in). The remaining armament of Vasa consisted of eight 3-pounders, six large caliber howitzer

Ornamentation

As was the custom with warships at the time, Vasa was decorated with sculptures intended to glorify the authority, wisdom and martial prowess of the monarch and also to deride, taunt and intimidate the enemy. The sculptures made up a considerable part of the effort and cost of building the ship and even added considerably to its weight, thereby hampering its maneuverability. The symbolism used in decorating the ship was mostly based on the Renaissance

 Previously, it was believed that the background color had been blue and that all sculptures had been almost entirely gilded, and this is reflected in many paintings of Vasa from the 1970s to the early 90s, such as the lively and dramatic drawings of Björn Landström or the painting by Francis Smitheman. In the late 1990s, this view was revised and the colors are properly reflected in more recent reproductions of the ship's decoration by maritime painter Tim Thompson and the 1:10 scale model in the museum.

Charles IX of Sweden also Carl, was King of Sweden from 1604 until his death. He was the youngest son of King Gustav I of Sweden and his second wife, Margaret Leijonhufvud, brother of Eric XIV and John III of Sweden, and uncle of Sigismund III Vasa king of both Sweden and Poland...

.

A team of at least six expert sculptors worked for a minimum of two years on the sculptures, most likely with the assistance of an unknown number of apprentices and assistants. No direct credit for any of the sculptures has been provided, but the distinct style of one of the most senior artists, Mårten Redtmer, is clearly identifiable. Other accomplished artists, like Hans Clausink, Johan Didrichson Tijsen (or Thessen in Swedish) and possibly Marcus Ledens, are known to have been employed for extensive work at the naval yards at the time Vasa was built, but their respective styles are not distinct enough to associate them directly with any specific sculptures.

The artistic quality of the sculptures varies considerably, and about four distinct styles can be identified. The only artist who has been positively associated with various sculptures is that of Mårten Redtmer, whose style has been described as "powerful, lively and naturalistic" and was responsible for a considerable percentage of the sculptures. These include some of the most important and prestigious pieces: the figurehead lion, the royal coat of arms, and the sculpture of the king at the top of the transom. Two of the other styles are described as "elegant ... a little stereotyped and manneristic", and of a "heavy, leisurely but nevertheless rich and lively style", respectively. The fourth and last style, deemed clearly inferior to the other three, is described as "stiff and ungainly" and was done by other carvers, perhaps even apprentices, of lesser skill.

Maiden voyage

On 10 August 1628, Captain Söfring Hansson ordered Vasa to set sail on its maiden voyage to the naval station at Älvsnabben
Älvsnabben
Älvsnabben is a natural harbor consisting of four small islands Älvsnabben, Bjurshagslandet, Kapellön and Gubbholmen near Muskö in the archipelago north of Stockholm, Sweden.

. The day was calm, and the only wind was a light breeze from the southwest. The ship was towed along the waterfront to the southern side of the harbor, where three sails were set, and the ship made way to the east. The gun ports were open, and the guns were out to fire a salute as the ship left Stockholm.

After
Vasa emerged from the lee of the city, a gust of wind filled its sails, and it heeled suddenly to port. The sheets

 as the gust passed. Soon another gust came, which again forced the ship onto its port side, this time pushing the open lower gun ports under water, causing water to rush in on the lower gun deck. The inflow of water heeled Vasa over further, and it quickly sank to a depth of 32 meters (105 ft) only 120 meters (390 ft) from shore. Survivors clung to debris to save themselves, and many nearby boats rushed to their aid, but despite these efforts and the short distance to land, 30 to 50 people perished with the ship, according to reports. The flags and the tops of the main and fore masts, still visible above the surface, leaned heavily to port because of ballast that had shifted during the sinking. Vasa sank in full view of a crowd of hundreds, if not thousands, of mostly ordinary Stockholmers who had come to see the great ship set sail. The crowd included foreign ambassadors, in effect spies of Gustavus Adolphus' allies and enemies, who also witnessed the catastrophe.

Inquest

The king was notified by letter of
Vasas fate on 27 August. "Imprudence and negligence" must have been the cause, he wrote angrily in his reply, demanding in no uncertain terms that the guilty parties be punished. Captain Söfring Hansson, who survived the disaster, was immediately imprisoned awaiting trial. Under initial interrogation, he swore that the guns had been properly secured and that the crew was sober. A full inquest, organized by a committee, many members of which were also on the privy council, took place before a court of admirals and councilors on 5 September 1628. Each of the surviving officers was questioned as was the supervising shipwright and a number of expert witnesses. Also present at the inquest was the Admiral of the Realm. The object of the inquest was as much or more to find a scapegoat as to find out why the ship had sunk. Whoever the committee might find guilty for the fiasco would face a severe penalty.

Surviving crew members were questioned one by one about the handling of the ship at the time of the disaster. Was it rigged properly for the wind? Was the crew sober? Was the ballast properly stowed? Were the guns properly secured? However, no one was prepared to take the blame. Crewmen and contractors formed two camps; each tried to blame the other, and everyone swore he had done his duty without fault and it was during the inquest that the details of the hushed-up stability test were revealed. Nevertheless, the answers were deemed satisfactory, and no incriminating evidence was found.

Later, the focus was turned on the ship builders. "Why did you build the ship so narrow, so badly and without enough bottom that it capsized?" the shipwright Jacobsson was asked by the investigators. He fell back on the classic strategy of civil servants; he had simply followed orders. Jacobsson stated that he built the ship as directed by Henrik Hybertsson (long since dead and buried), who in turn had followed the instructions of the king. Jacobsson had in fact widened the ship by 42 centimeters (1.38 ft) after taking over the construction, but the ship's construction was too far along to allow further widening.

In the end, no guilty party could be found. The answer Arendt Hybertsson gave when asked by the court why the ship sank was "only God knows". Gustavus Adolphus had approved all measurements and armaments, and the ship was built according to the instructions and loaded with the number of guns specified. In the end, no one was punished or found guilty for negligence, and the sinking was explained as an act of God. The sinking of Vasa was a major economic disaster; the ship's cost was more than 40,000 dalers

, a huge expense for the small Swedish state.

Vasa as a wreck

Less than three days after the disaster, a contract was put out for the ship to be raised. However, those efforts were unsuccessful. The earliest attempts at raising Vasa by English engineer Ian Bulmer resulted in righting the ship somewhat to starboard but also got it more securely stuck in the mud and was most likely one of the biggest impediments to the earliest attempts at recovery. Salvaging technology in the early 17th century was much more primitive than today, but the recovery of ships used roughly the same principles as were used to raise Vasa more than 300 years later. Two ships or hulks were placed parallel to either side above the wreck, and ropes attached to several anchor
Anchor
An anchor is a device, normally made of metal, that is used to connect a vessel to the bed of a body of water to prevent the vessel from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα .Anchors can either be temporary or permanent...

s were sent down and hooked to the ship. The two hulks were filled with as much water as was safe, the ropes tightened, and the water pumped out. The sunken ship then rose with the ships on the surface and could be towed to shallower waters. The process was then repeated until the entire ship was successfully raised above water level. Even if the underwater weight of Vasa was not great, the mud in which it had settled made it sit more secure on the bottom and required considerable lifting power to overcome. More than 30 years after the ship's sinking, in 1664, Albreckt von Treileben and Andreas Peckell mounted an effort to recover the valuable guns. With a simple diving bell

, the team of Swedes and Germans retrieved more than 50 of them.

Such activity waned when it became clear that the ship could not be raised by the technology of the time. However, Vasa did not fall completely into obscurity after the recovery of the guns. The ship was mentioned in several histories of Sweden and the Swedish Navy, but the exact location of the ship and the details surrounding it varied. In 1844, the navy officer Anton Ludwig Fahnehjelm turned in a request for salvaging rights to the ship, claiming he had located it. Fahnehjelm was an inventor who designed an early form of light diving suit and had previously been involved in other salvage operations. No records exist of any major salvage attempts after Fahnehjelm filed his request, and it has been assumed that none was actually made. Recently, a map found in the Stockholm City Museum archives dated to the late 1830s marks the exact location of the ship with the word wrak ("wreck") and a dotted circle as well as detailed depth markings around the wreck site. In 1999, a witness also claimed that his father, a petty officer in the Swedish navy, had partaken in diving exercises down to Vasa in the 1920s.

Deterioration

In the 333 years that Vasa lay on the bottom of Stockholms ström

, the ship and its contents were subject to several destructive forces, first among which were decomposition and erosion. Among the first things to decompose were the thousands of iron bolts that held the beakhead

 and much of the sterncastle in place, and this included all of the ship's wooden sculptures. Almost all of the iron on the ship rusted away within a few years of the sinking, and of the large iron objects like ammunition and cannons almost nothing remained but carbon. This helped preserve the shape of many metal objects, though the actual metal content was negligible. Of the human remains, the soft tissue was quickly consumed by bacteria, fish and crustaceans, leaving only the bones, which were often held together only by clothing. Clothing and leather objects, such as pouches and shoes, were badly worn, but many survived until recovered in the 20th century.

The entire sterncastle, the high, aft portion of the ship that housed the officers' quarters and held up the transom, gradually collapsed into the mud with all the decorative sculptures, and all but minute traces of the paint and gold leaf on the sculptures disappeared. The quarter galleries

, which were merely nailed to the sides of the sterncastle, soon collapsed and were found lying almost directly below their original locations. Many of the wooden elements were also worn by the currents and by the flow of mud sediments, and some sculptural elements were worn so badly that they were only barely recognizable as carvings when recovered.

In addition to deterioration caused by natural forces, the ship suffered many instances of mechanical damage caused by human activity. The more or less successful salvage operations from 1629 to the 1680s had considerable impact on the ship's structure. To recover the cannons, Peckell and Treileben had broken up and removed much of the planking of the weather deck to get to the cannons on the decks below. Peckell also reported that he had recovered 30 cartloads of wood from the ship; these might have included not just planking and structural details but also some of the sculptures which today are missing, such as the life-size Roman warrior near the bow and the sculpture of Septimius Severus

. Since Vasa lay in a busy shipping channel, tons of slag and blasting rubble were dumped on the ship in the 19th century; this caused further collapse of the sterncastle and most of the weather deck. Traces of numerous anchors that had caught on the ship and then wrenched loose by force became evident during the modern excavations.

. The work under the ship was extremely dangerous, requiring the divers to dig by flushing out mud with water sprayed through a nozzle under high pressure. Visibility was practically zero most of the time, and only a few meters in the best of conditions. A persisting risk was that the wreck could shift or settle deeper into the mud while a diver was working in a tunnel, trapping him underneath the wreckage. The almost vertical sections of the tunnels near the side of the hull could also potentially collapse and bury a diver inside. Despite the dangerous conditions, more than 1,300 dives were employed in the salvage

 operation without any serious accidents.

The ship was raised in a series of 18 lifts in August and September 1959, bringing it from a depth of 32 meters (105 ft) to a more easily managed 16 meters (52 ft) in the more sheltered area of Kastellholmsviken, where it was prepared for the final lift during a year and a half. Debris and mud were cleared from the upper decks to lighten it, and it was made as watertight as possible. The gun ports were closed by means of temporary lids; a temporary replacement of the collapsed sterncastle was constructed, and all the holes from the iron bolts that had rusted away were plugged. The first lift began on 8 April 1961, and on the morning of 24 April, Vasa was ready to break the surface for the first time in 333 years. Press from all over the world, television cameras, 400 invited guests on barges and boats, and thousands of spectators on shore watched as the first timbers broke the surface. The ship was then caulked

 to await the archaeological excavation of its interior.

From the end of 1961, Vasa was housed in a temporary structure called Wasavarvet ("The Vasa Shipyard"). The building was very cramped, making it impossible to see the entire ship at once. Visitors could view the ship from just two levels, and the maximum viewing distance was only 5 metres (16.4 ft), which made it difficult for viewers to get an overall view of the ship. In 1981, the Swedish government decided that a permanent building was to be constructed, and a design competition was organized. The ground was broken in 1987, and Vasa was towed to the half-finished Vasa Museum

Archaeology

Vasa posed an unprecedented challenge for archaeologists. Never before had a four-story structure with most of its original contents largely undisturbed been available for excavation. The conditions under which the team had to work added to the difficulties. The ship had to be kept wet in order that it not dry out and crack before it could be properly conserved. Digging had to be performed under a constant drizzle of water and in a sludge-covered mud that could be more than one meter (approximately three feet) deep. In order to establish find locations, the hull was divided into several sections demarcated by the many structural beams, the decking and by a line drawn along the center of the ship from stern to bow. For the most part, the decks were excavated individually, though at times work progressed on more than one deck level simultaneously.

Finds

Vasa had four preserved decks: the upper and lower gun decks, the hold and the orlop

. Because of the constraints of preparing the ship for conservation, the archaeologists had to work quickly, in 13-hour shifts during the first week of excavation. The upper gun deck was greatly disturbed by interference, both from material from the collapsed decking and from contamination from the surrounding environment. Nonetheless, the upper gun deck yielded many interesting finds such as a well-preserved chest of personal belongings including a felt hat, sewing tools, a comb, two pairs of shoes, a shoe last

Causes of sinking

In the 17th century, the design requirements and calculations for building a ship only existed in the head of the shipwright. Scientific theories on vessel design or stability
Ship stability
Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves. Stability calculations focus on the center of gravity and center of buoyancy of vessels and on how these interact....

 had not yet been developed, so important factors like the ship's center of gravity had to be estimated from the builder's experience. The hull of Vasa was divided into three decks and a bottom compartment containing the ballast, which consisted of large, tightly packed stones. Upon salvaging, the ship was found to have an intact hold full of ballast stones. Vasa carried 120 tonnes of ballast, but this was not enough to counter its considerable weight above the water line; even a light squall would have seriously destabilized the ship. Common practice of the time dictated that heavy guns were to be placed on the lower gun deck to decrease the weight on the upper gun deck and improve stability. The armament plans were changed many times during the build to either place 24-pounders on the lower deck along with lighter 12-pounders on the upper deck or 24-pounders on both decks. The gun ports on the upper deck were in fact the correct size for 12-pounders, but in the end the ship was finished with the heavy 24-pounders on both decks, and this may have contributed to poor stability.

Warships of the period, even when properly armed, were highly unstable. A major reason for this was that they were built with high aftercastles to provide a platform for soldiers to fire upon the enemy with small arms. Also, Vasa may have had the additional problem of an upper hull built with thick wale
Wale
A wale is a broad, thick plank around the outside of a wooden ship.The garboard is the wale next to the keel; the gunwale is the top such plank and covers the heads of the timbers between the main and fore drifts....

 planks that were much too heavy. This might have occurred because of inexperience with two-decker ships or because of the possibility of adding even heavier armaments in the future. However, nothing is inherently wrong with the hull form of the ship; it is within the norms of the period. Later designs, for example English ships of equivalent firepower developed after Vasa, used their heaviest guns on the lower decks and lighter ones on any upper decks, where extra weight was most likely to be detrimental to stability and the righting moment of the ship. Inwardly curved topsides, so-called tumblehome

, were also more pronounced on later designs, so as to bring the mass of the guns closer to the center line of the ship, thus increasing stability.

Captain Söfring Hansson sailed the new ship with open gun ports, which was uncommon. Usually, a brand new ship sailed first with closed gun ports to give the captain and crew an idea of how it would handle. Each ship built in the 17th century handled a little differently from every other ship. Finally, Vasa was supposed to head for Älvsnabben, the naval station in the outer archipelago, to take on all of its stores and personnel, and that might have provided more stability.

Conservation

Although Vasa was in surprisingly good condition after 333 years at the bottom of the sea, it would have quickly deteriorated if the hull had been simply allowed to dry. The large bulk of Vasa, over 900 cubic meters (32,000 cu ft) of oak timber, constituted an unprecedented conservation problem. After some debate on how to best preserve the ship, conservation was done using polyethylene glycol

 was heavily polluted until the late 20th century. The highly toxic and hostile environment meant that even the toughest microorganisms that break down wood had difficulty surviving. This, along with the fact that Vasa had been newly built when it sank, contributed to its conservation. Unfortunately, the toxicity of the water also had a negative effect. The sulfide

s reacted with atmospheric oxygen. The stains had a very low pH and were the first indications that the ship contained considerable amounts of sulfuric acid. The salts on the surface of Vasa and objects found in and around it are not a threat themselves (even if the discoloring may be distracting), but if they are from inside the wood, they may expand and crack the planking from inside. This would cause particularly serious damage if it happened to objects made by skilled craftsmen, such as household items or some of the hundreds of carved sculptures. As of 2002, the amount of sulfuric acid in Vasas hull was estimated to be more than 2 tonnes, and more is continually being created. Enough sulfides are present in the ship to produce another 5000 kilograms (11,023.1 lb) of acid at a rate of about 100 kilograms (220.5 lb) per year; this might eventually destroy the ship almost entirely.

 and eventually liquify the wood. Vasa was exposed to acidic water for more than three centuries, and therefore has a relatively low pH. Samples taken from the ship indicate that formic acid is present, and that it could be one of the multiple causes of a suddenly accelerated rate of decomposition.

The museum is constantly monitoring the ship for damage caused by decay or warping of the wood. Ongoing research seeks the best way to preserve the ship for future generations and to analyze the existing material as closely as possible. A current problem is that the old oak

Legacy

Vasa has become a popular and widely recognized symbol for a historical narrative about the Swedish stormaktstiden ("the Great Power-period") in the 17th century, and about the early development of a European nation state. Within the disciplines of history and maritime archaeology

 the wrecks of large warships from the 16th, 17th and 18th centuries have received particularly widespread attention as perceived symbols of a past greatness of the state of Sweden. Among these wrecks, Vasa is the single most well-known example, and has also become recognized internationally, not least through a deliberate use of the ship as a symbol for marketing Sweden abroad. The name Vasa itself has in Sweden become synonymous with sunken vessels that are considered to be of great historical importance, and these are usually described, explained and valued in relation to Vasa itself. The Swedish maritime archaeologist Carl-Olof Cederlund, who has been active in the various Vasa-projects, has described the phenomenon as regalskepps-syndromet, "the royal ship syndrome" (after the archaic term used for the largest warships named after the regalia

 in the Western world in general. Cederlund has stressed the ritualized aspects of the widely publicized salvage in 1961 and has compared the modern Vasa Museum with "a temple in the Classical sense of the word". The placement of the museum on Djurgården, traditional crown property, and it's focus on "the King's ship" has lead him to suggest a description of it as "The Temple of the Royal Ship".

Literature and popular culture

Vasa has been the subject of hundreds of books, articles and papers on topics ranging from marine archaeology to culinary history. Three children's books about Vasa have been written in Swedish and later translated into English, German, Danish, and Norwegian: The Vasa Saga by Bertil Almqvist

), and The Vasa Piglet by Björn Bergenholtz.

Vasa's unique status has drawn considerable attention and captured the imagination of more than two generations of scholars, tourists, model builders, and authors. Though historically unfounded, the popular perception of the building of the ship as a botched and disorganized affair (dubbed "the Vasa-syndrome") has been used by many authors of management literature as an educational example of how not to organize a successful business.
The museum has produced two versions of a documentary about the history and recovery of the ship; it is shown in the museum and has been released on VHS and DVD with narration in 16 languages. An educational computer game, now in its second generation, has been made and is used in the museum and on its website to explain the fundamentals of 17th century ship construction and stability. Several mass-produced model kits and countless custom-built models of the ship have been made. In 1991, a 308-tonne pastiche
