The Vasa Capsized on its Maiden Voyage but was later recovered and is now on display at the Vasa Museum in Stockholm . Construction Henrik Hybertsson never got a chance to see the Vasa completed; he fell ill in late 1625 and died in the spring of 1627. The supervision for the shipbuilding was given to Henrik's assistant, Hein Jaconsson, another Dutch immigrant. In practice, while Henrik was ill, the responsibility was shared between him and his assistant Hein, leading to confusion and a lack of leadership. While the ship was being equipped Admiral Fleming ordered the Stability of the Vasa be tested. The standard Stability Test of the day was thirty sailors running from side to side trying to rock the boat. When this was attempted on ''Vasa'', the ship started tilting significantly after only three runs and the admiral ordered the test aborted, allegedly stating ''"had they run any more times, she would have went over"''. Surprisingly enough, neither Hein Jacobsson nor Johan Isbrandsson, the two ship builders in charge at the time, were present for the stability test. Boatswain Matsson, is said to have uttered ''"God hope it will stay on its keel"'' in response to the test. Shortly after the disaster, Ardent Hybertsson left Sweden and returned to Holland. Maiden voyage On August 10 , 1628, Captain Söfring Hansson ordered the ''Vasa'' to set Sail on her maiden voyage to the Harbor of Stockholm . The day was calm, and the only wind was a light breeze from the southwest. Her sails were not set until the southern outskirts of the harbor, but the Vasa sailed for less than a Nautical Mile before Capsizing after they were rigged. In the harbor a gust of Wind forced the ship on her port side, after which water started flowing in through her open Gun Port s. Vasa sank to a depth of 100 feet, around 100 yards from the shore. Despite the short distance to the land, between 30 and 50 people were trapped in the ship and perished. The exact number of casualities is unknown, as the only reports from the accident are lacking in substance and incomplete. Inquest At the following interrogation, Captain Söfring Hansson simply stated "a gust came". It is known from other reports that there was almost no wind at the time, so it did not take much to sink the ship. It has been calculated that if the Vasa's Center Of Gravity had been a mere 5-10 cm (2-4 inches) lower, she would not have capsized in the harbor. Borgenstam, Curt and Sandström, Anders. Page 49. . In the end, no guilty party could be found. The person responsible for the design, Henrik Hybertsson, was long dead and buried. The ship was built according the the specifications laid out by the King, and one couldn't very well punish the King. In the end, no one was punished or found guilty for negligence. The sinking of the Vasa was also a major economic disaster; the cost of the ship was more than 200 000 Riksdaler , which was about 5% of Sweden's GNP at the time. Why did the Vasa sink? During this period, the design requirements and calculations for building a ship only existed in the head of the shipwright. Scientific theories on vessel design or stability had not yet been developed, so important factors like the ship's center of gravity had to be estimated from the builder's experience.
Recovery After its sinking, most of the ship's valuable bronze cannons were soon recovered with the use of a Diving Bell . Access to the cannons required removing the decking at several levels. In 1956 , Anders Franzén thought of the possibility of recovering wrecks from the Baltic waters, because he figured that these waters were free from the Shipworm ''Teredo navalis''. He started looking for the ''Vasa'', and found her in an upright position at a depth of 32 meters. The wreck was lifted in a relatively straightforward way, by digging six tunnels under the hull, through which steel cables were to be attached to a pair of lifting Pontoons . The ship was lifted and brought to shallower water, where she was to be made watertight for the final lift. Her gun ports were closed by means of temporary lids, and all the holes from the iron bolts, which had all rusted away, were plugged. The final lift took place on April 24 , 1961 , after which she was put in a Dry Dock . Conservation Conservation of the ship itself was done using Polyethylene Glycol , a method that was also used years later in the conservation process of the Mary Rose . ''Vasa'' was sprayed with this glycol during 17 years, followed by slowly drying. Recent developments have shown that this conservation method, in time, makes the wood brittle and fragile. Over 26,000 artifacts have been found, including six original sails, still folded up. After the lifting of the wreck, the wreck site was searched for artifacts and over 700 Sculpture s were found. These sculptures were once attached to the ship, but the bolts had rusted away, causing the sculptures to fall to the bottom. Museum The ship can be seen in the Vasa Museum in Stockholm , Sweden .
