The Oseberg ship is a well-preserved Viking ship discovered in a large burial mound at the Oseberg farm near Tønsberg in Vestfold county, Norway. The burial mound contained numerous grave goods and two female human skeletons. The ships internment into its burial mound dates from 834, but parts of the ship date from around 800, and the ship itself is thought to be older. It was excavated by Norwegian archaeologist Haakon Shetelig and Swedish archaeologist Gabriel Gustafson in 1904-1905. This ship is widely celebrated and has been called one of the finest finds to have survived the Viking Age. The ship and some of its contents are displayed at the Viking Ship Museum, Bygdøy, Oslo.The Gogstad ship is a Viking ship found beneath a burial mound at Gogstad farm in Sandar, Sandefjord, Vestfold, Norway. Excavation of Gogstadhaugen or Kongshaugen (from the Old Norse words kong meaning king and haugr meaning mound) revealed a ship burial dated back to 9th century. The site was excavated in 1880 by Nicolay Nicolaysen.The Gogstad ship is clinker-built, constructed largely of oak. The ship is 24 m long and 5 m wide. It is the largest in the Viking Ship Museum in Oslo. The ship was built to carry 32 oarsmen, and the oar holes could be hatched down when the ship was under sail. It utilized a square sail of c. 110 square meters, which, it is estimated, could propel the ship to over 12 knots. While the ship was traveling in shallow water, the rudder could be raised. Dendrochronological dating suggests that the ship was built of timber that was felled around 890 AD.The ship's design has been demonstrated to be very seaworthy. The Viking, an exact replica of the Gogstad ship crossed the Atlantic Ocean from Bergen, Norway to be exhibited at the World's Columbian Exposition in Chicago during 1893. Other known replicas include the Gaia, which currently has Sandefjord as its home port, and the Munin, (a half scale replica) located in Vancouver, BC.
