FV Margiris, is the world's second largest fishing boat. It is a 9,500 GT super trawler and factory ship.

In 2012, Seafish Tasmania brought the ship (then named the Abel Tasman) to Australia. She was originally authorized to catch a quota of 18,000 tonnes of jack mackerel and redbait along the southern shores of the country. After protests against her use by environmental and fishing industry groups, the Australian government passed legislation prohibiting the trawler from fishing in Australian waters for two years. For this reason, Seafish Tasmania subsequently sold its stake in the vessel to Dutch company Parlevliet & Van der Plas. On March 6, 2013, after six months moored in Australian waters, she left Port Lincoln, having reassumed her original name of Margiris.

After leaving Australian waters, the vessel passed through Cook Strait, New Zealand on March 20, 2013. She was now flagged to Lithuania and owned by Atlantic High Sea Fishing Company.

Margiris arrived in Port of Penco, Chile on April 7, 2013. The vessel did not berth and steamed out of the bay to fish.

Margiris or Margis (died 1336) was a Duke of Samogitia, a medieval Lithuanian/Samogitian prince, mentioned in the chronicle of Wigand of Marburg as the heroic defender of Pilėnai in 1336. Not able to defend the castle against the siege of the Teutonic Knights, Margiris and other defenders decided to commit suicide, burning the castle and leaving no loot for the enemy.

Margiris held a high position in the Lithuanian society as evidenced by his duel with John of Luxemburg, King of Bohemia, who joined the Teutonic crusade against Lithuania and captured Medvėgalis in early 1329. After the rules of the duel were broken, Margiris had to pay a ransom. He did so with coins minted by Louis IV, Holy Roman Emperor stolen during the 1326 raid into Brandenburg. If Margiris was not from the ruling class, the King of Bohemia would consider it degrading to fight with him, and Margiris would not have a share of the spoils of war.

Regarding his family, chronicles mention only Margiris' son, who went to France after 1329 and whose wife was countess of Clermont of unknown name. Since the sources attest the high status and wealth of Margiris, historian Alvydas Nikžentaitis concluded that Margiris must have been a son of Butvydas and brother of Gediminas, Grand Duke of Lithuania.
