Two boats, of which is believed to be a sister ship to the Swedish warship Vasa, was located at the archipelago close Stockholm this past week.
The boat from the 17th century has been found at a strait near Vaxholm on Tuesday (November 5).
Marine archaeologist Jim Hansson who discovered the warfare boat, said divers discovered the wreck in a place where many vessels are proven to be in the bottom of the sea.
Hansson said samples were taken in the boat he hoped would provide more hints about which boat it can be.
It’s currently in a museum after being salvaged in 1961 after 333 years in the base of the sea. Vasa is regarded as the world’s best-preserved 17th-century boat.
