This video, recorded in Kampen town in the Netherlands, is about a reconstructed medieval cog ship.
About cog ships, from Wikipedia:
A cog (or cog-built vessels) is a type of ship that first appeared in the 10th century, and was widely used from around the 12th century on. Cogs were generally built of oak, which was an abundant timber in the Baltic region of Prussia. This vessel was fitted with a single mast and a square-rigged single sail. These vessels were mostly associated with seagoing trade in medieval Europe, especially the Hanseatic League, particularly in the Baltic Sea region.
In the eastern Netherlands, Kampen town was a Hanseatic League member.
Recently, Dutch archeologists announced the discovery of the wreck of a medieval cog in the IJssel river near Kampen.
Dutch NOS TV writes about it today:
At the end of the month it will be decided whether the wreck will be raised and whether it should go to a museum.
In the Netherlands, during the draining of the Flevo polders, already several wrecks of cogs have been found. One was restored with medieval wood. It sails since 1998 under the name Hanseatic Kampen Cog.
That is the ship in the video.
