Swedish warship Vasa

It sank in 1628 and was recovered from the sea floor after 333 years.

 

It was 4 p.m. on August 10th of 1628, and the Vasa ship had barely left the docks of Stockholm harbor on its maiden voyage. Only 1300m into its voyage, a light gust of wind toppled the ship over on its side. As water flooded through the gun portals of the ship, it sank in the shallow waters of Stockholm harbor and lay there at 32m, forgotten. In 1956, it was found by Anders Franzen, a Swedish marine technician, and amateur naval archaeologist. It was salvaged between 1959-61 and can be found today in the museum that was specially built for it.

The use of different measuring systems on either side of the vessel caused its mass to be distributed asymmetrically, heavier to port. During construction both Swedish feet and Amsterdam feet were in use by different teams. Archaeologists have found four rulers used by the workmen who built the ship. Two were calibrated in Swedish feet, which had 12 inches, while the other two measured Amsterdam feet, which had 11 inches
