stepping stones of maritime history

History

Polstjernan was a four-masted gaff-schooner from Mariehamn (Åland Islands, Finland), built 1919 in Dragsfjärd. The vessel was fitted with an auxillary machine and when she was launched, Polstjernan was considered the largest wooden vessel built in Finland.

In late 1926 the vessel carried a cargo of timber from Finland to England. While transitting Kiel Canal, the machine exploded on 20th October, setting the vessel ablaze. The wreck was still floating and obstructed navigation in the canal, so a salvage company was commissioned with towing the wreck away to its new location in Blankenese, where it served as breakwater ever since.

Description

In order to serve its new purpose as breakwater, the wreck was ballasted with boulders. In 1947, debris from a scrapped submarine was also dumped into the wreck as additional ballast.
