The small pram's flat bottom is almost entirely preserved, while the lapstrake side planking has partially collapsed. Half-frames were inserted in an alternating manner. This is a typical pram, which was used for a fishing operation on the lake in the early 20th century.

The wreck of this fishing pram was discovered by recreational divers of the TSG Ahrensburg and investigated in 2012 by the Scientific Diving Association (SDA Kiel) under the lead of Hubert Pinto de Kraus and wreck-diving enthusiasts.

Although the visibility in the lake is almost nil, an artist's impression of the wreck was produced (see above) and a Structure-from-Motion (SfM) model was generated on the basis of 500 photos (see below).

In accord with the responsible authority - the State Archaeology Department of Schleswig-Holstein (ALSH) - the site is monitored by the hobby archaeologist and local resident Elmar Klemm, who reports frequently from the wreck in his "home waters".
