16th International Symposium on Boat & Ship Archaeology

111 Zadar, Croatia | 26 September – 1 October 2021 Janusz Różycki National Maritime Museum in Gdańsk, Poland The P1 wreck – 40 years after the discovery In 1979 during the survey of the remains of the submerged medieval harbour in Puck Lagoon a wreck of a lapstrake vessel was found. In 1983 the excavation has begun and documentation of approximately one third of the wreck was prepared. The timbers were radiocarbon dated on 1240s. The political situation in Poland in the late 1980s and 1990s did not allow to continue the research. In 1999 remains of the wreck had been covered with bags filled with sand. In 2019 the team of archaeologists from the NMM in Gdańsk had returned to the site for surveying the state of preservation of the construction and for securing the site in situ . During the works a photogrammetric documentation was prepared, while the remains of the wreck were covered with geotextile. The survey allowed to evaluate the state of preservation as wells as post-deposit processes that took place in 40 years since the discovery. The performed pho- togrammetry combined with the 1980s documentation allows the attempt to re- construct the vessel.
