16th International Symposium on Boat & Ship Archaeology

104 16 th International Symposium on Boat & Ship Archaeology Paweł Litwinienko National Maritime Museum in Gdańsk, Poland The digital reconstruction of the P3 wreck hull The P3 wreck was discovered in the submerged remains of the medieval harbour in Puck Lagoon, Poland in 1979, one of the four lapstrake vessels found at the site. It was recorded underwater and salvaged in 1990; the individual planks and other timbers were then passed on to conservation in the National Maritime Museum in Gdańsk. The wreck is a clinker vessel, built accordingly to the Slavic shipbuild- ing tradition and interpreted as a cargo ship, dated dendrochronologically to the 1150s. Almost half of the hull is preserved, including the stem. Taking into con- sideration the scarcity of such well-preserved finds in the Southern Baltic, the P3 wreck remains an important source of our knowledge on the maritime tradition of the region in the times before Hanza. Following the procedures developed and used for the digital reconstruction of another Puck harbour wreck, the longship P2, the timbers of the P3 cargo ves- sel were documented in 3D using the Faro Arm recording device. With the use of field documentation this allowed digital reassembly of the individual timbers into the wreck as it was originally found. On that basis a reconstruction of the com- plete hull was prepared and tested for hydrostatic properties.
