Puck 3 was lying at an acute angle to the vertical, with one end without stern-post
barely 50 cm below the sea surface and the other buried under a thick layer
of mud and peat. In 1983 was initially uncovered at one end for a length of
approximately 2m. After having been catalogued under water, in 1990 P-3 was
dismantled and taken to the Polish Maritime Museums Conservation Laboratory
where it underwent further examination, cataloguing and conservation. In the
course of the preparations for recovering P-3, another wreck denoted as P-5,
was happened upon. This is remains of a large vessel, over 12 meter in length,
dated to 13th century.
A T-shaped keel of P-3 was flatly cut at one end for the vertical joint with the stem oft the sternpost. At this end three shallow, square mortises were cut into its upper surface. The other end of the keel carved out of a naturally curved timber, the post triangular in cross section, appeared to be the stem. A step was curved into its inner side for the garboard strake. Forward of the step vertical shallow cuts were made on both sides of the stem. A shallow groove, resembling a rabbet, a rectangular hole was cut through the stem. The hood ends of the four lowermost strakes were connected to the stem through wings nailed to either side of it. P-3 stem was a naturally bent beam, to the sides of which were nailed suitably shaped pieces of wood containing the rabbets for the lower strakes of the planking.
The strakes, made of overlapping planks with length varying between 1m and 3 m, were joined in the lapstrake manner and fastened to each other with treenails. Moss was used for luting. A forward most frame was found in situ fastened to the strakes bit not to the keel. The floor timbers, carved out of naturally curved wood, were inserted in the hull at 0,95 - 1,35 m intervals. Beams were set on top of floor timbers. The upper hull was further reinforced by vertical knees fastened on top of the beams. The longest beam had a semicircular notch carved into the side. On one of these thwarts, the longest of those recovered, there is a semicircular cut-out. This must have been part of the mast yoke, so the boat itself must have been a sailing vessel. Unfortunately, there is no sign of the mast step in the wreck.
Dendrochronological analyses showed that the wood used to build P- 3 was felled after 1155 AD. The conservation work on the wreck is continuing in the PMM's conservation laboratory, where it is treated with PEG.
