In 1962, a wreck was found during reclamation work near Lake Lebsko in meadows adjoining the village Czarnowsko. The Polish Maritime Museum carried out the excavations in the summer of 1983 (August 2-12) after some preliminary preparations. The wreck was laying some 300 m from the present-day shore line and about 30 cm below the surface of the meadow. After uncovering it and making a complete record of it, the wreck was dismantled and transported to the Museums Conservation Laboratory where it was given the appropriate conservation treatment.
This was bottom part of a boat which at that time comprised the intact keel, the lower part of the stem-post, fragments of six strakes of the starboard side and five strakes of the port side. During the reclamation work mentioned above, the mechanical excavator digging the drainage ditch into the wreck, breaking it into two parts and destroying a c. 2 metre long section of the hull.
In construction, the Czarnowsko II boat is redolent of the Pomeranian wrecks found in earlier years. Thus it was built of oak on a T-shaped which measured approximately 11-12 m in length. The surviving part of the stem-post was stepped, as were the early medieval boats from Gdansk region. It was joined to the keel through a vertical flat scarf joggled in the middle. The stem had on its inner side at the lower end a step for the fastening of the garboard strakes. The garboards were fastened in this place with iron nails. The hooding ends of the upper strakes were also fastened with iron nails to the stem.
Nine recovered frames had been inserted in the hull at 83 - 96 m intervals. The above-water part of the hull was probably reinforced by thwarts or cross-beams resting on the ends of the floor-timbers which were extended up the sides by knees. One such knee was found on site. The strakes, 24-29 cm wide and 2,2-2,5 cm thick, were joined together in the lapstrake manner and fastened with wedged treenails driven at intervals of 6-6,5 m. The luting in the seams was of moss. A total of five planking strakes to port and six to starboard were preserved. The floor timbers, joggled to fit the planking, were fastened to the hull with treenails. The wreck was dated by C14 analysis to the 9th-11th century.
