Harbour informations about: Wharf

There is plenty of comparative data and documentation concerning the size of ships and their length/breadth ration, to assume that the slipways at Dor were not shipsheds but rather a shipwharf. Considering the width/length of the slipways at Dor, one may reconstruct the size of the vessels that could be hauled up on them:

  • the eastern slip (nr.1) – vessels of 4x24 m
  • the middle slip (nr. 2) – vessels of 4.5x26 m
  • the western slip (nr. 3) – vessels of 5x20 m.

The ration of 1:4 is characteristic for merchant ships while the others of 1:6 and 1:5.7 would be appropriate to oared naval vessels.

Parallels

There are no good parallels for Dor’s slipways to be found in other sites in the Levant coast. Such installations come only from the Greek world. Similar structures were found in the Port of Pireus, Greece and in North Africa. The installations at Pireus were part of the dockyard/arsenal belonging the Athenian maritime power. The length of these slips was 38-40 m, the width almost 6 m and the angle of inclination is about 6º. At the base of the slips was a raised area, and along its center a shallow channel was cut to fit the keel of the vessels. Almost identical to the Pireus complex is found in the sunken remains of the Hellenistic harbor of Apollonia, in North Africa (Libya). Due to their being underwater at present, it is difficult to establish the exact length of the slips. An estimated range for their length is between 28 to 40 m. The width is about 6 m and the angle of inclination is 4º. The base of the slips is identical to those found at Pireus complex.

The sites described above helped to conclude that the slipways at Dor were used for repairs and maintaining ships that anchored in the in the North Bay and in the Tantura Lagoon. The date of the Pireus and Apollonia (Libya) installations is not defined but cannot be earlier than 3rd - 2nd century BCE. During this period the standard vessels were the trireme which measured 38 m in length and 5.5 - 6 m in width. The dimensions of the docks at Dor indicate that they were not adequately fitted for triremes. It should be noted that the moderate inclination of 5º and the flat bottom of the slips are more suited for merchantmen rather than military vessels. The Dor docks could be dated to the 6th-5th century BCE, deduced from the Athenian sherds found on the eastern side of the installation complex.




Dor


In the region of former Wolin were localized four ports and harbours– main port was found in region centre of present city (fig.4). Build wharf of main port begun in 880 year lasted to 896-900 year. One localize street passing in port footbridge, which was twice rebuilt in distances 50 of years among 900 and 995 with year. In archaeological material from port we can observe gradual pushing oneself of construction in direction deeper waters, every level of construction was added in result of settlement of construction on wet ground. In 1952 in caisson No 1 being found on bank present troughs of river, one met on pale constructions dated on X XII in. In 1985 in excavation trench No 3. 60 of metres from present bank, on depths 6 m one found wooden constructions being with remainders of wharf port - in form oak - logs (halved of trunks) creating constructions of wall of wharf. From land wall strengthened and stiffened were beams fulfilling function pull-offs, which fixed former in ground at help oak pegs (fig.5). During researches in region of former port, in excavation trench No 8, on 2, 6 metre was found fragment of keel of boat, which used secondarily as fulfilment of side of wharf (fig.6). On base of dendrochronological analysis one fixed, that keel originates from boat built in years 860 870. Disassembly of boat and secondary used of keel happened about 966 year.
