The Original Cog
On October 8, 1962 construction workers met with port expansion works in the Weser before the Bremen District Rablinghausen on a hidden in the mud wreck. It turned out that it is the remains of a cog that one dated to the period around 1380. This dating is based on a dendrochronological analysis of annual rings of oak timbers from which the cog was built. It was up to that time the only preserved to this extent wreck of this ship type, which scientists previously knew only from the Hanseatic League and records of pictures, for example, on seals. It was suspected due to the incomplete appearance of the ship, that it had been carried away by a flood of his construction site.
The search for other wreckage lasted until July 1965 and sponsored a total of over 2,000 items of ship days. These were incorporated in the German Maritime Museum in small water tanks, to prevent further decay. We surveyed and cataloged them. They were then assembled as much as possible since 1972. It was possible to reconstruct the starboard side almost complete and the port side about one-third. The complete work is preserved in a 800,000 liter tank containing a mixture of water and polyethylene glycol. The water-soluble polymer should replace the water in the pores of the cog and so ensure that they do not continue shrinking. After 18 years the preservation process was completed in May 2000. Since the wreck is on display in a hall called the cog room of the German Maritime Museum.
Replicas
Ubena of Bremen
In 1986, first time the idea to construct a replica of the Bremen Cog. After several discussions and meetings of the association Hanse- Kogge shipyard was founded in the same year V. The following year began on a gridiron at the New Harbour Bremerhaven in the initial construction. Arrangements were under the supervision of classification society Germanischer Lloyd according to the plans of the German Maritime Museum, intending to make a replica in 1:1 scale. On 21 July 1988, the keel was laid, which was celebrated with great sympathy of the population took place. On August 18, 1990 we celebrated the launch of the baptized in the name of Ubena Bremen ship. On 27 July 1991, the cog launched on its maiden voyage, which took them from Lübeck to Danzig. Since she was probably the first cog in 600 years that sailed this route, she was accompanied on the entire route of radio and television reporters, which led to international interest in the population. Today the Ubena of Bremen has its moorings in Bremerhaven fishing port next to the fishing engine and museum ship Gera of the Historical Museum Bremerhaven.
The Ubena of Bremen has an overall length of 23.23 meters and a width of 7.62 meters. The deck is usually 3.14 meters above the waterline. The root sail has an area of 200 square meters, but by two Bonnets ( strips of fabric to increase the sail area ) can be expanded by 50 square meters size. The 23.80 meter mast has a maximum diameter of 0.65 meters. The volume of the cargo space of the cog is 160 cubic meters. She has charge with a draft of 2.25 meters. Without charge, this reduces by one meter. At the same 3,000 liters of fresh water, 3,000 liters of diesel and 2,500 liters of waste water can be carried in several tanks. The diesel oil drives the machine - and a generator set with 20 kW - a Deutz MWM 234 with 272 kW ( 370 hp). As the anchor Ubena of Bremen leads with a simple 300 kg heavy stick anchor. On the ship there are 16 berths, but for a trip requires a minimum crew of only four. The cog replica travels 4000-4500 miles, of which he usually travels around 1,200 under sail annually.
