Kogge Ship - Koggesen (English spelling)

Japanese: コッゲ船 - コッゲせん（英語表記）Kogge

One of the various ships used in maritime commerce in medieval Europe, it was widely used in the Hanseatic trade in the north and became its main type of ship. It is also called a cog. It appeared in the 12th century and continued to be used until the 15th century, but the 13th and 14th centuries, the period when the Hanseatic League flourished, were also the period when the cog ships were at their peak. In terms of appearance, they are basically characterized by a single mast, a high deck, and a wide beam. Although it is a wooden sailing ship, it reflects the advances in medieval shipbuilding technology that accompanied the revival of commerce, and is more seaworthy and has a larger loading capacity than ships from the early Middle Ages.

中世ヨーロッパの海上通商で使用された各種船舶の一つで，北方のハンザ貿易でひろく用いられ，その主力船種となった。コグ船cogともよばれる。12世紀にすでに発生し，15世紀まで使用され続けるが，13～14世紀，つまりハンザ同盟の隆昌･全盛期が同時にコッゲ船の最盛期であった。外観上は，基本的には，1本マスト，高い甲板，船幅の広いことを特徴とする。木造帆船ではあるが，商業復活に伴う中世造船技術の進歩を反映し，中世初期の船舶に比し航洋性高く積載能力も大きい。
