The hull was not only strong and therefore well suited to navigation in the North Sea and the Baltic, but it also enabled it to be relatively fast and sailor ...
Cog (in French), Kogghe (in Batave), Koggen (in German) or Coque, from the Spanish Coca or Cocha, or Concha in Latin, Coccha in Venetian, was typical of polyvalent cargo ships in northern Europe between the late Middle Ages and the era of great discoveries, although it later coincided with the nave, more typical of the Latin cargo ships. The cogue clinquart was the first and most emblematic of these northern ships. It was not created as an imitation of the nave but was a derivative of the Scandinavian cargo ships, bordered by clinkers, whereas in the Mediterranean it is the construction by freeboard, which, as in the past, predominated. The cogue was above all a functional, very large and ventruous cargo vessel: ratio of 3 to 1, rarely more than 30 meters long and 150 tons.
He possessed only one mast, but in the fifteenth century two or three, before turning into a caraque. The classical cogues used primarily in the Baltic by the rich merchant cities of the Hanse, united in 1241, were built in oak with ash couples, and with a bridge clearing a large hold well generally arranged for their slowness to be compensated by better management of transhipments, well-closed bilge panels to avoid waterways, and a single sail. The small end of the front, grafted on the extension of the bow, served only to moor the bulls. The hull was often reinforced by transverse barrots, like those that appear here. Quickly adopted by the English who also produced a local version of the Latin nave, the Roundhip, the Cogue had a raised foreleg for the archers and a small forequad almost always rectangular.
The stern was almost straight, supporting a wide rudder, the bar of which was still straight, the transverse lever system not appearing much later. The hull was adopted quickly in the Mediterranean, with local constructions, such as the freeboard, and a bow rounded instead of right. In fact, they became almost identical to the naves. This ship dominated the commercial roads as a three-century all-purpose building, evolving by first adopting a mizzen carrying a Latin sail on the quarter deck, and then a short bowsprit with a small square sail. He derived the Hulk, then the caraque in the north.
