At the time of the First World Maritime Revolution around 1300, the Venetian General Commandment of the Sea reorganized its navy in 1330; its war ships operated from Corfu to Levant and on the Levant, while the Venetian Adriatic Fleet stationed for centuries on the island of Hvar. The city of Hvar was developing under the Venetian rule (1420–1797) as a naval arsenal for building (in times of conjucture), repair and maintenance of the patrol galleys of the eastern Adriatic towns-communes under Venice. It was a fast and efficient replacement of ships on the slipways, as well as quality building and maintenance of serial ships on the ground floor of a monumental arsenal building. The naval arsenal in Hvar, due to its favorable geographical location was the extended arm of the Great arsenal of Venice, and thanks to this fact, the Hvar arsenal transmitted new and developed its own know-how and experience, and technologically, socially and economically influenced the development of the city of Hvar, middle Dalmatia and especially of Adriatic shipbuilding, although in the circumstances of a rigid governance of the Venetian oligarchy, to the interests and profits of which all was subordinated and strictly supervised.
