Аннотация: In 2018, on the Vologda shore of Lake Onega (Russia, Vologda Oblast), the skeleton of an ancient wooden ship was thrown out by storm. The ship’s construction and preliminary dendrochronological analysis of wood samples indicate that this ship was made in the middle of the 17th century and most of the wooden elements are interconnected (“sewn”) with a special “vice” (roots and branches of conifers). Research continues, in 2019 and early 2020 additional wood samples were collected for advanced dendrochronological analysis, this material is studied and it is unique not only at the local, regional, but even at the national and global levels, because it allows you to look into the depths of history and clearly demonstrates the techniques and technologies used by medieval Russian shipbuilders, and also makes it possible to compare with ship manufacturing technologies in other countries of that time. The author also considers water and water-ways and trade and trade (types of goods transported by ships) in Russia of the 17th century in the north of Eurasia (the European North), these are the possible directions of movement of the vessel under study. It is assumed, after conducting comprehensive studies of the skeleton of the wooden vessel under consideration, to perform a comparative analysis of its structure with preserved wooden vessels of the same time found in other countries, in particular on the Scandinavian Peninsula.
