Viking Boats: The Wooden Crafting of Maritime Exploration
Introduction to Viking Shipbuilding
When exploring the maritime prowess of the Vikings, one must delve into the materials and methods they used to construct their boats. Central to this were the different types of wood that were chosen, namely oak and pine, with occasional use of birch and ash. This article explores the specific woods utilized by the Vikings for their ship-building, offering insights into their construction techniques and the challenges they faced.
Primary Woods: Oak and Pine
Vikings primarily used two main types of wood for their boats: oak and pine. Both woods had distinct characteristics that made them suitable for different parts of the ship. Oak was renowned for its strength and durability, making it the preferred choice for hulls and frames of longships. The sturdy nature of oak ensured that the boats could withstand the harsh conditions of the open seas. In contrast, pine was lighter and more buoyant, useful for planking and other structural components that needed to be both light and resilient.
Other woods like birch and ash were occasionally employed for specific parts, such as oars and smaller vessels. The choice of wood was critical for the performance and longevity of the ships, which were vital for the Vikings' explorations, trading expeditions, and raids across Europe and beyond.
Archaeological Evidence and Wooden Sources
Nordic boats, particularly those made from oak, have left a rich archaeological record. Depictions of boats from the Bronze Age can be found on the west coast of Sweden, indicating a long tradition of wooden shipbuilding in the region. Oaks were abundant in areas such as Denmark, specifically around Kattegatt, Kaupang, and Bergen, extending up to Uppsala. Viking ships departing from the west coast often used local oak, while the Varangian ships from the east utilized different species. Iceland, partly settled by ships from Scotland or Ireland, also utilized oak for its construction.
Construction Techniques and Wood Usage
According to archaeological finds and written accounts, the majority of vessels made by Viking Age Scandinavians were constructed from white oak, with the exception of their masts and yards, which were typically made from white or yellow pine. A few vessels have been found with either a few pine boards used in repairs or were entirely made of pine, though these were less desirable as they rot at a much faster rate than oak.
The planks, keel, and ribs were shaped using axes. The process began with the felling of an oak tree, which was then split into halves and further split to make strakes or planks. The ribs, however, were attached to the keel and then held together by iron nails. The ribs were carefully fitted to each other, with the seams between the planks sealed using wool and tar to ensure watertightness. For the hull, green oak was often used, as it was easier to cut and shape. After construction, the ship was left to dry out over a year, allowing the wood to settle and become more stable.
Upper strakes of the hull, requiring less strength, could be made from pine or spruce. Examples of ships with these woods may represent replacement strakes, as the upper parts of the ship saw more wear and tear and were easier to replace. The Vikings' expertise in shipbuilding, combining different woods and innovative techniques, ensured the success of their maritime endeavors.
